This adds support for NetBSD, using the following external dependencies: libuuid ncursesw There is no CI (yet) as enabling that on Cirrus-CI requires some work, so for now, these builds will be run manually before releases. The test suite will also need tweaking to be fully supported but the key tests are supported for now.

Enable CI builds for MaxcOS on CirrusCI.

This adds support for MacOS (Monteray onward, although should work on older MacOSes). The BSD wrapper for poll/ppoll has been lifted from the work the folks over at OpenSSH have done -- thanks!

Move the detection of UUID header files to be included portably. This will have no functional effect until MacOS detection is put in place.

Update got-{fetch,index,send}'s Makefile.am to include ratelimit.c for progress output.

endian.h is portably included on non-OpenBSD systems, so let that mechanism determine if it should be included or not.

imsg_clear frees and closes resources allocated as part of enqueueing imsgs so it's a no-op after reads. discussed with and ok stsp@

As done elsewhere, d->namlen is not a portable field from readdir, therefore simualte this via the strlen of the directory name instead.

tested by thomas, naddy, and myself

Replace FMT_SCALED_STRSIZE with (FMT_SCALED_STRSIZE - 2) as field width when formatting output for printing. FMT_SCALED_STRSIZE includes space for a nul byte and a minus sign. Output values are expected to be always positive here. ok stsp

Add missing include for the deltify test now that it depends on murmurhash2.
