boerwastaken d265c34149 btrbk: make SSH minimally chatty (always add '-q' option)
Fixes digint/btrbk#179: When SSH is chatty (informing of host key
rollover etc) the remote command output parser borks.

Axel Burri 88aa8c1fea btrbk: remove "duration" column from transaction_log/transaction_syslog
The "duration" column in the transaction log has proven to be
confusing to some users, especially on errors (e.g. "send-receive
ERROR 27" in issue #177). As it's not really necessary (duration can
be computed from the corresponding "starting" log entry), it's now
being dropped.

Axel Burri 6cf5d59644 btrbk: add support for btrfs-progs 4.12: do not fail or set realpath_cache for relative paths in btrfs_subvolume_show()
As of btrfs-progs-v4.12, the "btrfs subvolume show" command does not
print the full (absolute, resolved) path anymore [1]. Instead, it prints
the relative path to btrfs root (or "/" if it is the root).

The impact for btrbk is that we cannot fill our realpath_cache in
btrfs_subvolume_show() anymore. This is not fatal, but has the
following consequences:

  - The "check for duplicate snapshot locations" may now miss
    subvolumes specified by symlinks.

  - If multiple "volume" sections point to the same subvolume (e.g. if
    specified using symlinks) an additional "btrfs subvolume list" is
    called. Note that the subvolume will still be recognized as
    identical, and the btr_tree will not be rebuilt.

Ian Kelling d02f67a924 btrbk: get_receive_targets: also match "src.received_uuid == target.uuid"
This gets important when using an old backup disk as source.

In terms of btrfs send/receive, all subvolumes matching "uuid /
received_uuid" are valid backups.

Axel Burri 79637de5aa btrbk: raw_target_encrypt: always set "gpg --no-random-seed-file": prevents creation of "~/.gnupg/random_seed" with slight perfomance penalty.
We set "--no-random-seed-file" because one of the btrbk
design principles is to not create any files unasked. Enabling
"--no-random-seed-file" creates ~/.gnupg/random_seed, and as
such depends on $HOME to be set correctly (think on running in
cron). From gpg2(1) man page:
  --no-random-seed-file GnuPG uses a file to store its
  internal random pool over invocations This makes random
  generation faster; however sometimes write operations are not
  desired. This option can be used to achieve that with the cost
  of slower random generation.

Axel Burri 961f96833a btrbk: use "dd" for raw target output, with configurable block size (raw_target_block_size)
We use "dd" instead of shell redirections, as it is common to have
special filesystems (like NFS, SMB, FUSE) mounted on the raw target
path. By using "dd" we make sure to write in reasonably large blocks
(default=128K), which is not always the case when using redirections
(e.g. "gpg > outfile" writes in 8K blocks).

Another approach would be to always pipe through "cat", which uses
st_blksize from fstat(2) (with a minimum of 128K) to determine the
block size.

Axel Burri 3dabb507e6 btrbk: do not set "--compress-algo none" on gpg command if raw_target_compress=no

Tobias Grosser 84a5c56a83 btrbk: disable compression in gpg
We already perform compression before gpg, such that compressing in gpg
is just a waste of time. Interestingly, it seems gpg is not trying to
recompress gzip[ed] input streams, as for the default gzip compression
this patch does not change performance. However, it is necessary for
the upcoming lz4 compression to show its real benefit.

Hans van Kranenburg 59d96420c8 btrbk: add transaction logging to syslog
Add configuration option transaction_syslog, which can be set to a short
name of a syslog facility, like user or local5. Most of the ones besides
localX do not really make sense, but whatever, let the user decide.

The only logging that is relevant for logging to syslog is the logging
generated inside sub action, so it's easy to hijack all messages in
there and also send them to syslog if needed.

All output is done via print_formatted, which expects a file handle.
So, abuse a file handle to a string to be able to change as less code as
needed for this feature.

Since syslog already adds the timestamps for us, I added a syslog
formatting pattern, which is very similar to tlog, omitting the
timestap.
