6ac9dcaae0 tests: use fuse-unmount.bash 
...instead of having separate compatability logic.

ce2e610428 OSX compat: replace fusermount calls with fuse-unmount.bash 
Mac OS X does not have fusermount and uses umount instead.
The fuse-unmount.bash calls the appropriate command.

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.

Suggested by @mhogomchungu in https://github.com/rfjakob/gocryptfs/issues/77 .

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.

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.
