Resources used as array keys are generally handled by throwing a
notice and converting the resource to the resource handle. The only
exception is the [$resource => null] syntax, where this was treated
as an illegal offset type instead. However, this also only happened
for VM evaluations, the AST evaluator did handle resources correctly.

Similar to what is done for socket read/write errors.

If a string var_dump contains a wildcard, also make the length a
wildcard.

Instead of patching configuration headers template generated by
the given tools - autoheader, this moves patching these symbols to
the configure step before creating and invoking the config.status
and before the configuration header file is generated from the
patched template.

- Variables php_abs_top_srcdir php_abs_top_builddir are no longer used.

Closes GH-4378

This makes the script a bit more portable when used on systems with
different LC_ALL and LANG settings.

This enhances the makidst script:
- integrate both snapshot and makedist scripts together
- add help and options
- generated files are created in the php-src repository directly
- other minor enhancemenets such as CS fixes
- functionality moved from the Makefile to only shell script
- Add missed patching of the Zend Parsers to the main build step
- Add all *.tmp files to gitignore

Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
  favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now

The vcsclean script is really only a wrapper for a git clean command.
Developers should use the more proper and clear native Git command
directly instead:
`git clean -Xfd`
