I was shocked to discover that 'btrfs receive --dump' doesn't print a
space after long filenames, so it runs together into the metadata; for
example:
truncate ./20-00-03/this-name-is-32-characters-longsize=0
This is a trivial patch to add a single space unconditionally, so the
result is the following:
truncate ./20-00-03/this-name-is-32-characters-long size=0
I suppose this is technically a breaking change, but it seems unlikely
to me that anyone would depend on the existing behavior given how
unfriendly it is.

The send dump prints one line per stream operation, we'd like to prevent
any line breakage, so the characters are printed escaped in the C style.

Introduce send-dump.[ch] which implements a new btrfs_send_ops to
exam and output all operations inside a send stream.
It has a better output format than the old and no longer compilable
send-test tool, but still tries to be script friendly.
Provides the basis for later "inspect-internal dump-send" command.

[ drop escaping call from __print_dump for now, drop gcc warning tweaks,
replace empty format strings with NULL ]
