Update ext/ldap sanity check (#13946)

The ldap_bind_s() has been deprecated and isn't used in the code in
favor of ldap_sasl_bind_s(). PHP falls back to deprecated
ldap_simple_bind_s() if for some reason ldap_sasl_bind_s() isn't
available and this check likewise.

Remove nsldap support

The newest version we're checking (libssldap50) seems to be about
15 years out of date. We could add support for libssldap60 (also
unmainted, but more recent), but given how nobody has expressed any
interest in this, I'm going ahead and dropping this code.

Fix detection of gmp on clang

Split the default and custom path case. If the default is used,
assume that the library must be on the default include and lib path.
Only check that the version is appropriate.

Something similar is needed for ldap, but the checking code is much
more complex there, so I'm only adding a workaround for now.

Sync AC_CHECK_SIZEOF m4 macro calls

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.

Removed ldap_sort and LDAP_DEPRECATED build flag

ldap_sort was deprecated in PHP7, it is now removed.
This allows removing the LDAP_DEPRECATED flag when building against
openldap.

Replace obsolete AC_TRY_FOO with AC_FOO_IFELSE

Replace obsolete AC_TRY_FOO with AC_FOO_IFELSE

Autoconf 2.50 released in 2001 made several macros obsolete including
the AC_TRY_RUN, AC_TRY_COMPILE and AC_TRY_LINK:
http://git.savannah.gnu.org/cgit/autoconf.git/tree/ChangeLog.2

These macros should be replaced with the current AC_FOO_IFELSE instead:
- AC_TRY_RUN with AC_RUN_IFELSE and AC_LANG_SOURCE
- AC_TRY_LINK with AC_LINK_IFELSE and AC_LANG_PROGRAM
- AC_TRY_COMPILE with AC_COMPILE_IFELSE and AC_LANG_PROGRAM

PHP 5.4 to 7.1 require Autoconf 2.59+ version, PHP 7.2 and above require
2.64+ version, and the PHP 7.2 phpize script requires 2.59+ version which
are all greater than above mentioned 2.50 version therefore systems
should be well supported by now.

This patch was created with the help of autoupdate script:

Remove unused Git attributes ident

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.
