On x86_64 glibc memrchr() uses SSE/AVX CPU extensions and works much
faster then naive loop. On x86 32-bit we still use inlined version.
memrchr() is a GNU extension. Its prototype becomes available when
<string.h> is included with defined _GNU_SOURCE macro. Previously, we
defined it in "php_config.h", but some sources may include <string.h>
befire it. To avod mess we also pass -D_GNU_SOURCE to C compiler.

We need to verify that the `result_size` is not larger than our buffer,
and also should make sure that the `len` which is passed to
`isc_vax_integer()` has a permissible value; otherwise we bail out.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
Instead of requiring the type to be determined in advance by the
describer function and then requiring get_col to return a buffer
of appropriate type, allow get_col to return an arbitrary zval.
See UPGRADING.INTERNALS for a more detailed description of the
change.
This makes the result fetching simpler, more efficient and more
flexible. The general possibility already existed via the special
PDO_PARAM_ZVAL type, but the usage was very inconvenient and/or
inefficient. Now it's possible to easily implement behavior like
"return int if it fits, otherwise string" and to avoid any kind
of complex management of temporary buffers.
This also fixes bug #40913 (our second highest voted bug of all
time, for some reason). PARAM_LOB result bindings will now
consistently return a stream resource, independently of the used
database driver.
I've tried my best to update all PDO drivers for this change, but
some of the changes may be broken, as I cannot test or even build
some of these drivers (in particular PDO dblib and PDO oci).
Fixes are appreciated -- a working CI setup would be even more
appreciated ;)
Add a get_gc method that can be implemented by drivers, which can
be used to add additional zvals to the GC buffer.
Implement GC support for PDO SQLite callbacks in particular.
Closes GH-6262.
This patch fixes some problems with preprocessing SQL queries.
* The new algorithm takes into account single-line and multi-line
comments and ignores the ":" and "?" Parameter markers in them.
* The algorithm allows the EXECUTE BLOCK statement to be processed
correctly. For this statement, it is necessary to search for
parameter markers between EXECUTE BLOCK and AS, the rest should be
left as is.
The SQL preprocessing code has been ported from Firebird to handle
EXECUTE STATEMENT.
Closes GH-4920.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
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.
