* docs: improve API documentation for OpenStreamSync
Both `OpenStream` and `OpenStreamSync` themselves only create steam objects locally, but `OpenStreamSync` does not add document descriptions, which will cause ambiguity.
* additional description
If the packet doesn't contain an ACK (i.e. the payload is empty),
there's no point retrying to pack it later. It's extremely unlikely that
the available packet size will suddenly increase.
This is more consistent with both the RFC and the rest of the API. For
example, the option in the Config is already name EnableDatagrams, and
the property in the ConnectionState is named SupportsDatagrams.
There is no good reason to manually set the validity period for Retry
tokens. Retry tokens are only valid on a single connection during the
handshake, so it makes sense to limit their validity to the configured
handshake timeout.

* Update interface.go

* Add support for providing a custom ConnectionID generator via Config
This work makes it possible for servers or clients to control how
ConnectionIDs are generated, which in turn will force peers in the
connection to use those ConnectionIDs as destination connection IDs when sending packets.
This is useful for scenarios where we want to perform some kind
selection on the QUIC packets at the L4 level.
* add more doc
* refactor populate config to not use provided config
* add an integration test for custom connection ID generators
* fix linter warnings

This commit introduces additional platform-dependent checking when the
kernel returns an error. Previously, the session is terminated when
PingFrame sends a discovery packet larger than the limit. With this
commit, the error is checked, and if it is "datagram too large", the
error is ignored.
Additionally,
1. This commit re-enables MTU discovery on Windows unless it
is disabled explicitly by user (Undo #3276),
2. Set IP_DONTFRAGMENT and IPV6_DONTFRAG with error checking on Windows,
and
3. Set IP_MTU_DISCOVERY to PMTUDISC_DO for both IPv4 and IPv6 on Linux
so that the kernel will return "message too long".
Fixes#3273#3327
