This is the second follow-up patch release in the 8.1.x series due to regressions and bugs that are too annoying to leave lingering around.

configure: quote the assignments for run-compiler
A regression introduced in the previous release made configure fail if the
$CC shell variable was set to something else than just a single command name. This now quotes the variable correctly.
configure: without pkg-config and no custom path, use -lnghttp2
Installations without pkg-config where nghttp2 is installed in a default directory would get a link error in the build.
http2: fix EOF handling on uploads with auth negotiation
This was a regression when using HTTP/2 for doing multi-phase authentication methods with POST, like for example Digest.
http3: send EOF indicator early as possible
By better tracking the amount of upload data, curl can avoid a superfluous final zero-length DATA packet and instead send the EOF sooner.
libcurl.m4: remove trailing ‘dnl’ that causes this to break autoconf
The configure macro we ship for other projects to use to detect installed libcurl version now works better.
libssh: when keyboard-interactive auth fails, try password
When a SSH server allows multiple auth methods, and curl tried keyboard-interactive it would wrongly skip trying the password method – if built to use libssh. This bug has been present all since libssh support shipped.
