libcmis,ucb: cmis: improve AllowInsecureProtocols implementation

1. in libcmis, pass the CurlInitProtocolsFunction to all subclasses of
HttpSession that need it, and add 2 upstream fixes to pass it around

2. Arrange for InitCurl_easy to be called in UCP RepoContent as well

3. If AllowInsecureProtocols is disabled, automatically upgrade
http connections to https, as is already done in webdav-curl.
Do this in Content and RepoContent; hopefully should work
to convert when m_aURL member is initialised;
the m_xIdentifier on the other hand should have the original
URL because ContentProviderImplHelper::queryExistingContents()
caching likely relies on that.
