vine: handling temp files when peer transfers disabled

[colinthomas-z80]

Proposed Changes

If peer transfers are disabled change temp file behavior so they are returned on creation like normal files. Taskvine will still manage naming and cleanup after the workflow completes.

I am thinking about how to add a mechanism to clean up these local temp files when the workflow completes, to make them similar in function to real temp files

This would seem to give all temp files from the same user the same name.

char *name = string_format("temp-local-%u", uid);

Am I missing something?

You are right. I was mistaken about uid vs. uuid behavior
