Fixes for Code Model for query expressions.

The serialization code for query expressions did not match the actual code model in a various places. Also, the model for into expressions was incorrect. Also changed the way that order by AST nodes are constructed because the tokens for ascending and descending always report 0 as their token id value.

More mysqli fixes

- When calling mysqli->prepare() and the statement failed for some reason move the errors from the statement object to the mysqli object
- Remove typing for real_escape_string and friends. In the end they all call mysql_real_escape_string which will handle the typing

Correctly handle invalidated POST data on upload path

DecodeRfc1867 was returning a data and length pointer that were being copied and saved for use with php://input.  In the case where AlwaysPopulateRawPostData is false, data will actually point to the last chunk received, but size will be the cumulative size of the post.  There's nothing meaningful that can be done with this data, just ignore it.

The data copy immediately prior to DecodeRfc1867 was unecessary when AlwaysPopulate was off, but for a silly realloc call in read_post.  Reworked this case to avoid the realloc/memcpy and just read directly from the network buffer.  While I was there, I corrected some integer types that could cause problems for POSTs > 2GB.

Add control of number of threads and running like PHPUnit

Add two options:

1. To specify the number of threads the runner should use run running a set
of framework tests.

2. To allow one to specify that framework tests should be run just like they
would be with normal PHPUnit. This has the effect, essentially, of setting
the Framework $parallel member to false at the command line. This setting
could cause the testing to stop in its tracks with a fatal, just like
PHPUnit stops too.

Pear actually is --as-phpunit by default (with the override of $parallel = false)
in its constructor, because it breaks otherwise.

Do not crash in mysql function if result is freed and used again

- If res->get() is NULL we need to return NULL
- Used here for example diffusion/FBCODE/browse/master/hphp/runtime/ext/mysql/ext_mysql.cpp;d2a96349bfb09871$750
- Then diffusion/FBCODE/browse/master/hphp/runtime/ext/mysql/ext_mysql.cpp;d2a96349bfb09871$761-762 we get the MYSQL_RES and call mysql_num_rows but if MYSQL_RES is null that crash.
