The gotd parent process has lost access to client capabilities. Take the easy way out and remove related code. If needed, client capabilities can still be found in the debug log with 'gotd -v'. ok op, jamsek

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@
