Release 2.27.1 - [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).

Latest changes - [API Change] lsquic_engine_connect() returns pointer to the connection object. - [API Change] Add lsquic_conn_get_engine() to get engine object from connection object. - [API Change] Add lsquic_conn_status() to query connection status. - [API Change] Add add lsquic_conn_set_ctx(). - [API Change] Add new timestamp format, e.g. 2017-03-21 13:43:46.671345 - [OPTIMIZATION] Process handshake STREAM frames as soon as packet arrives. - [OPTIMIZATION] Do not compile expensive send controller sanity check by default. - [OPTIMIZATION] Add fast path to gquic_be_gen_reg_pkt_header. - [OPTIMIZATION] Only make squeeze function call if necessary. - [OPTIMIZATION] Speed up Q039 ACK frame parsing. - [OPTIMIZATION] Fit most used elements of packet_out into first 64 bytes. - [OPTIMIZATION] Keep track of scheduled bytes instead of calculating. - [OPTIMIZATION] Prefetch next unacked packet when processing ACK. - [OPTIMIZATION] Leverage fact that ACK ranges and unacked list are. ordered. - [OPTIMIZATION] Reduce function pointer use for STREAM frame generation - Fix: reset incoming streams that arrive after we send GOAWAY. - Fix: delay client on_new_conn() call until connection is fully set up. - Fixes to buffered packets logic: splitting, STREAM frame elision. - Fix: do not dispatch on_write callback if no packets are available. - Fix WINDOW_UPDATE send and resend logic. - Fix STREAM frame extension code. - Fix: Drop unflushed data when stream is reset. - Switch to tracking CWND using bytes rather than packets. - Fix TCP friendly adjustment in cubic. - Fix: do not generate invalid STOP_WAITING frames during high packet loss. - Pacer fixes.

[WIP] use vcpkg for getopt; build windows shared lib enhancements (#350) * 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
