Summary:
Check for GSO support once before the first write, cache the value and use it throughout the conn lifetime.
If GSO is not supported, ensure we use chained memory write path.

On *nix 64-bit systems a `long` is 64 bits while on Windows/MSVC it's 32-bits. Better just use the 64-bit value for consistency.

Summary:
as title. Instead of checking against the packet size limit, this
leaves a 10 bytes room since we have a bug that writes out packets that's
slightly larger than udpSendPacketLen. Most of such packet will be 1-2 bytes
larger than original packets.

Summary:
Add support for variable number of addrs so we can send data to multiple destinations.
(Note: this ignores all push blocking failures!)

Summary:
In the client transport case, an exception is thrown before return. In
the batch write maker case, the previous switch/case handles all possible cases
