This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

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>

Since PHP 5.3 flex lexer has been replaced with re2c. Commit
0f9e2b1753 made PHP_PROG_LEX macro still
available for BC.
In commit df6bd506d4 it was updated. Since
this macro is entirely not used in PHP source code anymore from PHP 5.3
and up, this patch removes it together with some old traces of warnings
suppression and comments.
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.
configure.ac was introduced in 2001 with automake-1.15 and autoconf-2.50
to replace the file named configure.in.
Autotools is preparing to remove configure.in in Automake 2.0.
All new software should be using configure.ac.
This also fixes Bug #69770 where extensions are creating configure.in

The following new/revived shared modules are available now:
... MySQL (*)
... PCRE (*)
... Session
... SWF
(*) capable of using bundled library or external library
All changes:
The m4 macro PHP_EXTENSION was revamped. Uses LIB_BUILD now.
This effectively means that all extensions have to use dynlib.
ext/mysql/config.m4 was revamped.
Uses LIB_BUILD for building bundled library.
ext/pcre/config.m4 was revamped.
Uses LIB_BUILD for building bundled library.
ext/ext_skel was changed to reflect that more modules should be
compileable as shared module.
ext/Makefile.in has been simplified enormously.
Dependencies are now stored in the build tree.
Empty dependencies are not generated by buildconf anymore. They
are now dynamically created during the build process.
Implicit rules for .S were removed.
The NO_RECURSION feature was removed.
"libs.mk" has been added to all cvsignore files in ext.
