PECL in version information

Hello!

Here is the patch for including PECL functions in version information
in PHP documentation to achieve e.g.
"apd_breakpoint (PECL)" instead of
"apd_breakpoint (no version information, might be only in CVS)" or
"bzclose (PHP 4 >= 4.0.4, PHP 5, PECL)" instead of
"bzclose (PHP 4 >= 4.0.4, PHP 5)".

I tested it and it seems it works well.
