The new session process is able to manipulate files in the repository and keeps track of the read/write client session state. The parent process now restricts its view of the filesystem to the absolute path stored in argv[0], and combines this with unveil "x" on this path. As a result the parent process can only re-exec itself. small tweaks + ok op@

otherwise most test fails because of double "/" ending in paths and tricking some check into thinking that's failed. ok jamsek stsp

Ensure an actual file path is displayed in the 'got diff -d -c commit path ...' case when one of the specified paths is a deleted file. Prior to this, the unhelpful "/dev/null" label was shown instead. Includes some copypasta fixes noted by op. ok stsp@ op@

Accept flag parameter to optionally specify which pointers to free. This saves callers looping through the list to free pointers. ok + fix stsp@

Reviewed and uncovered as part of the diff in the forthcoming commit (pathlist API refactor). ok stsp@

Like got log -d, add the switch to 'got diff' to display a diffstat of changes; as per stsp's suggestion, we always include diff output with the diffstat. Disabled in gotwebd (for now :) Includes tweaks from op@ ok stsp@

Previously the gotd tests were only running fresh clones.

There was a bug where we reused a file stored in *outfd from a previous call, resulting in a raw object backed by a file but with tempfile_idx -1. This then caused bad confusion during deltification. Fix this by passing tempfd to read_raw() functions and only setting *outfd in case it is actually required, and returning tempfd to the repository tempfile pool otherwise. ok tracey

Without this we end up being confused about whether a raw object has been mapped into memory, leading to crashes. ok op@

Also, separate g/G from home/end in the manual and runtime help text as only the former accept a prefixed count modifier. Based on initial diff from Mikhail. ok stsp@

trap on EXIT too so the lockfile is deleted on quit (both successful and not.) While here simplify a cd too. ok stsp@

This ensures that all repositories exist when the process is first started. It will also help to avoid an "rpath" pledge promise in a future gotd which uses a separate session process, by avoiding realpath() calls while starting new processes.

echo \n is not really portable. Not that it matters since the regress suite is already using non-POSIX features (like `local'). However, it's the only place using it and easy to fix. ok jamsek
