* fix MSVC compiler shared library issues - mostly around 'extern const'
* add vcpkg install getopt to appveyor-windows.yml
show appveyor where to get getopt from vcpkg (non-static lib to avoid LGPL violation)
* add missing else case in lsquic_shared_support.h for windows static lib path
* have cmake spit out it's version
have cmake copy dependent dlls to build dir for tests on windows (getopt.dll)
* copy getopt.dll dep for tests
added commented version that requires >= 3.21 but handles any dll deps
* try caching boringssl dir to reduce CI build time since it's always same commit specified in config file
define VCPKG_ROOT in env since I can't seem to find it by VCPKG_ROOT or VCPKG_INSTALLED_DIR in appveyor's cmake v3.16 + vcpkg
* make windows cache dependent on yml and cmd
* sync up with changes to ls-qpack
- [API] New knob to set outgoing packet batch size.
- Aborted connection now become tickable immediately.
- Abort connection when HTTP/3 frame cannot be opened (can only happen
when malloc fails).
- [BUGFIX] Initial packet size check for IETF mini conn applies to
UDP payload, not QUIC packet.
- Support old and new school loss_bits transport parameter.
- Use Q run length of 64 as suggested in the loss bits Draft.
- Undo square wave count when packet is delayed.
- Code cleanup; minor fixes.
Add ability to create custom header set objects via callbacks.
This avoids reading and re-parsing headers from the stream.
See test/http_client.c for example implementation. (Use -B flag
to turn it on).
