PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
While running these on HHVM I've run into a lot of parallelism issues.
I'm backporting all the fixes I had to do in
https://github.com/facebook/hiphop-php/blob/master/hphp/tools/import_zend_test.py#L650
to php core.
Most of these changes were just filenames that were shared between
tests, but I did more surgery on the fixed ports. I can apreciate port
31337 as much as the next nerd, but random ports are better for tests.
