[RFC-PATCH] lib: add byteorder helpers for the aligned case

[Harvey Harrison <harvey.harrison@gmail.com>]

Some users know the pointer they are writing to are aligned,
rather than doing *(__le16 *)ptr = cpu_to_le16(val) add helpers
wrapping this up that have the same convention as put_unaligned_le/be.

Alan, as requested, I'm looking around a bit to see if there are actual
users for this.  But it does make a nice complement to the unaligned
versions.
