Rename BufferAllocated --> BufferAllocatedRc
Buffer: split RC from BufferAllocated
Also make changes as needed where BufferAllocated is used
Buffer: Split allocation flags into own struct
Leaving flags in template causes each alias to have identical flags
by different names, which requires each type to pointlessly use
the nested name.
Make RC: Clean up headers buffer.hpp, make_rc.hpp

The AppControl feature provides an internal communications channel that
is described in detail in the relevant commits that implement it. This
change adds two intrinsic app control 'protocols' to the list of
supported handlers in the client. The new protocols are:
- cxa1: This is a request for the client to begin a TLS handshake via
the app control channel.
- cck1: This is the protocol that allows the exchange of the requested
TLS handshake data.
The 'cxa1' handler parses the request and initiates the handshake from
the client. This handshake is exchanged via the 'cck1' protocol and
serves to prove to the server that the client has access to the required
private key.

This adds the capability to implement a custom app level protocol
that support message passing over the OpenVPN control channel.
The protocol is agnostic to the data that is transported over it
and the message splitting/reassmbly is handled transparently by the
OpenVPN library itself.
