Fail early in *nix configuration build script

Adding two exit early safeguards in the *nix configuration build script:

1) Given the initial cd into the build tree fails (the project root),
the `buildconf` script exits with non-zero status (failure).
2) Given the grep command does not exist or `configure.ac` AC_INIT [1]
expectations are unmet, the buildconf script exits non-zero.

Additionally quoting the pathname to cd into and the empty CD_PATH
parameter for portability, also for systems that are using a
non-portable pathname [2] for the build tree.

The initial CD safeguard has been applied to the `buildconf` and
four more scripts:

- build/genif.sh
- scripts/dev/credits
- scripts/dev/genfiles
- scripts/dev/makedist

Rationale:

Cd-ing into the project root should always prematurely exit w/ FAILURE
as a required precondition for its invocation has not been met. This
should never go unnoticed as it always requires user intervention.

Similar and more specifically to the PHP build on *nix systems, the
grep command is required early to obtain the `php_extra_version` from
configure.ac. Previously, if the grep command is missing (or failing
due to not matching the line with the AC_INIT macro [1]), the internal
dev parameter would always be zero (0) which can easily result in the
situation that the configure script is not being rebuilt. This is
cumbersome as the rebuild of a configure script is more likely required
with checked-out dev versions under change rather than an already
properly set-up build environment on a dedicated build or release
system. Missing the fact that either the grep utility is missing or
the expectation of having the AC_INIT macro in configure.ac is unmet
should never go unnoticed as it always requires user intervention.

Refactor PHP_PROG_BISON and PHP_PROG_RE2C

This patch refactors these macros to also checks for the required given
versions of bison and re2c.

Refactor PHP_PROG_BISON and PHP_PROG_RE2C

This patch refactors these macros to also checks for the required given
versions of bison and re2c.

- PHP_PROG_RE2C and PHP_PROG_BISON take optional args - minmimum version
required, and bison also excluded versions.
- Instead of caching values this uses manual checking and messaging
outputs.
- It looks like the minimum version of RE2C 0.13.4 is working ok so far.

The genfiles script improvements:
- Add make override in genfiles
- Move checkings from makedist to genfiles
- Refactored output messages
- Various minor enhancements

Upgrade deprecated directives and use non-posix bison

With Bison 3.0 some directives are deprecated:
- %name-prefix "x" should be %define api.prefix {x}
- %error-verbose should be %define parse.error verbose

Bison 3.3 also started emiting more warnings and since PHP souce parsers
are not POSIX compliant this patch fixes this as pointed out via

Move distribution generator script to scripts/dev

The more proper place for shell scripts dedicated for development, and
releasing PHP should be the scripts/dev directory. Having a cleaner root
project directory helps find the main README.md and files relevant to
install PHP.

These scripts are also used by the release managers mostly who create
release packages and aren't used often by the majority of developers
working on and installing PHP.
