tcache.flush mallctl was renamed in jemalloc3, update

Since upgrading to jemalloc3 hhvm hasn't actually been flushing
the tcache during idle times.  That bug has also been masking a bug in
which we still try to purge thread.arena despite overriding jemalloc
narenas to be 1, so I have removed that code as well.

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.

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.
