schannel: add support for CURLOPT_CAINFO
- Move verify_certificate functionality in schannel.c into a new file called schannel_verify.c. Additionally, some structure defintions from schannel.c have been moved to schannel.h to allow them to be used in schannel_verify.c. - Make verify_certificate functionality for Schannel available on all versions of Windows instead of just Windows CE. verify_certificate will be invoked on Windows CE or when the user specifies CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER. - In verify_certificate, create a custom certificate chain engine that exclusively trusts the certificate store backed by the CURLOPT_CAINFO file. - doc updates of --cacert/CAINFO support for schannel - Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString when available. This implements a TODO in schannel.c to improve handling of multiple SANs in a certificate. In particular, all SANs will now be searched instead of just the first name. - Update tool_operate.c to not search for the curl-ca-bundle.crt file when using Schannel to maintain backward compatibility. Previously, any curl-ca-bundle.crt file found in that search would have been ignored by Schannel. But, with CAINFO support, the file found by that search would have been used as the certificate store and could cause issues for any users that have curl-ca-bundle.crt in the search path. - Update url.c to not set the build time CURL_CA_BUNDLE if the selected SSL backend is Schannel. We allow setting CA location for schannel only when explicitly specified by the user via CURLOPT_CAINFO / --cacert. - Add new test cases 3000 and 3001. These test cases check that the first and last SAN, respectively, matches the connection hostname. New test certificates have been added for these cases. For 3000, the certificate prefix is Server-localhost-firstSAN and for 3001, the certificate prefix is Server-localhost-secondSAN. - Remove TODO 15.2 (Add support for custom server certificate validation), this commit addresses it. Closes https://github.com/curl/curl/pull/1325
