[RFC,0/2] btrfs-progs: provide command to dump checksums

Message

Provide a command to dump checksums from 'btrfs inspect-internal'. This then
does a lookup for the given file's extents and walks the csum tree printing
all checksums of an extent.

This is marked as an RFC because up to now I've only tested it on simple files
created with 'xfs_io -f -c "pwrite 0 $SIZE"', but like to hear some feedback.

It is also missing some tests to check implementation and provide regression tests
for eventual bugs.

It is also available on github @ https://github.com/morbidrsa/btrfs-progs/tree/inspect-csums
