Fix leak in += with arrays

- Fix bug #2364.
I haven't checked all of the conversion macros yet but there's a change
there are more such bugs there.

- Fix leak when decrementing strings which actually are longs.

Revert the IS_RESOURCE patch. It had some unintended behavior.

Release resources when converting to other types (fix Thies's reported problem)

- Fixed a memory leak when using assignment-op operators with lvalue of type
string (or array/object)

* Add an API macro users can use to ensure an array member can be modifed
before they modify it.
* Fix a bug and remove redundant code in convert_to_long() (booleans and
resources wer

before they modify it.
* Fix a bug and remove redundant code in convert_to_long() (booleans and
resources weren't changing their types

- Get rid of C++ comments

0.91 update

License update

- Fix for boolean convert to number

Step 4:
Move to a 7-bit counter (not fully implemented yet)

Step 2:
Rename is_ref to EA

Make convert_to_string() regard false as "" instead of "0"

* Make the memory leak reporting code much better with repeats
* Remove useless variables

* Fix concatenation of arrays (it was PHP 3.0 style, copying zval's instead
of zval *, and it wasn't using reference counting)
* Fix a memory leak in static array()'s with textual indices

* added zend_binary_strcasecmp()

Make the concatenation operator use make_printable as well

Now THAT's an annoying bug.

- Fix the static array() initializing

Minor updates (mostly __declspec() stuff)

Support overwrite mode in zend_hash_merge()

The last fix was wrong

Another operators fix

boolean comparison didn't work with smaller-than and greater-than, something that
fucked up berber's site a bit. fixed.
