If a short read happens, or if all the fastcgi record to read don't fit in the buffer, gotwebd fails to continue reading and hits the timeout. If this happens before gotweb_process_request is called, it will crash in gotweb_free_transport since c->t will be NULL. This register the event with EV_PERSIST so fcgi_request is called again when there's more to read and guards gotweb_free_transport. It also makes spaces for the records as soon as they're successfully parsed. With lots of help from stsp ok stsp@

Escape the path to the repository when connecting via SSH. This is needed if the path contains spaces, quotes or other "funny" characters, but also by git-shell which requires the argument to be surrounded by single-quote characters. Issue with git-shell reported by James Cook, fix based on an initial diff by stsp@. ok stsp@

`got log' is ran twice against $testroot/repo so log-repo and log-repo-clone are identical. Instead, run `got log' on the clone repo the second time. ok stsp@

The default branch in -portable has changed from linux -> portable, and so the documentation needs updating as well.

Now that the former "linux" branch is being retired, change the portable sync script to reference "portable".

Make gotsh pass all have-lines sent by clients onwards to gotd, reducing size of pack files generated by the repo_read process. Problem reported by naddy@ ok jamsek

Fixes a race condition on NFS where the file's modify time may change while the file is being edited, causing the editor to complain. OK stsp

* Move the main incldue/got_compat.h to the top of the files they're included in. * Define SHA256Init and friends to the system equivalents.

When checking for ncurses, don't clobber previous checks for libpanel.

Remove useless headers which don't need to be included any longer.

When looking for base64 functions, check -lresolv and/or -lnetwork, and only build those in compat if required. Some of the detection code was modified from tmux's configure.ac script.

Some code in compat/ has #defines which were not being checked for in configure.ac, which could have lead to compilation failures were those files to be included on systems which needed them. In doing so, we can now remove libmd and libcrypto as these are no longer needed.

Don't use a custom variable when the header checks for these are already available. From Christian "naddy" Weisgerber.

Because musl is less forgiving about header-ordering, explicitly include this before stdio.h -- this won't affect existing files as the include guards elsewhere prevent this.

When building tests, compat needs to be built. Do this prior to running any tests. This ensures tests can be run from a clean tree. Furthermore, add got_compat.h to all test headers. This wasn't necessary before as this was implicitly being included, but now isn't.

Set LIBS to the empty string so that only the specific dependencies are included where needed, rather than relying on autotools to do this for us. This will make splitting out got into different subprojects easier, as well as allow for multi-packing on those systems which support it.

Extend the include guard to the whole file.
