OpenVPN 2.4 builds with mbedTLS 2.x, rename openvpn-polarssl
variant to openvpn-mbedtls.
Some feature highlights:
* Data channel cipher negotiation
* AEAD cipher support for data channel encryption (currently only
* AES-GCM)
* ECDH key exchange for control channel
* LZ4 compression support
See https://github.com/OpenVPN/openvpn/blob/master/Changes.rst
for additional change notes.

Upstream OpenSSL hardening work introduced a change in shared code that
causes polarssl / mbedtls builds to break when no --tls-cipher is specified.
Import the upstream fix commit as patch until the next OpenVPN release gets
released and packaged.

Only costs about 3k compressed, but significantly improves handling of
configuration mismatch

OpenVPN assumes that its control channel messages are sent and received
unfragmented, this assumption is broken when CBC record splitting is
enabled in mbedTLS.
The record splitting is intended as countermeasure against BEAST attacks
which do not apply to OpenVPN, therefore we simply disable it until
upstream OpenVPN gains the ability to process fragmented control
messages.
Disabling the splitting also works around a (not remotely triggerable)
segmentation fault in mbedTLS.
