First commit of re-structuring phase one. We have started using automake in
sub-directories and started to move extension code into ext/<name>. For now,
I have moved the "standard" extension (which is quite a mix of everything
right now) and the GD extension into their own subdirs in ext/.
The configure script now also runs configure in the libzend directory
automatically and makes sure php4 and libzend use the same config.cache file.
To avoid running configure in libzend, use the --no-recursion option.
"make" in php4 also builds libzend now.
The Apache module doesn't compile right now, but a fix for that is
coming up.

updated GD from php3 repository, using it as a test extension for the new
directory structure

- Make the memory leak message print PHP4.

- one more place which seems to have needed fixing. I don't have time to look
more into it. I hope we don't have anymore places which need fixing.

- Should fix the pass by reference problem. This happened because we moved
start from arg 1 now and not arg 0. There might be more places which need fixing
like in the executor but the bug

- Should fix the pass by reference problem. This happened because we moved
start from arg 1 now and not arg 0. There might be more places which need fixing
like in the executor but the bug seems OK now.

Compile fix

-Tiny patches

Better detection

Move Ai stuff before get_zval_*(), like Andi suggested. Fixes Sascha's huge
memory leak

- Fix various memory leaks.

Refcount bugfix

* Optimize argument_stack top lookup
* Fix a nasty bug in zend_ptr_stack_clean()

Remove unnecessary stack

off by one

Minor optimization

Make functions that don't take arguments somewhat happier:)

This should take care of "this" for user-defined functions. It wasn't yet working
for built-in functions anyway, this one is coming soon.

NULL's should remain NULLs (at least in strings)

Destroy the resource list after destroying the symbol table, otherwise the
auto-destructor for resources are run when the resource list is no longer valid

This patch is a go. Not fully optimized yet, but working properly.
Prepatch tagged as BEFORE_STACK_PATCH.

Minor fixes:
missing zval_copy_ctor()
messed up AiCount fix

tolerate uninitialized ini settings in php_ini_{long,double,string}()

This should help in keeping PHP4 up to date
