- [FEATURE] Add lsquic_stream_pwritev(). This function allows one to reduce the number of system calls required to read a file from disk by using lsquic_stream_pwritev() together with preadv(2). - [BUGFIX] When stream is reset, it is writeable -- let user collect the error. - [BUGFIX] Calculate correct conn flow control if reading ends early. - [BUGFIX] Remove stream from read and write queues on internal shutdown. This is a regression introduced in 2.19.7. - [BUGFIX] Swapped arguments in IETF RESET_FRAME generation. - Turn off mini conn history when compiling with Visual Studio; this allows the project to compile on Windows again. - http_client: Add -3 flag to stop reading from streams early; code cleanup. - Don't use -Werror.

- [API] Rename "0-RTT" to "session resumption." In IETF QUIC, "0-RTT" always refers to early data, meaning a request that the server can reply to in the very first return flight. A more appropriate name for what we support on the client site is "session resumption," which is standard TLS terminology. Later, when we add support for 0-RTT (early data), we can use the 0-RTT terminology again, this time in proper context. - [BUGFIX] Do not set certificate callback if ea_lookup_cert is NULL. - [BUGFIX] Make connection tickable when it's marked as closed. - [BUGFIX] Fail certificate lookup if SNI is not present in HTTP mode. - Several documentation fixes and improvements. - Minor code cleanup.
