If we set `hive.exec.stagingdir=.test-staging\tmp`,
But the staging directory is still `.hive-staging` on Windows OS.
Reasons for failure:
Test code:
```
val path = new Path("C:\\test\\hivetable")
println("path.toString: " + path.toString)
println("path.toUri.getPath: " + path.toUri.getPath)
```
Output:
```
path.toString: C:/test/hivetable
path.toUri.getPath: /C:/test/hivetable
```
We can see that `path.toUri.getPath` has one more separator than `path.toString`, and the separator is ' / ', not ' \ '
So `stagingPathName.stripPrefix(inputPathName).stripPrefix(File.separator).startsWith(".")` will return false

## What changes were proposed in this pull request?
Currently, in `ParquetFilters` and `OrcFilters`, if the child predicate of `Or` operator can't be entirely pushed down, the predicates will be thrown away.
In fact, the conjunctive predicates under `Or` operators can be partially pushed down.
For example, says `a` and `b` are convertible, while `c` can't be pushed down, the predicate
`a or (b and c)`
can be converted as
`(a or b) and (a or c)`
We can still push down `(a or b)`.
We can't push down disjunctive predicates only when one of its children is not partially convertible.
This PR also improve the filter pushing down logic in `DataSourceV2Strategy`. With partial filter push down in `Or` operator, the result of `pushedFilters()` might not exist in the mapping `translatedFilterToExpr`. To fix it, this PR changes the mapping `translatedFilterToExpr` as leaf filter expression to `sources.filter`, and later on rebuild the whole expression with the mapping.

## What changes were proposed in this pull request?
Currently we have an analyzer rule, which resolves the output columns of data source v2 writing plans, to make sure the schema of input query is compatible with the table.
However, not all data sources need this check. For example, the `NoopDataSource` doesn't care about the schema of input query at all.
This PR introduces a new table capability: ACCEPT_ANY_SCHEMA. If a table reports this capability, we skip resolving output columns for it during write.
Note that, we already skip resolving output columns for `NoopDataSource` because it implements `SupportsSaveMode`. However, `SupportsSaveMode` is a hack and will be removed soon.

When we upgraded the built-in Hive to 2.3.4, the current `hive-thriftserver` module is not compatible, such as these Hive changes:
1. [HIVE-12442](https://issues.apache.org/jira/browse/HIVE-12442) HiveServer2: Refactor/repackage HiveServer2's Thrift code so that it can be used in the tasks
2. [HIVE-12237](https://issues.apache.org/jira/browse/HIVE-12237) Use slf4j as logging facade
3. [HIVE-13169](https://issues.apache.org/jira/browse/HIVE-13169) HiveServer2: Support delegation token based connection when using http transport

The below example works with both Mysql and Hive, however not with spark.
```
mysql> select * from date_test where date_col >= '2000-1-1';
+------------+
| date_col |
+------------+
| 2000-01-01 |
+------------+
```
The reason is that Spark casts both sides to String type during date and string comparison for partial date support. Please find more details in https://issues.apache.org/jira/browse/SPARK-8420.
Based on some tests, the behavior of Date and String comparison in Hive and Mysql:
Hive: Cast to Date, partial date is not supported
Mysql: Cast to Date, certain "partial date" is supported by defining certain date string parse rules. Check out str_to_datetime in https://github.com/mysql/mysql-server/blob/5.5/sql-common/my_time.c
As below date patterns have been supported, the PR is to cast string to date when comparing string and date:
```
`yyyy`
`yyyy-[m]m`
`yyyy-[m]m-[d]d`
`yyyy-[m]m-[d]d `
`yyyy-[m]m-[d]d *`
`yyyy-[m]m-[d]dT*

When a null in a nested field in struct, casting from the struct throws error, currently.

at org.apache.spark.sql.catalyst.expressions.Cast.$anonfun$castStruct$1(Cast.scala:603)
```
Similarly, inline table, which casts null in nested field under the hood, also throws an error.
```scala
scala> sql("select * FROM VALUES (('a', (10, null))), (('b', (10, 50))), (('c', null)) AS tab(x, y)").show
org.apache.spark.sql.AnalysisException: failed to evaluate expression named_struct('col1', 10, 'col2', NULL): NullType (of class org.apache.spark.sql.t

…rtBasedAggregate
Normally, the aggregate operations that are invoked for an aggregation buffer for User Defined Aggregate Functions(UDAF) follow the order like initialize(), update(), eval() OR initialize(), merge(), eval(). However, after a certain threshold configurable by spark.sql.objectHashAggregate.sortBased.fallbackThreshold is reached, ObjectHashAggregate falls back to SortBasedAggregator which invokes the merge or update operation without calling initialize() on the aggregate buffer.

### Background:
The data source option `pathGlobFilter` is introduced for Binary file format: https://github.com/apache/spark/pull/24354 , which can be used for filtering file names, e.g. reading `.png` files only while there is `.json` files in the same directory.
### Proposal:
Make the option `pathGlobFilter` as a general option for all file sources. The path filtering should happen in the path globbing on Driver.
### Motivation:
Filtering the file path names in file scan tasks on executors is kind of ugly.
### Impact:
1. The splitting of file partitions will be more balanced.
2. The metrics of file scan will be more accurate.
3. Users can use the option for reading other file sources.

derives that based on shaded package name.
- updated the `org/spark_project` shade package prefix to `org/sparkproject`

`BaseStreamingSource` and `BaseStreamingSink` is used to unify v1 and v2 streaming data source API in some code paths.
This PR removes these 2 interfaces, and let the v1 API extend v2 API to keep API compatibility.
The motivation is https://github.com/apache/spark/pull/24416 . We want to move data source v2 to catalyst module, but `BaseStreamingSource` and `BaseStreamingSink` are in sql/core.

Because a review is resolved during analysis when we create a dataset, the content of the view is determined when the dataset is created, not when it is evaluated. Now the explain result of a dataset is not correctly consistent with the collected result of it, because we use pre-analyzed logical plan of the dataset in explain command. The explain command will analyzed the logical plan passed in. So if a view is changed after the dataset was created, the plans shown by explain command aren't the same with the plan of the dataset.
```scala
scala> spark.range(10).createOrReplaceTempView("test")
scala> spark.range(5).createOrReplaceTempView("test2")
scala> spark.sql("select * from test").createOrReplaceTempView("tmp001")
scala> val df = spark.sql("select * from tmp001")
scala> spark.sql("select * from test2").createOrReplaceTempView("tmp001")
scala> df.show

