Make libcrypt thread-safe. Add crypt_r(3).

glibc has a pretty nice function called crypt_r(3), which is nothing
more than crypt(3), but thread-safe. It accomplishes this by introducing
a 'struct crypt_data' structure that contains a buffer that is large
enough to hold the resulting string.

Let's go ahead and also add this function. It would be a shame if a
useful function like this wouldn't be usable in multithreaded apps.
Refactor crypt.c and all of the backends to no longer declare static
arrays, but write their output in a provided buffer.

There is no need to do any buffer length computation here, as we'll just
need to ensure that 'struct crypt_data' is large enough, which it is.
_PASSWORD_LEN is defined to 128 bytes, but in this case I'm picking 256,
as this is going to be part of the actual ABI.

Refresh our implementation of OpenBSD's Blowfish password format.

Notable changes:

- Support of $2b$ password format to address a problem where very
long passwords (more than 256 characters, when an integer
overflow would happen and cause the length to wrap at 256).
- Updated pseudo code in comments to reflect the reality.
- Removed our local shortcut of processing magic string and rely
on the centralized and tigntened validation.
- Diff reduction from upstream.

For now we are still generating the older $02a$ format of password
but we will migrate to the new format once the format is formally
finalized.
