two functions don't need to be exported

minimal change to implementation of bcrypt to not require static globals.
add some friendlier functions.
move the classic static data api into wrapper functions.
a few more changes to come...

switch to shorter ISC license. this was ok with Niels Provos.

consolidate the base64 code in one place, and remove inadequate test code

solar's testsuite revealed insufficient validation of invalid input hashes.
add a more complete check for the rounds parameter. ok deraadt

remove redundant test

sticking strlen into a char leads to wraparound at 256. fix this and
introduce a new 'b' hash minor. still generate 'a' minors for now.

pseudo-code corrections from Solar Designer <solar@openwall.com>

arc4random_buf is the easy way to fill a buffer now. ok deraadt

Zero state buffers on return. OK deraadt@

Get rid of useless #if 0 block, especially since the code is included
immediately after.

OK millert@.

Change hard coded numbers to sizeof(buf). Also change some
sizeof(buf) - 1 to sizeof(buf), since fgets takes the whole buffer size.

We live in an ANSI C world. Remove lots of gratuitous #ifdef __STDC__ cruft.

fix base64 encoding, this problem was reported by
Solar Designer <solar@false.com> some time ago.

#if __STDC__ -> #ifdef __STDC__, now all of them.

indentation cleanup