Before:
```scala
== Parsed Logical Plan ==
'Project [*]
+- 'UnresolvedRelation `tmp001`
== Analyzed Logical Plan ==
id: bigint
Project [id#2L]
+- SubqueryAlias `tmp001`
+- Project [id#2L]
+- SubqueryAlias `test2`
+- Range (0, 5, step=1, splits=Some(12))
== Optimized Logical Plan ==
Range (0, 5, step=1, splits=Some(12))
== Physical Plan ==
*(1) Range (0, 5, step=1, splits=12)
```
After:
```scala
== Parsed Logical Plan ==
'Project [*]
+- 'UnresolvedRelation `tmp001`
== Analyzed Logical Plan ==
id: bigint
Project [id#0L]
+- SubqueryAlias `tmp001`
+- Project [id#0L]
+- SubqueryAlias `test`
+- Range (0, 10, step=1, splits=Some(12))
== Optimized Logical Plan ==
Range (0, 10, step=1, splits=Some(12))
== Physical Plan ==
*(1) Range (0, 10, step=1, splits=12)
```
To fix it, this passes query execution of Dataset when explaining it. The query execution contains pre-analyzed plan which is consistent with Dataset's result.

**Description from JIRA**
For the JDBC option `query`, we use the identifier name to start with underscore: s"(${subquery}) _SPARK_GEN_JDBC_SUBQUERY_NAME${curId.getAndIncrement()}". This is not supported by Oracle.
The Oracle doesn't seem to support identifier name to start with non-alphabet character (unless it is quoted) and has length restrictions as well. [link](https://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements008.htm)
In this PR, the generated alias name 'SPARK_GEN_JDBC_SUBQUERY_NAME<int value>' is fixed to remove "_" prefix and also the alias name is shortened to not exceed the identifier length limit.
## How was this patch tested?
Tests are added for MySql, Postgress, Oracle and DB2 to ensure enough coverage.

## What changes were proposed in this pull request?
In SPARK-27612, one correctness issue was reported. When protocol 4 is used to pickle Python objects, we found that unpickled objects were wrong. A temporary fix was proposed by not using highest protocol.
It was found that Opcodes.MEMOIZE was appeared in the opcodes in protocol 4. It is suspect to this issue.
A deeper dive found that Opcodes.MEMOIZE stores objects into internal map of Unpickler object. We use single Unpickler object to unpickle serialized Python bytes. Stored objects intervenes next round of unpickling, if the map is not cleared.
We has two options:
1. Continues to reuse Unpickler, but calls its close after each unpickling.
2. Not to reuse Unpickler and create new Unpickler object in each unpickling.
This patch takes option 1.

## What changes were proposed in this pull request?
`Row.toString` is currently causing the useless creation of an `Array` containing all the values in the row before generating the string containing it. This operation adds a considerable overhead.
The PR proposes to avoid this operation in order to get a faster implementation.
## How was this patch tested?
Run
```scala
test("Row toString perf test") {
val n = 100000
val rows = (1 to n).map { i =>
Row(i, i.toDouble, i.toString, i.toShort, true, null)
}
// warmup
(1 to 10).foreach { _ => rows.foreach(_.toString) }
val times = (1 to 100).map { _ =>
val t0 = System.nanoTime()
rows.foreach(_.toString)
val t1 = System.nanoTime()
t1 - t0
}
// scalastyle:off println
println(s"Avg time on ${times.length} iterations for $n toString:" +
s" ${times.sum.toDouble / times.length / 1e6} ms")
// scalastyle:on println
}
```
Before the PR:
```
Avg time on 100 iterations for 100000 toString: 61.08408419 ms
```
After the PR:
```
Avg time on 100 iterations for 100000 toString: 38.16539432 ms
```
This means the new implementation is about 1.60X faster than the original one.

After we added other fields, `arguments`, `examples`, `note` and `since` at SPARK-21485 and `deprecated` at SPARK-27328, we have nicer way to separately describe extended usages.
`extended` field and method at `ExpressionDescription`/`ExpressionInfo` is now pretty useless - it's not used in Spark side and only exists to keep backward compatibility.
This PR proposes to deprecate it.
## How was this patch tested?
Manually checked the deprecation waring is properly shown.

This PR adds SparkR with Arrow optimization documentation.
Note that looks CRAN issue in Arrow side won't look likely fixed soon, IMHO, even after Spark 3.0.
If it happen to be fixed, I will fix this doc too later.
Another note is that Arrow R package itself requires R 3.5+. So, I intentionally didn't note this.
