Add stdlib::crc32

[jcpunk]

CRC32 is a handy way to run trivial checks against values. Unlike the SHA hashing series generating collisions is fairly trivial which makes it useful for describing secret data in a public manner. For example, "Is you app using secret 18fbd270 or 7d5469f0" cannot possibly be used to reconstruct the secret but does permit concrete conversation about the secret itself. This can be further useful when the developers do not have direct access to the secret in question.

It is also handy for establishing an application specific shared seed across multiple hosts, for establishing trivial user sharding, or other applications where uniqueness is not actually an asset.

These results were generated with Rangefinder, a tool that helps predict the downstream impact of breaking changes to elements used in Puppet modules. You can run this on the command line to get a full report.

Exact matches are those that we can positively identify via namespace and the declaring modules' metadata. Non-namespaced items, such as Puppet 3.x functions, will always be reported as near matches only.
