ext/filter, custom decimal separator, supports leading 0, regexp

I'll have to review it.

If we're going to make it the default way of handling user data,
then it makes sense to implement it as flexible as possible, and
regex stuff should be compatible with ext/pcre.

Hello,
Due to the success on my precedent post, I try again to get some
comments on my precedent patch and some new things I need in ext/
filer.
This patch adds or changes the following things:

• regexp uses functions (ext/pcre)
  • 100% compatible with preg_* functions
  • Use of expression caches and other (faster)
  • Regexp tests now work
• rewrite the filter_float
  • support custom decimal separator. Let the developer decides
    which separator to use, the default is not changed
  • slightly faster than the old implementation (and with the new
    features)
    The patch:

    Some examples:

    Any ideas or comments are welcome,
    --Pierre
