problem found by robert@ ok jamsek, op

The commands 'got rebase -a' and 'got histedit -a' were checking out files from the wrong commit. Make them check files out from the commit we are switching the work tree to, as intended. Avoids spurious merge conflicts when the work tree is later used for another rebase operation. It also makes 'got update' right after 'rebase -a' a no-op, as it should be. Problem found by naddy@ while rebasing jca's llvm15 branch ok op, jamsek earlier version

This avoids having to run 'got update' after operations which run checkout_files() and where a file happens to have the same blob ID but its base commit differs from the commit we are updating to. Found while investigating a bug report by naddy@ ok op, jamsek (earlier version)

Add framework for scripting tog tests by capturing screen dumps to compare with expected output. Includes some preliminary log view tests but lots more tests are needed to cover diff, blame, tree, ref, and help views. ok stsp@

This should result in more useful behaviour when gitwrapper runs and repositories listed in gotd.conf do not yet exist or do no longer exist.

Spotted while looking for leaks using Otto' malloc() new leaks detection. Harmless in practice since we just forgot to call got_repo_close() when terminating in some cmd_*() functions, but still a leak. ok stsp@

Very unlikely (an occurrence of it would mean that got produced an invalid fileindex) and harmless anyway since we would just terminate, but a leak is still a leak. ok stsp@

add a regress for this case.

In diff and blame views, if the user scrolls up during a search, resume search from the first displayed line--not the current match. This makes sense in these views as the "cursor" or current line is the first line. Patch by Mikhail. ok op@

shuffle some code to handle all the page types in the switch. ok tracey@

gotd still requires the config file, of course, but gitwrapper must treat is as optional and remain silent if the file cannot be found.

Since we're going to unconditionally execute gotsh or git-*-pack, don't bother fork()ing and having the main process to wait(2), just execle()! ok stsp@
