verification:

- when multiple common names are used (as in the curl tests), the last name
needs to be selected.

- allow comparing with encoded values, at least with BMP and ISO latin1
encoded T61strings.

if the connection is killed it blanks the pointer it points to, to make it
easier to detect usage problems whereever Curl_done() is used.

This is necessary in case the client never connects or somehow fails to do
it timely. The timeout used now is only 2 seconds, which might cause problems
on really slow hosts but longer times are painful when doing torture testing
on FTP test cases.

I'm not sure how this 'alarm' functionality works on Windows or other systems
that don't actually have the alarm() function.
