- Fix licensing issues:
* Use upstream tarball as is, i.e. don't include third-party
stuff from vcpkg submodule.
* As a consequence, websocketpp is not embedded in tarball so
add build requirement on system's websocketpp.
- Update to 2.10.8
* Allow ppltasks.h and pplxtasks.h to co-exist
* Fix incorrect const in reinterpret_cast
* Fix UWP missing header
* Adds support for OpenSSL 1.1.1
* Fix string size for error message generated by windows_category
* Add uri_builder::append_path_raw(...) to allow adding elements
to path intentionally beginning with '/' ("//" will result in
the final path value)
* cmake: add code to detect system brotli library
* Fix Brotli compress_helper early termination issue
- Update to 2.10.7
* Several race conditions in the listener were worked around; the
listeners remain experimental and are unlikely to productized
in their current form; the race conditions are structural, but
at least the client tests pass most of the time.
* Incorrect handling of connection pooling bug that caused segfaults
on Ubuntu introduced in 2.10.4 has been repaired.
* websocketpp checked in 0.5.1 version has been changed to a
submodule and updated to 0.8.1.
* Added an API to set the number of threads in the asio thread pool
* Add Transfer-Encoding compression support and extensible compression
API
* Improve utf8_to_utf16 speed for common path
* added URI resolution according to RFC3986
* Use pplx namespace consistently
* Remove _ASYNCRTIMP from ~http_listener() and implement inline
* Avoid using identifiers reserved by C++ in header guards
* blackjack sample: use vector instead of shared pointer for array
