This pull request updates GenerateUnsafeProjection to support StructType. If an input struct type is backed already by an UnsafeRow, GenerateUnsafeProjection copies the bytes directly into its buffer space without any conversion. However, if the input is not an UnsafeRow, GenerateUnsafeProjection runs the code generated recursively to convert the input into an UnsafeRow and then copies it into the buffer space.
Also create a TungstenProject operator that projects data directly into UnsafeRow. Note that I'm not sure if this is the way we want to structure Unsafe+codegen operators, but we can defer that decision to follow-up pull requests.

This PR is based on #6796 authored by rtreffer.
To support large decimal precisions (> 18), we do the following things in this PR:
1. Making `CatalystSchemaConverter` support large decimal precision
Decimal types with large precision are always converted to fixed-length byte array.
2. Making `CatalystRowConverter` support reading decimal values with large precision
When the precision is > 18, constructs `Decimal` values with an unscaled `BigInteger` rather than an unscaled `Long`.
3. Making `RowWriteSupport` support writing decimal values with large precision
In this PR we always write decimals as fixed-length byte array, because Parquet write path hasn't been refactored to conform Parquet format spec (see SPARK-6774 & SPARK-8848).
Two follow-up tasks should be done in future PRs:
- [ ] Writing decimals as `INT32`, `INT64` when possible while fixing SPARK-8848
- [ ] Adding compatibility tests as part of SPARK-5463

This PR removes the old Parquet support:
- Removes the old `ParquetRelation` together with related SQL configuration, plan nodes, strategies, utility classes, and test suites.
- Renames `ParquetRelation2` to `ParquetRelation`
- Renames `RowReadSupport` and `RowRecordMaterializer` to `CatalystReadSupport` and `CatalystRecordMaterializer` respectively, and moved them to separate files.
This follows naming convention used in other Parquet data models implemented in parquet-mr. It should be easier for developers who are familiar with Parquet to follow.
There's still some other code that can be cleaned up. Especially `RowWriteSupport`. But I'd like to leave this part to SPARK-8848.

Current scheduling algorithm allocates one core at a time and in doing so ends up ignoring spark.executor.cores.

Currently nondeterministic expression is broken without a explicit initialization phase.
Let me take `MonotonicallyIncreasingID` as an example. This expression need a mutable state to remember how many times it has been evaluated, so we use `transient var count: Long` there. By being transient, the `count` will be reset to 0 and **only** to 0 when serialize and deserialize it, as deserialize transient variable will result to default value. There is *no way* to use another initial value for `count`, until we add the explicit initialization phase.
Another use case is local execution for `LocalRelation`, there is no serialize and deserialize phase and thus we can't reset mutable states for it.
