Prototype for X509_check_host() has changed, detect this in configure.ac
ChangeLog addition:
2015-04-09 Aidan Kehoe <kehoea@parhasard.net>
* configure.ac:
If X509_check_host() is available, check the number of arguments
it takes. Don't use it if it takes any number of arguments other
than five. Also don't use it if <openssl/x509v3.h> does not
declare it, since if that is so there is no portable way to tell
how many arguments it should take, and so we would end up smashing
the stack.
* configure: Regenerate.
src/ChangeLog addition:
2015-04-09 Aidan Kehoe <kehoea@parhasard.net>
* tls.c:
#include <openssl/x509v3.h> for its prototype for
X509_check_host().
* tls.c (tls_open):
Pass the new fifth argument to X509_check_host().
