SSL: Add an option to disable certificate revocation checks
New tool option --ssl-no-revoke. New value CURLSSLOPT_NO_REVOKE for CURLOPT_SSL_OPTIONS. Currently this option applies only to WinSSL where we have automatic certificate revocation checking by default. According to the ssl-compared chart there are other backends that have automatic checking (NSS, wolfSSL and DarwinSSL) so we could possibly accommodate them at some later point.

.SH DESCRIPTION
Pass a long with a bitmask to tell libcurl about specific SSL behaviors.
-\fICURLSSLOPT_ALLOW_BEAST\fP is the only supported bit and by setting this the
-user will tell libcurl to not attempt to use any workarounds for a security
-flaw in the SSL3 and TLS1.0 protocols. If this option isn't used or this bit
-is set to 0, the SSL layer libcurl uses may use a work-around for this flaw
-although it might cause interoperability problems with some (older) SSL
-implementations. WARNING: avoiding this work-around lessens the security, and
-by setting this option to 1 you ask for exactly that.

+\fICURLSSLOPT_NO_REVOKE\fP tells libcurl to disable certificate revocation
+checks for those SSL backends where such behavior is present. \fBCurrently this
+option is only supported for WinSSL (the native Windows SSL library), with an
+exception in the case of Windows' Untrusted Publishers blacklist which it seems
+can't be bypassed.\fP This option may have broader support to accommodate other
+SSL backends in the future.
