Return a more appropriate error, rather than CURLE_OUT_OF_MEMORY when
acquiring the credentials handle fails. This is then consistent with
the code prior to commit f7e24683c4 when log-in credentials were empty.
Fixed the ability to use the current log-in credentials with DIGEST-MD5.
I had previously disabled this functionality in commit 607883f13c as I
couldn't get this to work under Windows 8, however, from testing HTTP
Digest authentication through Windows SSPI and then further testing of
this code I have found it works in Windows 7.
Some further investigation is required to see what the differences are
between Windows 7 and 8, but for now enable this functionality as the
code will return an error when AcquireCredentialsHandle() fails.
HTTP 1.1 is clearly specified to only allow three digit response codes,
and libcurl used sscanf("%3d") for that purpose. This made libcurl
support smaller numbers but not larger. It does now, but we will not
make any specific promises nor document this further since it is going
outside of what HTTP is.

Don't call CompleteAuthToken() after InitializeSecurityContext() has
returned SEC_I_CONTINUE_NEEDED as this return code only indicates the
function should be called again after receiving a response back from
the server.
This only affected the Digest and NTLM authentication code.
For consistency with other areas of the NTLM code propagate all errors
from Curl_ntlm_core_mk_nt_hash() up the call stack rather than just
CURLE_OUT_OF_MEMORY.
- Remove SSLv3 from SSL default in darwinssl, schannel, cyassl, nss,
openssl effectively making the default TLS 1.x. axTLS is not affected
since it supports only TLS, and gnutls is not affected since it already
defaults to TLS 1.x.
- Update CURLOPT_SSLVERSION doc
... for the local variable name in functions holding the return
code. Using the same name universally makes code easier to read and
follow.
Also, unify code for checking for CURLcode errors with:
if(result) or if(!result)
instead of
if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
Prefer usage of Perl modules for sha1 calculation since there
might be systems where openssl is not installed or not in path.
If openssl is used for sha1 calculation then dont rely on cut
since it is usually not available on other systems than Linux.
