[PATCH 1/2 (resend)] btrfs-progs: standardize tool source filenames

[Eric Sandeen <sandeen@redhat.com>]

For any btrfs-$FOO executable, rename the main source file from
$FOO.c to to btrfs-$FOO.c

This makes it slightly more obvious what's building what,
and allows us to write a default rule in the Makefile for
these tools.

(also add btrfs-calc-size to the list of objects to remove
on make clean)

vger ate my giant rename-files patch; here's the makefile bit, and
hopefully the rename-diffs at the end are something that git
knows how to apply?  TBH I've never tried that before.
