- #45430, windows implementation of crypt is not TS
- add Blowfish (using implementation from Solar Designer <solar at openwal dot com>) and extended DES support
- Make crypt features portable:
- if no crypt_r, php's implemetation is used (all algo and TS), php can't be used with unsafe crypt anymore
- if one algo is missing, php's implemetation is used
- Windows always use php's implementation
- removed old code in windows/
