The `<time.h>` header file is part of the standard C89 headers [1] and
on current systems can be included unconditionally.
Since PHP requires at least C89 or greater, the `HAVE_TIME_H` symbol
defined by Autoconf in ext/pdo_sqlite/config.m4 [2] can be ommitted and
simplifed.
Additionally, since PHP didn't define `HAVE_TIME_H` prior in the
configure.ac the occurrence of this symbol in cli can be removed.

The FormatMessage API needs to LocalFree the delivered error messages.
In cases where messages are delivered in non ASCII compatible encoding,
the messages might be unreadable. This aligns the error message encoding
with the encoding settings in PHP, the focus is UTF-8 as default.
Initialize error buffer
Avoid code duplication
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.

This patch makes several scripts and PHP development tools files
executable and adds more proper shebangs to the PHP scripts.
The `#!/usr/bin/env php` shebang provides running the script via
`./script.php` and uses env to find PHP script location on the system.
At the same time it still provides running the script with a user
defined PHP location using `php script.php`.
This change results in using the same buffer for multiple
stdio events which should fix inconsistencies of handling
messages that are not ended with a new line and possibly
very long messages that are split to multiple events.
Send phpdbg.1 man page through configure replacements
Update phpdbg.1 man page to include all options
Fixes formatting to be more consistent with php.1
Fix paragraph whitespace and ignore phpdbg.1
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.
