Patches for Review

Hey all, I had messaged about these patches before, but with the 5.4 release process happening I think it slipped through the cracks. I have 3 patches that are ready for inclusion... https://bugs.php.net/bug.php?id=60813 Adding a new hash_pbkdf2() function to allow for a C level implementation of the PKCS5 recomended password key stretching algorithm. https://bugs.php.net/bug.php?id=60789 Bringing pow() inline with docs in that it will attempt to return an integer (by casting one or more of the arguments to int) if possible. This fixes a precision loss that can occur with float arguments that are exactly integers on 64 bit platforms. https://bugs.php.net/bug.php?id=60596 A little code-cleanup to remove a superfluous if statement in a switch in the spl_offset_convert_to_long function... If anyone can commit these, if I can be granted the Karma to commit them. of if anyone can comment as to why they should not be committed, that would be great. Thanks, Anthony
