Simplify checking of *nix build tools

The buildmk.stamp file has been created by the *nix build checking step
to run the check step only once. Instead of poluting the project root
directory, the stamp file can be also omitted. Performance difference is
very minimal to not justify having the stamp check at all today anymore.

This patch integrates the buildcheck.sh to buildconf script directly.

Move acinclude.m4 to build/php.m4

The acinclude.m4 file is in a usual Autotools build processed with
Automake's aclocal tool. Since PHP currently doesn't use Automake and
aclocal this file can be moved into the build directory. PHP build
system currently generates a combined aclocal.m4 file that Autoconf
can processes automatically.

However, a newer practice is writing all local macros in separate
dedicated files prefixed with package name, in PHP's case PHP_MACRO_NAME
and putting them in a common `m4` directory. PHP uses currently `build`
directory for this purpose.

Name `php.m4` probably most resembles such file for PHP's case.

PHP manually created the aclocal.m4 file from acinclude.m4 and
build/libtool.m4. Which is also not a particularly good practice [1], so
this patch also removes the generated alocal.m4 usage and uses
m4_include() calls manually in the configure.ac and phpize.m4 files
manually.

- sort order is not important but can be alphabetical
- list of *.m4 files prerequisites for configure script generation
updated
- Moving m4_include() before AC_INIT also removes all comments starting
with hash character (`#`) in the included files.

Simplify generated_lists generation

The `generated_lists` file is generated as a helper for build related
Makefile to include a list of *.m4 files prerequisites. When some of
these *.m4 files change, the configure script is regenerated when
buildconf is run. This can be simplified using dynamic environment
variable passed to the Makefile directly so it avoids another file from
being generated in the project root directory and shipping it with the
PHP release or creating a dedicated gitignore rule.

This is portable across all POSIX compatible makes So this patch
includes GNU Make, and everybody elses' make derivative support.

Remove lexer files generated by RE2C

This patch removes generated lexer files by re2c during the build
process so they are not tracked by Git yet can be still shipped when
PHP is released. The genfiles script additionally provides generation
of these lexer files when creating a release of the PHP source code.

The genfiles script refactorings:
- added file header
- echoing steps instead of comments
- cleaning only lines starting with `#line`
- eval removed in favor of direct executed commands
- the debug mode `set -x` removed
- script can be called from any path
- improved comments

Remove ext/json parser files generated by bison

The parser files for ext/json are generated by bison from the *.y file.
Parser files in Zend and sapi/phpdbg already follow such approach of
these files being ignored from tracking in the Git repository and they
are shipped via the release packages later on. This way the end users
still don't need to have bison dependency installed to install PHP.

The genfiles script was refactored to generate the ext/json parser and
lexer files.

Normalize .gitignore

Changes:
- Added introductory paragraph to explain the file for newcomers and
where to ignore local editor configurations as a common practice
when using Git.
- Patterns organized into several main context sections for a better
overview of the php-src directory structure and which files get
generated where.
- Added comments describing reasons for ignoring particular file(s).
- Patterns normalized according to Git ignore blob patterns. Absolute
paths are different than relative paths and similar fixes.
- Folders patterns have appended ending slash for readability to
distinguish them from files.

