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.

Add support for default mssfix, which is calculated
based on upper bound value 1492 minus payload and
encapculation overhead.
Payload overhead includes:
- compression byte (except for V2, which doesn't add overhead)
- pktid (in CBC)
- IPv4 and TCP headers
Encapculation overhead:
- crypto overhead (for AEAD 16 bytes auth tag, 4 bytes pktid, 4 bytes opcode/peer-id = 24)
- 2 bytes packet size for TCP transport
Also for CBC we must take padding [1..blocksize] into account.

Some customers have configs with "mssfix 0",
which is invalid in openvpn3 and make it fail.
To not to break cuetomers' configs, ignore invalid
mssfix values.
Fixes OVPN3-616.
