adf7d75d31 main: changePassword: zero masterkey
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.

2aea2d3d62 exitcodes: add code 22 for "password is empty"
Empty passwords are not allowed. Let's give the error
it's own exit code.

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 .

6e029a3799 readpassword: increase max password size to 2048
This is the value EncFS uses, so let's follow suit.

2824218a25 readpassword: increase max password length to 2000
1000 was too low as at least one user had a password
that was longer.

3784901fce readpassword: limit password length to 1000 bytes
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.

8adfbf2dc3 Check for trailing garbage after the password
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.

extpass_test and example_filesystems_test did it wrong,

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.
