new crypt implementation, latest DES version used, blowfish support

Hi,

Please find in the links ([1] and [2]) below an updated version of the
crypt rewrite and fix (#45430).

The changes are:

- Use of the latest DES implementation ported to windows (using
CriticalSection for the locking)
- Blowfish support with salt generation (could be used for non windows
build as well)
- moved all the crypt code to win32/crypt
- added COPYING info about the licenses of the various algorithms (no
new weird licenses introduced)

Please test it, I like to fix the last possible issues before a commit :)


Some tests (from the manual but the blowfish without salt):
if (CRYPT_STD_DES == 1) {
    echo 'Standard DES: ' . crypt('rasmuslerdorf', 'rl') . "\n";
}

if (CRYPT_EXT_DES == 1) {
    echo 'Extended DES: ' . crypt('rasmuslerdorf', '_J9..rasm') . "\n";
}

if (CRYPT_MD5 == 1) {
    echo 'MD5:          ' . crypt('rasmuslerdorf', '$1$rasmusle$') . "\n";
}

if (CRYPT_BLOWFISH == 1) {
    echo 'BLOWFISH:     ' . crypt('rasmuslerdorf',
'$2a$07$rasmuslerd...........$') . "\n";
    echo 'BLOWFISH:     ' . crypt('rasmuslerdorf') . "\n"; /* Test
without salt */
}
