Header `<errno.h>` is part of the standard C89 headers [1] and on
current systems checking is not need anymore since PHP requires at
least C89. This is noted also by Autoconf itself in the docs and
code [2].
The Autoconf check defined the `HAVE_ERRNO_H` symbol when building PHP
with sockets extension or fpm sapi. This symbol is not utilized across
the PHP source code except in the current version of bundled GD library
which has worked ok so far also with sockets extension or fpm sapi
disabled anyway.

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:
autoupdate <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.
AI_IDN is not supported by all C libraries (uClibc, musl), so make it
optional, like AI_ALL.

This introduces two new functions:
int socket_recvmsg(resource $socket, array &$msghdr, int $flags)
int socket_sendmsg(resource $socket, array $msghdr, int $flags)
The arrays representing struct msghdr follow the native counterpart
closely: structs are mapped to arrays, fields to array elements whose
key is the name of the field without the prefix (e.g. "name" instead
of "msg_name") and array are mapped to sequential numeric PHP arrays.
Right now the only type of ancillary data supported is fot the
level/type pair IPPROTO_IPV6/IPV6_PKTINFO.
I also refactored out the name resolution functions and made
sockets_strerror() a global function.
because it does not include <sys/socket.h> which is necessary
for the definition of struct msghdr. This include file is not
part of ac_includes_default.
Regardless, AC_CHECK_MEMBER is a autoconf-2.5x macro and thus we
expand it here for 2.13 compatibility.
on most varieties of Linux, and should hopefully fix at least 3 of the
compile errors that were discovered). Also modified read() slightly
to take an optional parameter as to whether the data was binary or
text so it wouldn't stop reading on a newline or null byte received.
