PHP RFC: Consistent Function Names

Userland implementation of PHP RFC: Consistent Function Names. It creates aliases with more consistent names.

There are many functions that named before naming standard in CODING_STANDARDS. Therefore, PHP has function names like phpversion() and htmlspecialchars().

We have many function names that comply IEEE 1003.1 standard names. IEEE 1003.1 is also well established names, but it has different naming. IEEE 1003.1 names can be use as aliases.

Without cleanups, PHP may have inconsistent API names even if PHP has new APIs for the same purpose because we care compatibility a lot. Unless we have standard confirming function names at some point, we may keep inconsistent function names forever and never have consistent function names.

Please read the RCF for more information: https://wiki.php.net/rfc/consistent_function_names
