This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
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.
gc_collect_white() will mark white nodes as black and add them as
garbage, but only if it's not buffered yet. The already buffered
roots are instead marked as garbage in gc_collect_roots() directly.
However, if gc_collect_white() marked a (buffered) root as black
through recursion, it would not subsequently be marked as garbage.
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
HT functions that modify the array now assert that rc=1. As we don't
respect this COW constraint everywhere, either for a good reason or
because fixing it would take more work, we provide an escape hatch
in the form of HT_ALLOW_COW_VIOLATION(ht). If this macro is called
assertions on this ht are disabled. The macro is a no-op in release
mode.
Under the special circumstance where a garbage collected objects bucket slot was not reused until the end of the script, we get access into freed memory...
No test added as it usually is valgrind-only, and only sometimes when the memory happens to have changed (i.e. (GC_FLAGS(obj) & IS_OBJ_FREE_CALLED) == 0), it actually *may* segfault
* PHP-5.6:
Prevent GC from changing zval or object 'color' before they are actually inserted into possible roots buffer.

Zend/zend_gc.c
Now each HashTable is also zend_array, so it's refcounted and may be a subject for Copy on Write
zend_array_dup() was changed to allocate and return HashTable, instead of taking preallocated HashTable as argument.
