Add system ID entropy API

The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart.

Remove unused build checks

- yp_get_default_domain was part of ext/yp
- functions checks produce HAVE_function_name symbols. These checks are
currently not used in php-src neither in the extensions out there.
- Removed symbols because they are not used in the code:
- HAVE_GCVT
- HAVE_PUTENV
- HAVE_PUTENV
- HAVE_SETVBUF
- HAVE_TEMPNAM
- HAVE_SIN (sin is also defined in C89 standard)
- HAVE_SETSOCKOPT
- HAVE_LOCKF
- HAVE_ISASCII
- HAVE_YP_GET_DEFAULT_DOMAIN (and other yp extension related unused checks)
- HAVE_LINK
- HAVE_USLEEP is already defined in Windows configuration header
- HAVE_LIBBIND has not been used in php-src for a while anymore
- HAVE_GETHOSTNAME is duplicated in Windows configuration header

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.

Sync leading and final newlines in source code files

This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

Sync leading and final newlines in source code files

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.

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.
