416080203b main: accept multiple -passfile options 
Each file will be read and then concatenated
for the effictive password. This can be used as a
kind of multi-factor authenticiton.

ff04b1d83a main: untangle -masterkey handling and config loading 
This was handled both in getMasterKey(). Split it apart.

7622c9f538 main: rename parseMasterKey() -> unhexMasterKey() 
Make it clear that function does NOT parse the "-masterkey"
command line argument, it just unhexes the payload.

fe06e9f456 readpassword: delete CheckTrailingGarbage 
CheckTrailingGarbage was called even when "-passfile" was
used, which is stupid, and causes false positives:

https://github.com/rfjakob/gocryptfs/issues/391
(false error "Received trailing garbage after the password"
when using -passfile in .bash_profile)

Instead of trying to improve the logic to handle that case
and make everything even more complicated, delete the function.

It is unclear if actually helps in some cases, and it definitely
harms as shown by the above bug report.

295d432175 passfile: directly read file instead of invoking cat 
Allows better error handling, gets rid of the call to an
external program, and fixes https://github.com/rfjakob/gocryptfs/issues/278 .

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.

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 .

dc2dc9f88c main: suggest "-q" to suppress master key message 
If the user has already saved the master key and is not
aware of "-q" the master key needlessly ends up in the terminal
buffer.

Closes https://github.com/rfjakob/gocryptfs/issues/76

540f125f18 main: move masterkey warnings into parseMasterKey 
This makes sure all callers of parseMasterKey warn the user.
At the moment there is only one, but another one will be added
soon for forcing a password change when only the master key is
known.

72efd3b6c3 main: suppress master key display if not running on a terminal 
Mounting through fstab or pam_mount may get the output logged
into syslog. We don't want the master key to end up in syslog.

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' {} +

09e88f31d1 toggledlog: assume command of color handling 
We want to use colored error messages also outside of main,
so let's handle it in the logging package.

The fatal logger now automatically prints red.

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
