Win32 apr-util's crypto, cprypto_nss and crypto_openssl now works

[Mladen Turk]

Hi,

Fixed the 1.4.x branch win32 crypto API and modules
(Mostly by adding missing build files and one API bug)
They can now compile using Mozilla's xulrunner SDK and any OpenSSSL SDK.

We could reconsider re-tagging 1.4.0 (or just making 1.4.1)
