This check works also with to non-configure platforms.

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.

Code cleanup to try and synchronise code between the different SSPI

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.

Each shows evidence of flakiness on at least one platform on
the autobuilds. Users can use this keyword to skip these tests
if desired.

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.

Added support for WinIDN build configurations to the VC8 and VC9
project files.

If Apple ever drops SSLv3 support from the Security framework, we'll fail with an error if the user insists on using SSLv3.

- 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)
