configure.ac: expand the check for sys/tree.h do not just see if it's there, make sure it is usable. Currently, alpine sys/tree.h generates code that doesn't work with both gcc and clang (for different reasons!) so make sure we can actually use it, or fall back on the bundled version.

add -Wno-pointer-sign to the mix

configure: look for errc instead of err

configure.ac: kill unused variables

endian.h is not universally available FreeBSD and NetBSD have sys/endian.h, on MacOS we need to use the functions from libkern/OSByteOrder.h see github issue #1

include compat for reallocarray too reported by @Et7f3 in github issue #1, thanks!

tag 0.2 * fix twstat handling of mode bits * rejects incoming connections with a ridiculously small msize * allow "jumbo" (i.e. more than 16K) Twrite and Treads * allow Tread to read exactly msize bytes * kamiftp: fix reads wrt msize * kamiftp: do maximum reads and writes

add kamiproxy: a 9p-over-tls proxy for plaintext 9p kamiproxy is a TLS-capable proxy that forwards the traffic it gets over plaintext 9p on a local port to a remote 9p server. It uses (and mandates) tls client certificates.

transform compat/ into a static library

fix bundling of contrib/ stuff

opt-in some warnings

use serial ids and drop usage of arc4random it's not so useful here and not (directly) used anywhere else.

include test in the distribution tarball while here also delete the two remaining makefiles from before the -portable merge.

fix project name; `kamid' not -portable

fix readline on !OpenBSD I talked too fast. There's a typo that disabled readline even if found with pkg-config, and also the way I hooked it in kamiftp was wrong...
