f3c777d5ea main: Add '-devrandom' commandline option
Allows to use /dev/random for generating the master key instead of the
default Go implementation. When the kernel random generator has been
properly initialized both are considered equally secure, however:

* Versions of Go prior to 1.9 just fall back to /dev/urandom if the
  getrandom() syscall would be blocking (Go Bug #19274)

* Kernel versions prior to 3.17 do not support getrandom(), and there
  is no check if the random generator has been properly initialized
  before reading from /dev/urandom

This is especially useful for embedded hardware with low-entroy. Please
note that generation of the master key might block indefinitely if the
kernel cannot harvest enough entropy.

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 .

decda6d255 configfile: switch on Raw64 by default
As we have dropped Go 1.4 compatibility already, and will add
a new feature flag for gocryptfs v1.3 anyway, this is a good
time to enable Raw64 as well.

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.

17df345103 main: init: handle spaces in mount suggestion message
Before:
	You can now mount it using: gocryptfs a x MOUNTPOINT

After:
	You can now mount it using: gocryptfs "a x" MOUNTPOINT

This is still not bulletproof but should handle the common
case of having a space in the directory name. After all,
it's only a suggestion.

e9bb8b800c reverse: switch from GCM-SIV to AES-SIV
GCM-SIV is not yet finalized, and the reference implemenation is
painfully slow at about 2 MB/s. Switch to AES-SIV.
