multiple addresses will be treated as if each address was an
individual remote directive.
Fixed issue where UDP transport driver was calling socket
connect method synchronously. This can cause exceptions
to be thrown in corner cases, such as "No route to host"
on OSX/iOS for connections to IPv6 addresses when no default
IPv6 route exists on system. Refactoring UDP connect
operation to be asychronous fixes the issue.
Implemented remote-random.
* Fixed core segfault that would occur if external_pki_cert_request
returned an error status.
* More robust handling of External PKI alias invalidation.
* Minor fixes to allow jellybean_hack.cpp to build in
debug mode.
