common: add ssl_verify.c common code

Code adapter from RedPeer::ssl_verify_callback() and used by
spice-gtk.

Since v1:
 - fixed Makefile.am
 - added config.h include
 - autoconf alloca added in patch series
 - moved int escape inside for loop
 - added a failed case when missing assignment
 - replaced strlen () by -1
 - skip spaces after comma
 - c++ guards

I didn't use bool, because openSSL uses int, and it is more future
proof for error reporting.
