This is needed for gotwebd.

Siphash is being used in place of murmurhash for object-id set as this is faster. However, this isn't really seen much in the non-BSD userspace, so provide an implementation for it portably, if one isn't found.

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.

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!

landlock is a new set of linux APIs that is conceptually similar to unveil(2): the idea is to restrict what a process can do on a specified part of the filesystem. There are some differences in the behaviour: the major one being that the landlock ruleset is inherited across execve(2). This just restricts the libexec helpers by completely revoking ANY filesystem access; after all they are the biggest attack surface. got send/fetch/clone *may* end up spawning ssh(1), so at the moment is not possible to landlock the main process. From Omar Polo.

Allow for warnings via AM_CFLAGS in a common Makefile, and let those values propagate to all other Makefiles. Currently the more useful checks are disabled until upstream changes are made to reduce warnings. While here, also fix the version string to remove quotes.

Fix up a weird automerge where some files referenced are either not used any more or have already been included.

This commit modifies the GoT main branch to be able to compile it under linux.

libexec is a common path which is understood by autotools, and should be honoured. Patch from Christian "naddy" Weisgerber

This adds the capability to compile got-portable on FreeBSD.

The uuid.c source file was missing a trailing backslash.

Rather than having a toplevel EXTRA_DIST target in the toplevel Makefile.am file, move the relevant files to their own Makefile.am locations.

There is only one user which calls xrecallocarray: ibuf_realloc(). We already provide recallocarray() in the compat layer so ibuf_realloc() can simply call recallocarray() directly, as it does on OpenBSD. OK thomas.adam

The got_lib_privsep.h header expects the path to the libexec directory to be called GOT_LIBEXECDIR. At the moment it always falls back to using /usr/libexec. Fix what looks to be a typo.
