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.
Overwrite the masterkey with zeros once we
have encrypted it, and let it run out of scope.
Also get rid of the password duplicate in
readpassword.Twice.
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 .
This used to hang at 100% CPU:
cat /dev/zero | gocryptfs -init a
...and would ultimately send the box into out-of-memory.
The number 1000 is chosen arbitrarily and seems big enough
given that the password must be one line.

From the comment:
// CheckTrailingGarbage tries to read one byte from stdin and exits with a
// fatal error if the read returns any data.
// This is meant to be called after reading the password, when there is no more
// data expected. This helps to catch problems with third-party tools that
// interface with gocryptfs.
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' {} +
