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

Fixes https://github.com/rfjakob/gocryptfs/issues/93

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.

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.
