Adding this table will make extending btrfs-progs with new checksum types
easier.
Also add accessor functions to access the table fields.

Update the checksumming API to be able to cope with more checksum types
than just CRC32C. The finalization call is merged into btrfs_csum_data.
There are some fixme's and asserts added that need to be resolved.

In preparation to supporting new checksum algorithm pass the checksum type
to btrfs_csum_data/btrfs_csum_final, this allows us to encapsulate any
differences in processing into the respective functions

Pass pointer to a generic buffer instead of fixed size that crc32c
currently uses.

For options that do not have the long description, the empty string is
required to mark where the options start. Some commands were missing
that.
