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.
Do not create an array with two keys for every element. That's a
huge waste of memory. Instead we allocate a two-element structure.
This reduces memory usage and avoids having to perform hashtable
lookups to get at the data and priority.
The only thing this might impact negatively is the non-default
EXTR_BOTH mode, in which case the array has to be created anyway.
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

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.
Using ecalloc() to create objects is expensive, because the
dynamic-size memset() is unreasonably slow. Make sure we only
zero the main object structure with known size, as the properties
are intialized separately anyway.
Technically we do not need to zero the embedded zend_object
structure either, but as long as the memset argument is constant,
a couple more bytes don't really matter.
conver_to_* functions now accept REFERENCE values, which will be
unwrapped before performing the usual conversion. This is consistent
with convert_scalar_to_number and matches the expected behavior in
a couple random use-sites I checked.
Also includes a couple fixes/cleanups elsewhere and two tests for
cases that previously didn't work (though the reference issue existed
all over the place).
ctor/dtor are now no longer called for insert/delete_top operations,
only for cloning and freeing of the object. Otherwise elements will
have a minimum rc of 2 and GC won't be able to free them.
Instead of using the array apply count on the debug_info array, use
the object apply count for recursion detection when dumping. This
handles recursion in a more generic way and does not require each
debug_info handler to deal with this.
This allows returning a temporary debug_info array, instead of
having to store it in the object (thus delaying destruction of the
values).
Switch SPL debug_info handlers to use a temporary array.
