Hi all,

This patch-set attempts to address two open feature requests for Ext4Pkg
by adding ext2/3 support (id 3745) and moving crc16-ansi/crc32c to BaseLib (id 3871).

The previous patch-set regarding 3871 attempted to merge the different crc16 implementations
but failed because, contrary to what I thought, there are many, many different CRC16s which
are all slightly different. This one (plus the separate edk2 patch) attempts to just merge
CRC16-ANSI (confusingly, also known as CRC16) into BaseLib.

Since this patch set grew to be considerably different from the original, I didn't mark it
as v2 but rather a separate, new patch-set.

CC'ing the edk2-platforms stewards (as I cannot review my own code) and the CC's of the MdePkg
patch.
