Curl_rand() will return a dummy and repatable random value for this
case. Makes it possible to write test cases that verify output.
Also, fake timestamp with CURL_FORCETIME set.
Only when built debug enabled of course.
Curl_ssl_random() was not used anymore so it has been
removed. Curl_rand() is enough.
create_digest_md5_message: generate base64 instead of hex string
curl_sasl: also fix memory leaks in some OOM situations
Added required "debug" feature, missed in commit 1c9aaa0bac, as NTLMv2
calls Curl_rand() which can only be fixed to a specific entropy in
debug builds.
Previously it only compared credentials if the requested needle
connection wasn't using a proxy. This caused NTLM authentication
failures when using proxies as the authentication code wasn't send on
the connection where the challenge arrived.
Added test 1215 to verify: NTLM server authentication through a proxy
(This is a modified copy of test 67)
