Avoids 'work tree is already locked' errors from got commands while the 'tog diff' command remains running.

fixes an unused variable that should have been dropped in previous commit too. ok stsp@

As discussed on IRC. It makes nicer diffs and the performance hit should only be noticeable with the odd large diff. It might also be a motivator in trying to speed up the patience implementation. ok stsp@

This matches the existing use of "got -r path cmd" and "git_commit path args".

Fix a regression in db82695e31945b3ce001a5fb69674c3638622368 where the fetch_all_branches configuration setting from got.conf was dropped and always defaulted to "no". Add corresponding regression test. ok stsp

Just while cvg is being developed, mask the building of this via a flag to ./configure -- this is not intended to be used by any packagers, but rather, provide a means for developers for testing. This flag will go away once cvg is considered releasable.

cvg is still under development, and not ready to be installed yet.

When trying to run "got ci" adding a large file, this changes the following error message: got: diff_atomize_file: Cannot allocate memory into: got: /dev/null vs /path/to/the/really/big/file: diff_atomize_file: Cannot allocate memory ok stsp@

This will hopefully fix issues seen on servers where gotsh exits early for no good reason.

When checking out over a pre-existing directory tree with -E, got would store the checkout timestamp in the fileindex and so not detect local edits until those files are touch(1)ed again. Instead, detect that a file already exists during checkout and don't update its {c,m}time, leaving them to zero (the epoch), so a subsequent `got status' will look at its contents. While here, change the status char for such file from ? to E, which is what the manpage actually documents. Issue reported by naddy@ ok stsp@

Fixes 'No newline at end of file' message appearing in unexpected places. Problem noticed by op@

Reduces the indirection in fcgi.c, starts to make the struct template opaque, simplifies the template usage. All with a net negative :-) reads fine to stsp@ (thanks!)
