fb772da697 main: forkChild: try to read /proc/self/exe
On Linux, where /proc exists, this makes sure that we are
executing ourselves again, and not some other copy of the
gocryptfs executable.

This usually does not matter, but mount(1) unsets $PATH
and sets argv[0] to just "gocryptfs".

53d6a9999d main: accept -dev, -nodev, -suid, -nosuid, -exec, -noexec
When mounted via /etc/fstab like this,

  /a /b fuse.gocryptfs default 0 0

we always get extra options passed. As reported by @mahkoh
at https://github.com/rfjakob/gocryptfs/pull/233 :

  mount passes `-o noexec` if `-o user` is set and `-o exec` is not set.
  If both `-o user` and `-o exec` are set, it passes `-o exec`.

Make these options work, and in addtion, also make -suid and -rw
work the same way.

12832851c6 daemonize: try /bin/logger if /usr/bin/logger fails
SUSE has /bin/logger, everybody else has /usr/bin/logger,
so try both.

2783eadc8f main: call logger with full path
If $PATH contains the mountpoint, searching through it
will lock us up. Use an absolute path to avoid looking
at $PATH.

496968e06c main: redirectStdFds: keep logger from holding stdout open
We passed our stdout and stderr to the new logger instance,
which makes sense to see any error message, but also means that
the fd is kept open even when we close it.

Fixes the new TestMountBackground test and
https://github.com/rfjakob/gocryptfs/issues/130 .

0b6e3ce635 main: move redirectStdFds() to daemonize.go
This really is a part of daemonization.

No code changes.

d5adde1eeb exitcodes: pull all exit code definitions into the package
This commit defines all exit codes in one place in the exitcodes
package.

Also, it adds a test to verify the exit code on incorrect
password, which is what SiriKali cares about the most.

Fixes https://github.com/rfjakob/gocryptfs/issues/77 .

7fc93ec093 main: fix USR1 race condition, fixes test flakiness
We could have gotten the signal before the handler was ready,
which caused the process to wait indefinitely. This was the reason
test.bash sometimes hung.

b527e205e2 main: rename "-f" to "-fg"
"-f" looks too much like "--force". The old variant is still
accepted for compatability.

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:

   find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +

0c80cca674 toggledlog: convert remaing naked fmt.Print*
Several fatal errors were just printed to stdout, which
meant they were invisible when running the test suite.

Fix this by introducing toggledlog.Fatal and convert as
follows:

Fatal errors     -> toggledlog.Fatal
Warnings         -> toggledlog.Warn
Password prompts -> fmt.Fprintf

d163169655 Wrap Logger to make disabling output more efficient
Instead of using SetOutput(ioutil.Discard), which means
that Printf is still called for every debug message,
use a simple and fast boolean check.

Streaming write performance improves from 86 to 93 MB/s.
