sql: Add support of escape quote in CSV (#9231) 
This commit modifies csv parser, a fork of golang csv
parser to support a custom quote escape character.

The quote escape character is used to escape the quote
character when a csv field contains a quote character
as part of data.

26e760ee62 Fix JSON Close data race. (#8486) 
The JSON stream library has no safe way of aborting while

Since we cannot expect the called to safely handle "Read" and "Close" calls we must handle this.

Also any Read error returned from upstream will crash the server. We preserve the errors and instead always return io.EOF upstream, but send the error on Close.

`readahead v1.3.1` handles Read after Close better.

Updates to `progressReader` is mostly to ensure safety.

Fixes #8481

be313f1758 S3 Select: Workaround java buffer size (#8312) 
Updates #7475

The Java implementation has a 128KB buffer and a message must be emitted before that is used. #7475 therefore limits the message size to 128KB. But up to 256 bytes are written to the buffer in each call. This means we must emit a message before shorter than 128KB.

Therefore we change the limit to 128KB minus 256 bytes.

bd56f80250 Fix ignored alias for aggregate result in S3 Select (#7849) 
The SQL parser as it stands right now ignores alias for aggregate
result, e.g. `SELECT COUNT(*) AS thing FROM s3object` doesn't actually
return record like `{"thing": 42}`, it returns a record like `{"_1": 42}`.
Column alias for aggregate result is supported in AWS's S3 Select, so
this commit fixes that by respecting the `expr.As` in the expression.

Also improve test for S3 select

On top of testing a simple `SELECT` query, we want to test a few more
"advanced" queries (e.g. aggregation).

Convert existing tests into table driven tests[1], and add the new test
cases with "advanced" queries into them.
