* Simplified PHP testing scripts.
- allow them to be run from any directory.
- remove "VERSION" arg, we can get PHP from $PATH.
* Added a few places I missed.
* Removed redundant "cd `dirname $0`".
Also replaced all backticks with $(), for consistency.
* Add scripts to test multirequest
* chmod ug+x multirequest.sh
* Add continuous test
* Compile c extension
* Class entry is obsolete in the second request
1) Needes to use class name in persistent map
2) Invalidate class entry stored in descriptor
* Add new files to dist
* Fix compile_extension
* Cleanup outputs for phpize
