Axel Burri 7a4a54db97 btrbk: disallow newline in files 
While most functionality works fine, raw backups fail to write correct
"FILE=" information in info sidecar.

Disallowing newlines in files is a good idea in general.

Axel Burri af86dc8c52 btrbk: allow compressors not to have a compression level 
Not all compressors support compression level (option `-#`): print a
warning if compress_level is set, and ignore its value for such
compressors.

Christoph Anton Mitterer af2d7b2c99 documentation: use "example.org" in examples 
`mydomain.com` is actually a real domain and shouln’t be used in examples.

RFC 2606 (respectively RFC 6761) reserves `example.org` (and others) for that
purpose.

Christoph Anton Mitterer 1287547df0 documentation: use "restrict" in authorized_keys for further hardening 
Since `btrbk` executes only commands, it shouldn’t need any of what’s currently
disabled with the `restrict` flag in the `authorized_keys` file, that is:
Port-, agent- and X11-forwarding as well as PTY allocation and execution of
`~/.ssh/rc`.

Axel Burri dcee6222be btrbk: append to info file instead of rewriting 
A redirection (e.g. `echo foo > bar.info`) can cause empty (zero-size)
files in some circumstances.

We still write INCOMPLETE=1 to the info file before send/receive, but
instead of re-creating it without the INCOMPLETE flag, we append
INCOMPLETE=0 (keeping up compatibility with old versions of btrbk).

Matthieu Patou 4e5ae975d8 btrbk: ignore zero-size info files 
When backuping from devices that have configured to use raw backup and
that might disconnect from the network (ie. laptops) you end up once in
a while with 0 size info file (and backup file).
btrbk don't know how to handle 0 file and stop backing up until the zero
size file is removed.
With this change 0 size info file will be ignored, and hence the backup
for the given backup will be redone.

Axel Burri cf2065df30 btrbk: hint missing ssh_identity on errors 
It is perfectly ok to run btrbk without ssh_identity (using ssh
defaults), printing a warning if the option is not set is wrong.
Instead, hackily check for ssh_identity on ssh errors, and give a hint
in the error message.
