move odb_* declarations out of git-compat-util.h

These functions were originally conceived as wrapper functions similar to xmkstemp(). They were later moved by 463db9b10 (wrapper: move odb_* to environment.c, 2010-11-06). The more appropriate place for a declaration is in cache.h. While we're at it, let's add some basic docstrings.
