Mark error and exception functions as "cold" (Matt's idea)

Reimplemented ability to get debug info (C source file and line number) in phpdbg without hacks and ABI breaks.

improve ZEND_TLS declaration even more and move it to the better place

use better name

add ZEND_THREAD specifier

Cleanup shutdown, enable proper memory leak displaying
phpdbg should not memory leak...

fix two clang errors on Windows

Ignore getcwd return in zend_compile

To do this move the php_ignore_value macro to ZEND_IGNORE_VALUE.

Optimize out usless conditions used by specializer

Better check for __builtin_constant_p() availability

Also try __has_builtin() where builtins are used

Use weak function for fcgi_log

Drop old VC support in Zend Engine, this also kills the remaining MessageBox fix for Windows 9x that Anatol changed a while back

Introduce ZEND_ASSUME() macro to help optimizing code.
Reuse ZEND_ASSERT() conditions for optimization.

Move check for __builtin_expect to configure

This allows __builtin_expect to be used more accurately

This should fix compilation on OSX (bug #68987 Failed to compile zend.c with gcc-4.9.2)

bump year

trailing whitespace removal

added comment

do portable socket checks

also introduced a portable macro for that

basic clang compatibility on windows

improved the ZEND_FASTCALL convention for vc12+

generalized the case with secure memory zeroing

Clang attributes support

Moved some definitions from zend.h into more suitable header files
