	Cowlib now uses GitHub Actions for CI. As a result of this change, Cowlib is tested against OTP-24+. This commit adds initial implementations of cow_http3, cow_http3_machine and cow_qpack. Because QPACK is similar to HPACK, some encoding and decoding functions were moved to a common include file, particularly the huffman functions. The cow_http module now contains the types and functions common to all or most versions of HTTP. The types and functions specific to HTTP/1 were moved to the new cow_http1 module. Because HTTP/3 is similar to HTTP/2, part of the code processing headers is common and can be found in cow_http. Other functions common to both versions were moved out of cow_http2_machine. This commit updates comments indicating that the HTTP/2 PRIORITY mechanism will no longer be implemented.
2023-01-16	Cowlib 2.12.0	Loïc Hoguin

2020-10-07	Minor optimization in cow_hpack:update_table_size/2	Viktor Söderqvist
	Table only needs to be resized if the current size exceeds the new max size, regardless of current max size.
2020-10-07	Make HPACK encode respect new configured max size	Viktor Söderqvist
	Correction to cow_hpack:encode/2,3 according to RFC 7541, 4.3. Entry Eviction When Dynamic Table Size Changes. This change also corrects the handling of inserting entries larger than the max size, which shall result in an empty table, according to 4.4. in the same RFC. Fixes #101, #103.
2020-03-30	Fix some HPACK Huffman decoding failure cases	Loïc Hoguin
	When EOS is found within the string the decoding must fail. When the final padding is > 7 bit in length the decoding must fail as well.
2019-12-29	HPACK: Fix inline integer decodings	Loïc Hoguin
	There's no shift to be done for the first value.
2019-12-27	HPACK: Turn off Dialyzer warning about improper lists	Loïc Hoguin

2019-12-27	HPACK decode: decode integers directly to avoid copying binaries	Loïc Hoguin

2019-12-27	HPACK decode: don't try to drop entries when increasing size	Loïc Hoguin

2019-12-27	HPACK encoding now produces a more compact result	Loïc Hoguin
	This in turn leads to a small performance improvement.
2019-12-26	Fix Proper tests following cow_hpack changes	Loïc Hoguin

2019-12-26	HPACK encode shouldn't maps:get(huffman...) for every string	Loïc Hoguin

2019-12-26	Use binary append instead of lists:reverse	Loïc Hoguin

2019-12-26	Remove unused cow_hpack:decode/3 Opts argument	Loïc Hoguin

2019-12-26	HPACK encode: conditionally call an iolist_to_binary	Loïc Hoguin
	This provides a small but noticeable improvement so it's probably worth doing.
2019-12-25	Fix typo in comment	Loïc Hoguin

2019-12-25	Optimize HPACK Huffman decoding	Loïc Hoguin
	The previous naive implementation ended up not benefitting from binary match context reuse because it was matching on bit boundaries (and not bytes). This new implementation matches a byte at a time. The result is almost twice faster when decoding the examples from the HPACK RFC (before/after): cow_hpack:decode_huffman in 0.250666s cow_hpack:decode_huffman in 0.133743s
2018-04-25	Prevent the HPACK configured_max_size from being dropped	Loïc Hoguin

2018-04-23	Add proper support for table size updates	Loïc Hoguin

2017-07-10	Switch from Triq to Proper	Loïc Hoguin

2016-10-09	Fix HPACK table size tracking when table is pruned	Pablo Polvorin
	The new entry size wasn't being added to the table size after a prune. Also fixes incorrect test cases. The size number was different than the one found in RFC 7541 Appendix C.
2016-10-04	Fix Dialyzer warnings	Loïc Hoguin

2016-06-08	Fix #39: Prefer crypto:strong_rand_bytes/1	Leo Liu
	See also https://github.com/erlang/otp/pull/883
2016-05-24	HPACK: Fix an issue with header values as iolists	Loïc Hoguin

2015-03-19	Add HPACK decoding and encoding functions	Loïc Hoguin
	No decoding options have been added in this commit. They will be added in the future. Only one encoding option has been added: #{huffman => boolean()}. It allows to disable Huffman compression of strings. This compression is enabled by default.
