ZF-1282: Support for PHP's hash() for read/write control

Description

The Hash extension requires no external libraries and is enabled by default as of PHP 5.1.2. http://www.php.net/hash

I consider the Adler32 superior to CRC32 for the purposes needed by Zend_Cache.

If {{hash()}} was used, then a read/write control type of 'adler32' could work.

Comments

it seems a good idea... for 1.1.0