Removed ignore patterns:
- Removed `sapi/phpdbg/build` pattern since it doesn't seem to be
relevant anymore in the php-src repository.
- The `acconfig.h` pattern removed in favor of the more recent Autoconf
versions.
- Removed patterns for `.FBCIndex` `.FBCLockFolder` folders. These were
generated on old Mac OS systems [1] using the Sherlock [2] software
and can be today ignored using a global gitignore file if needed.
Newer macOS systems don't generate these anymore.
- Removed `php_version.h` pattern since the `main/php_version.h` file is
tracked by Git.
- Removed `*.mk` pattern since few *.mk files are tracked by Git and new
ones aren't generated during build process.
- Removed `**/tests/**/*.txt` pattern. This has been refactored via
595a395cb911a4ef54cbaf11cd0056d38316c87c and current tests also clean
the generated `*.txt` files as soon as they are executed. Since there
are several `*.txt` files in the repository tracked by Git already and
renaming them would be counter productive so the pattern is now removed.
In case there will be a need to adjust it, we can rename the generated
`*.txt` into something else instead (ideally into `*.tmp`) to not
conflict with already tracked `*.txt` files in tests.
- Removed `ext/*/scan_makefile_in.awk` and `scan_makefile_in.awk` patterns
since these are already included in the `/ext/*/build/` pattern.
- Removed the `/ext/*/libs.mk` pattern since these auxilary Makefiles
have been used in previous build system and made obsolete via the commit
9d9d39a0de3bec962c343051011f5a2ed7d7b242.
- Removed pattern for configuration header `ext/pdo_sqlite/sqlite3.h` since
it is not generated anymore in the current code.
- Removed `main/streams/build-defs.h` pattern since this file is not
generated.
- Removed `test.php3` pattern. These don't seem to be present in the current
PHP source code nor used since PHP 3.
- Removed `/ext/oci8/tests/*.vglog` pattern since the tests don't seem to
produce these files.
- Removed pattern for Visual Studio's `*.ncb` files. Since the Visual
Studio 2010 they are no longer used.
- Removed `ext/sqlite3/tests/phpsql*` pattern. It was part of the `ext/sqlite/tests`.
- Removed `shlibtool` pattern since the shlibtool file is not generated
anymore. It was once part of the libtool usage and customized naming
used in the previous build system in Makefiles. Such naming was later
removed and only libtool was used.
- Removed `meta_ccld` pattern since it is no longer relevant via
a5b55416f4bf48e475b30bb86b120c83efccca53
- Pattern `meta_cc` has been removed via e5176fe60a9ffbe211ee016acdcddb18118e4487.
- Pattern `dynlib.m4` removed since the file is no longer generated via
9d9d39a0de3bec962c343051011f5a2ed7d7b242
- Pattern `debug.log` removed since the Autoconf Macro PHP_DEBUG_MACRO
is not called anymore and this file not generated anymore.
- Pattern `results.txt` removed. It was once part of the logging results
of test files by Netware and previous Windows builds.
- Removed `_libs` pattern in favor of only `.libs`. These directories
were once generated by Automake and Libtool on systems that didn't
support the dot folder `.libs` (MS-DOS).
- Removed `*.opt` pattern since it was used by Visual Studio 6. Later
versions of Visual Studio don't use these anymore.
- Removed `*.plg` pattern. It was build log generated by Visual Studio 6.
- Removed `core` pattern since it was probably related to commit
fd7153b0f3047e6a96344dc3b4ca2632d5acc898 and is today not used.
- Removed ˙*.˙, ˙diff`, and ˙*.tgz` patterns since they don't seem to be
generated in the current code on the first glance. In case these will be
one day required to ignore again, they can be simply added back again.
- Removed Emacs specific interlock files pattern `.#*`. The number of
editors and IDEs specific files is very big. Emacs editors also produce
some other files such as `#*#` for autosave feature, which were previously
not ignored. To fully and properly support all additional patterns these
could be added to .gitignore files. A much more sustainable and better
practice is to use a global gitignore file on the local system or the
`.git/info/exclude` per repository basis for these in particular.

Added patterns:
- Added new pattern for `*.obj` standard object files in the Windows
section. These are generated by Visual Studio.
- Added `/ext/*/run-tests.php` patterns for extensions.
- Reversed patterns for particular tracked `/win32/build/Makefile`, `config.h`
files and `.patch` files.
- Added patterns for generated dtrace files `/ext/oci8/oci8_dtrace_gen.h`

Other changes:
- All `conftest*` patterns merged into a single one.
- Pattern `*.mem` made more specific where the memory check files get
generated by `run-tests.php -m`, i.e. `**/tests/**/*.mem`.
- Fixed `/Zend/zend_dtrace_gen.h.bak` `hbak` typo.

The `mkdep.awk` file was part of the previous *nix build system and was

Newer build system was done via 9d9d39a0de3bec962c343051011f5a2ed7d7b242
and outdated files removed via 22815419f8c5da902971d3aa12f2cbfcc3b41aff
so the current file in the PHP source code is not used anymore.

Additionally, the *.slo files were processed by this file. The *.slo
files also used to be generated by older libtool so today, these don't
get generated anymore.
