Trim trailing whitespace in source code files

Trim trailing whitespace in source code files

Introduce get_properties_for() handler

This handler allows getting the object properties for a particular
purpose, such as array casting, serialization, etc.

Use zend_hash_find() instead of zend_hash_exists()

Replace ZEND_ACC_ANON_BOUND, ZEND_ACC_UNRESOLVED_PARENT and ZEND_ACC_UNRESOLVED_INTERFACES with single ZEND_ACC_LINKED.

Simplify __clone() visibility check (magic methods still don't respect ZEND_ACC_CHANGED).

Cleanup class linking

ZEND_DECLARE_CLASS, ZEND_DECLARE_INHERITED_CLASS and ZEND_DECLARE_INHERITED_CLASS_DELAYED don't need return value anymore.

Keep information about unresolved interfaces in zend_class_entry->interface_names.
Move interface implementation code into ZEND_DECLARE_*CLASS opcodes.
Remove ZEND_ADD_INTERFACE and ZEND_VER

Keep information about unresolved interfaces in zend_class_entry->interface_names.
Move interface implementation code into ZEND_DECLARE_*CLASS opcodes.
Remove ZEND_ADD_INTERFACE and ZEND_VERIFY_ABSTRACT_CLASS opcodes.

Replace zend_class_entry->traits by persistent zend_class_entry->trait_names.
Move trait binding code into ZEND_DECLARE_*CLASS opcodes.
Remove ZEND_ADD_TRIAIT and ZEND_BIND_TRAITS opcodes.

Change zend_lookup_class_ex() and zend_fetch_class_by_name() prototypes to accept optional lower-case class name as zend_string*, instead of zval*.

Stop using zend_function->reserved[] space.

Don't use second operand of BIND_STATIC instruction.

Removed dead code

Avoid hash lookups in BIND_STATIC and BIND_LEXICAL opcode handlers.
Encode static variable offset into opline->extended_value.

Added a note

Fixed bug #76752 (Crash in ZEND_COALESCE_SPEC_TMP_HANDLER - assertion in _get_zval_ptr_tmp failed).

Removed duplicate code. zend_fetch_dimension_address_LIST_w() was a copy of zend_fetch_dimension_address_W(), ZEND_FETCH_LIST_W_SPEC_CV_... a copy of ZEND_FETCH_DIM_W_SPEC_CV_...

Improved assignment to "next" element of array ($a[] = ...)

Use better check

Pack zend_constant.flags and zend_constant.module_number into reserved space inside zend_constant.value.

Encode parent class name as IS_CONST operand in DECLARE_INHERITED_CLASS and DECLARE_ANON_INHERITED_CLASS opcodes (eliminate FETCH_CLAS
S opcode).

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
use

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

Micro-optimization

Inline FETCH_CONST and DEFINED handlers into "hybrid" executor.
