Bump versions for 7.2.18

Prepare main branch for PHP 7.3.5

Sync AC_CHECK_SIZEOF m4 macro calls

- AC_CHECK_SIZEOF is now called mostly only in PHP_CHECK_STDINT_TYPES()
macro except for some parts checking for the 32 or 64 bit architecture.

Sync AC_CHECK_SIZEOF m4 macro calls

- AC_CHECK_SIZEOF is now called mostly only in PHP_CHECK_STDINT_TYPES()
macro except for some parts checking for the 32 or 64 bit architecture.
- SIZEOF_CHAR removed since it is always 1
- ZEND_BIN_ID is now of a more logical pattern `BIN_48888` on 64bit
architectures and `BIN_44444` on 32bit instead of literal string
`BIN_SIZEOF_CHAR48888` on 64bit and `BIN_SIZEOF_CHAR44444` on 32bit.
The unneeded SIZEOF_CHAR part has been removed.
- XMLRPC_TYPE_CHECKS removed
- The `long long int` is the same as `long long` and redundant checks
removed accordingly.
- Removed PHP_CHECK_64BIT macro. Checking if current platform is 64bit
or not can be also done simply by using a check of the long type on
place. This removes redundant m4 macro PHP_CHECK_64BIT.

Remove legacy AC_CHECK_TYPE calls for uint and ulong

The AC_CHECK_TYPE was refactored in more recent versions of Autoconf
and the call with two arguments is obsolete and not recommended anymore.

This patch also refactors some leftovers of using ulong and uint which
are not standard nor common usages of types in C.

The ulong can be used as zend_ulong and uint usage is actually
`unsigned int`.

The usage of HAVE_ULONG removed since it is not used in current code
base.

Legacy edgecase for some legacy HPUX systems removed:
- sys/stream.h header is not checked and the HAVE_SYS_STREAM_H is
not defined with current build system.

- flags are unsigned int
- max_allowed_packet changed to unsigned int

Move Makefile.global and Makefile.gcov to build directory

Replace PHP_TM_GMTOFF with AC_CHECK_MEMBERS

Changes:
- PHP_TM_GMTOFF removed
- HAVE_TM_GMTOFF replaced with HAVE_STRUCT_TM_TM_GMTOFF
- HAVE_TM_ZONE replaced with HAVE_STRUCT_TM_TM_ZONE
- HAVE_TZNAME removed

The PHP_TM_GMTOFF macro can be replaced with Autoconf's AC_CHECK_MEMBERS
that defines the HAVE_STRUCT_TM_TM_GMTOFF symbol instead of the
HAVE_TM_ZONE.

The HAVE_TZNAME symbol is not used in current code. The obsolete
HAVE_TM_ZONE symbol has been replaced with more proper
HAVE_STRUCT_TM_TM_ZONE. These are defined by the AC_STRUCT_TIMEZONE
macro.

Remove obsolescent AC_HEADER_STDC and memcpy check

Autoconf 2.59d (released in 2006) [1] started promoting several macros
as not relevant for newer systems anymore, including the `AC_HEADER_STDC`.

This macro checks if given system has C89 compliant header files such
as `<string.h>`, `<stdlib.h>`, `<stdarg.h>`, `<float.h>`,... and defines
the `STDC_HEADERS` symbol [2]. Case is that current systems should be
well supported with at least C89 standard headers [3].

Given headers are still additionally checked with the `AC_PROG_CC`
macro, yet not needed anyway.

Additionally, the HAVE_MEMCPY check has been removed. The memcpy
function is standardized by C89 and later.

Remove unused PHP_AC_BROKEN_SNPRINTF m4 macro

The snprintf function is part of the C99 standard and newer systems in
most cases all support it as defined in the standard. However, some old
Windows and HP-UX systems the function behaves differently. These checks
were also removed and PHP now uses a replacement for the snprintf
function. With gradual transition to C99 usage as a minimum requirement,
it will also be able to be replaced to system's snprintf function
directly.

Additionally in this context the unused HAVE_VSNPRINTF and check for
vsnprintf have been removed. PHP uses its own vsnprintf implementation
for now until more reliable C99 compliant function can be used from the
C libraries.

Remove unused PHP_AC_BROKEN_SPRINTF and AC_ZEND_BROKEN_SPRINTF

The sprintf function has been normalized to php_sprintf via
61364b5bb172fa512c871b795c2613b1b587e4cd.

This patch removes the checks to make a custom sprintf function

The ZEND_BROKEN_SPRINTF has been removed and the
hardcoded #define zend_sprintf sprintf is used.

The php_sprintf and zend_sprintf are now symbols to sprintf.

This patch now removes the custom PHP definitions of the php_sprintf and
zend_sprintf functions in favor of the C99 sprintf which is also
standardized in C89 already. Once, on some systems sprintf didn't behave
in same way.
