This isn't defined on all systems.

This is needed for gotwebd.

This is not yet "clean", but does compile. A few things to consider: * See comments beginning with "TA:"

Bump the version in git now to the next version. Over time, this should really use the SHA1 to indicate a non-released build.

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.

Update CHANGELOG and configure.ac for the 0.68.1 release

Update CHANGELOG and configure.ac for the -portable 0.68 release.

Allow the libexec helper, `got-read-patch` to be compiled, portably.

This adds support for DragonFlyBSD.

Rather than making certain checks for panelw dependant on the underlying operating system, actually use pkg-config's detection mechanism properly. This makes the checking for panelw much easier and broader for other OSes which might have either panelw or gnupanelw.

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.
