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

-- disambiguate new_obj(): new_man_obj(), new_tun_obj
-- remove obfuscatory typedef <class> Base; use <class>
-- in servproto.hpp typedef ProtoContext::ProtoConfig to ProtoConfig
since Arne's already disambiguated Config
-- disambiguate Link<>: TCPLink<>, UDPLink<>
Added TODO comment on unneeded version of control_net_recv()

Usually caused by the only use being in macros that do not
necessarily expand to code depending on the preprocessor
flags.
While here, convert existing work-arounds to [[maybe_unused]]
as well.

PacketStream was originally used in the OpenVPN protocol
to segment a TCP stream into packets. Then we realized
it could perform the same function for the DNS protocol.
Now there are other protocols of interest (such as the
Vici protocol in Strongswan) that also use stream
segmentation, but use a different word size for the
stream length as represented on the wire protocol.
OpenVPN and DNS use a 16 bit word size, while Vici uses
a 32 bit word size. Both use network-endian encoding
of the word size.
So this patch makes the stream length word size a
template parameter.

- Used static_cast instead of direct type conversions in places where
it's safe
- Used numeric_cast where failure is possible
- Changed types of arguments and locals when practical

This is the result after running 'clang-format -i' on all C++ files and
headers, with the defined formatting rules in .clang-format.
Only the openvpn/common/unicode-impl.hpp has been excluded, as that is
mostly a copy of an external project.

In case of error along the TCP RX path it is better to grab the error
coming with the exception and report it back up.
For this reason, catch ExceptionCode objects rather than std::exception
as the former carries the error code together with the text message.

Platforms like UWP and iOS may call core methods
from another threads. Since core is not thread-safe,
we provide OPENVPN_ASYNC_HANDLER macro which instantiates
lock guard. It follows RAII principle and locks global
mutex in constructor and unlocks in destructor. This
guarantees that code in block protected with this macro
won't be called simultaneously from different threads.

This class is an "interface" for TCP Links. It can be used by Transport
layers instead of the actual concrete Link class.

To allow other types of TCP Link to be implemented,
factor out code that can be re-used by other implementations
and move it to the LinkCommon class.
TCPTransport::Link now inherits from LinkCommon.
