btrfs-progs: drop weird indirections & dead code from send/receive

[Eric Sandeen <sandeen@xxxxxxxxxx>]

cmds-recieve.c & cmds-send.c seem to have weird wrappers and
indirections, and "groups" of commands which have only
one member, which are never referenced in the code.

I think these can be removed.

Stefan, I'd appreciate your review & testing of this though!
TBH it's an old patch I had laying around, but I have
not re-tested it recently.

Thanks,
