This functionality is better suited for gotadmin because it is technically a server-side repository operation when we consider the 'got' tool as the client-side tool. I have plans to move 'got import' into gotadmin as well. ok op@

There is no need to clear local variables before returning from a function. ok tracey

thanks for all the help massaging this diff

This prepares for callers of got_repo_open() that cannot afford to open files in /tmp, such as gotwebd. In a follow-up change, we could ask such callers to pass in the required amount of open temporary files. One consequence is that got_repo_open() now requires the "cpath" pledge promise. Add the "cpath" promise to affected callers and remove it once the repository has been opened. ok tracey

Replace FMT_SCALED_STRSIZE with (FMT_SCALED_STRSIZE - 2) as field width when formatting output for printing. FMT_SCALED_STRSIZE includes space for a nul byte and a minus sign. Output values are expected to be always positive here. ok stsp

Move a small amount of code from worktree.c to a new file worktree_open.c, which contains everything required to open and close a work tree and inspect some of its basic parameters. This can be used by gotadmin. ok tracey
