1ed08c7384 tlog: disable color codes when switching to syslog 
When gocryptfs was started on a terminal and later
daemonized, the color codes stayed active in the syslog
output.

The codes are not visible in "journalctl -f", which is why
I have not noticed it yet, but they do show up in normal
syslog as the usual "#033[33m" crap.

2d01d5f2d4 tlog: always trim trailing newlines 
The messages we print through tlog sometimes do, sometimes do
not contain a trailing newline. The stdlib logger usually drops
trailing newlines automatically, but tlog postfixes ColorReset to
the caller's message, so the logger logic does not work when we
print colored output.

Drop the newlines on our own, and add a test.

Fixes the blank lines in fsck output:

6d64dfe8f7 Only print masterkey once on -init 
It is no longer printed at all when mounting a filesystem,
printing on -init can be disabled with -q.

b6c8960b01 fsck: clean up log output 
Make sure we get only 1 warning output per
problem.

Also, add new corruption types to broken_fs_v1.4.

b96e3ee271 tlog: stop embedding log.Logger to prevent mistakes 
A few places have called tlog.Warn.Print, which directly
calls into log.Logger due to embedding, losing all features
of tlog.

Stop embedding log.Logger to make sure the internal functions
cannot be called accidentially and fix (several!) instances
that did.

547ddf4264 tlog: switch default logger to syslog 
...unless "-nosyslog" is passed.

All gocryptfs messages already go to syslog, but the messages
that the go-fuse lib emits were still printed to stdout.

Fixes issue #13 ( https://github.com/rfjakob/gocryptfs/issues/13 )

6c3f97399a Rename internal "toggledlog" package to "tlog" 
tlog is used heavily everywhere and deserves a shorter name.

Renamed using sed magic, without any manual rework:
