Update jquery -> 1.12.4, datatables -> 1.10.18, mustache -> 2.3.12.
Add missing mustache license
## How was this patch tested?
I manually tested the UI locally with the javascript console open and didn't observe any problems or JS errors. The only 'risky' change seems to be mustache, but on reading its release notes, don't think the changes from 0.8.1 to 2.x would affect Spark's simple usage.

## What changes were proposed in this pull request?
In the current file source V2 framework, the schema of `FileScan` is not returned correctly if there are overlap columns between `dataSchema` and `partitionSchema`. The actual schema should be
`dataSchema - overlapSchema + partitionSchema`, which might have different column order from the pushed down `requiredSchema` in `SupportsPushDownRequiredColumns.pruneColumns`.
For example, if the data schema is `[a: String, b: String, c: String]` and the partition schema is `[b: Int, d: Int]`, the result schema is `[a: String, b: Int, c: String, d: Int]` in current `FileTable` and `HadoopFsRelation`. while the actual scan schema is `[a: String, c: String, b: Int, d: Int]` in `FileScan`.
To fix the corner case, this PR proposes that the output schema of `FileTable` should be `dataSchema - overlapSchema + partitionSchema`, so that the column order is consistent with `FileScan`.
Putting all the partition columns to the end of table schema is more reasonable.

With this change, unnecessary file scans are avoided in case of Limit 0 queries.
I added a case (rule) to `PropagateEmptyRelation` to replace `GlobalLimit 0` and `LocalLimit 0` nodes with an empty `LocalRelation`. This prunes the subtree under the Limit 0 node and further allows other rules of `PropagateEmptyRelation` to optimize the Logical Plan - while remaining semantically consistent with the Limit 0 query.
For instance:
**Query:**
`SELECT * FROM table1 INNER JOIN (SELECT * FROM table2 LIMIT 0) AS table2 ON table1.id = table2.id`
**Optimized Plan without fix:**
```
Join Inner, (id#79 = id#87)
:- Filter isnotnull(id#79)
: +- Relation[id#79,num1#80] parquet
+- Filter isnotnull(id#87)
+- GlobalLimit 0
+- LocalLimit 0
+- Relation[id#87,num2#88] parquet
```
**Optimized Plan with fix:**
`LocalRelation <empty>, [id#75, num1#76, id#77, num2#78]`
## How was this patch tested?
Added unit tests to verify Limit 0 optimization for:
- Simple query containing Limit 0
- Inner Join, Left Outer Join, Right Outer Join, Full Outer Join queries containing Limit 0 as one of their children
- Nested Inner Joins between 3 tables with one of them having a Limit 0 clause.
- Intersect query wherein one of the subqueries was a Limit 0 query.

In `UnsafeExternalSorter.SpillableIterator#loadNext()` takes lock on the `UnsafeExternalSorter` and calls `freePage` once the `lastPage` is consumed which needs to take a lock on `TaskMemoryManager`. At the same time, there can be another MemoryConsumer using `UnsafeExternalSorter` as part of sorting can try to `allocatePage` needs to get lock on `TaskMemoryManager` which can cause spill to happen which requires lock on `UnsafeExternalSorter` again causing deadlock. This is a classic deadlock situation happening similar to the SPARK-26265.
To fix this, we can move the `freePage` call in `loadNext` outside of `Synchronized` block similar to the fix in SPARK-26265

In the PR, we raise an AnalysisError when we detect the presense of aggregate expressions in where clause. Here is the problem description from the JIRA.
Aggregate functions should not be allowed in WHERE clause. But Spark SQL throws an exception when generating codes. It is supposed to throw an exception during parsing or analyzing.
Here is an example:
```
val df = spark.sql("select * from t where sum(ta) > 0")
df.explain(true)
df.show()
```
Resulting exception:
```
Exception in thread "main" java.lang.UnsupportedOperationException: Cannot generate code for expression: sum(cast(input[0, int, false] as bigint))
at org.apache.spark.sql.catalyst.expressions.Unevaluable.doGenCode(Expression.scala:291)

at scala.Option.getOrElse(Option.scala:138)
```
Checked the behaviour of other database and all of them return an exception:
**Postgress**
```

```

In the PR, I propose to deprecate the `from_utc_timestamp()` and `to_utc_timestamp`, and disable them by default. The functions can be enabled back via the SQL config `spark.sql.legacy.utcTimestampFunc.enabled`. By default, any calls of the functions throw an analysis exception.
One of the reason for deprecation is functions violate semantic of `TimestampType` which is number of microseconds since epoch in UTC time zone. Shifting microseconds since epoch by time zone offset doesn't make sense because the result doesn't represent microseconds since epoch in UTC time zone any more, and cannot be considered as `TimestampType`.

I haven't tested by myself on Windows and I am not 100% sure if this is going to cause an actual problem.
However, this one line:
827383a97c/sql/catalyst/src/main/java/org/apache/spark/sql/catalyst/expressions/ExpressionInfo.java (L82)
made me to investigate a lot today.
Given my speculation, if Spark is built in Linux and it's executed on Windows, it looks possible for multiline strings, like,
5264164a67/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/mathExpressions.scala (L146-L150)
to throw an exception because the newline in the binary is `\n` but `System.lineSeparator` returns `\r\n`.
I think this is not yet found because this particular codes are not released yet (see SPARK-26426).
Looks just better to loosen the condition and forget about this stuff.
This should be backported into branch-2.4 as well.

After [SPARK-26856](https://github.com/apache/spark/pull/23797), `Kinesis` Python UT fails with `Found multiple JARs` exception due to a wrong pattern.

please remove all but one
```
It's because the pattern was changed in a wrong way.
**Original**
```python

kinesis_asl_assembly_dir, "target/%s_*.jar" % name_prefix))

In addition, after SPARK-26856, the utility function `search_jar` is shared to find `avro` jar files which are identical for both `sbt` and `mvn`. To sum up, The current jar pattern parameter cannot handle both `kinesis` and `avro` jars. This PR splits the single pattern into two patterns.

When there is a `Union`, the reported output datatypes are the ones of the first plan and the nullability is updated according to all the plans. For complex types, though, the nullability of their elements is not updated using the types from the other plans. This means that the nullability of the inner elements is the one of the first plan. If this is not compatible with the one of other plans, errors can happen (as reported in the JIRA).
The PR proposes to update the nullability of the inner elements of complex datatypes according to most permissive value of all the plans.

## What changes were proposed in this pull request?
Add AL2 license to metadata of all .md files.
This seemed to be the tidiest way as it will get ignored by .md renderers and other tools. Attempts to write them as markdown comments revealed that there is no such standard thing.

In the first PR for file source V2, there was a rule for falling back Orc V2 table to OrcFileFormat: https://github.com/apache/spark/pull/23383/files#diff-57e8244b6964e4f84345357a188421d5R34
As we are migrating more file sources to data source V2, we should make the rule more generic. This PR proposes to:
1. Rename the rule `FallbackOrcDataSourceV2 ` to `FallBackFileSourceV2`.The name is more generic. And we use "fall back" as verb, while "fallback" is noun.
2. Rename the method `fallBackFileFormat` in `FileDataSourceV2` to `fallbackFileFormat`. Here we should use "fallback" as noun.
3. Add new method `fallbackFileFormat` in `FileTable`. This is for falling back to V1 in rule `FallbackOrcDataSourceV2 `.
