03c8b13371 main: ignore options rw, nosuid, nodev. 
When called from mount, we always get either "suid" or "nosuid".
As "nosuid" is the default, just ignore the options. Same for
the other options.

9cf3ced0ce main: also accept options at the end via "-o" 
For compatability with mount(1), options are also accepted as
"-o COMMA-SEPARATED-OPTIONS" at the end of the command line.
For example, "-o q,zerokey" is equivalent to "-q -zerokey".

25a8802403 main: rename "-o" option to "-ko" 
This prevents confusion with the "-o" options that is passed
by mount(1) at the end of the command line.

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.

495479dc66 main: friendlier error message on wrong number of arguments 
Before:
	Usage: gocryptfs [OPTIONS] CIPHERDIR MOUNTPOINT

After:
	Wrong number of arguments (have 9, want 2). You passed: "-nosyslog" "." "asd" "-q" "ß" "asdf" "fg" "gh" "sdf" "asd fs\\dfg"
	Usage: gocryptfs [OPTIONS] CIPHERDIR MOUNTPOINT

a985096b50 contrib: pam_mount: check if something is already mounted on DST 
pam_mount is supposed to check that as well, but it seems to get confused
by the "command#path" syntax used for FUSE. Let's do it here.

04cdc695f0 main: error out when the mount shadows the cipherdir 
For example, we cannot mount "/home/user/.cipher" at "/home/user"
because the mount will hide ".cipher" also for us.

95db38912b tests: fallocate: skip some disk usage checks on btrfs

btrfs gives different results, but that's not an error.

Also, simplify test_helpers.Du and several code paths.

Fixes #43.

db72a4489d fusefrontend_reverse cast Stat_t.Dev to uint64 (#44)

bb52937834 cryptocore: derive 512-bit key for AES-SIV

encryption, so we need a 64-byte key for AES-256. Derive
it from the master key by hashing it with SHA-512.
