Hi tech@

While reading htpasswd and htpasswd handling in httpd I noticed that both use
different APIs to handle encrypting/decrypting the passwords.

- htpasswd uses the bcrypt API
- httpd uses the new crypt API

The documentation for bcrypt states:
     These functions are deprecated in favor of crypt_checkpass(3) and
     crypt_newhash(3).

I'm attaching a diff moving htpasswd to the new API. Tested with httpd from
6.1 with a htpasswd generated with the diff applied on current.

Feedback? OK's?

Regards,
Adam
