Pull cache directory inference logic out of lib.commandline.
This introduces lib.path_util and moves cache directory related logic,
as well as checkout inference logic, out of lib.commandline and into
this new module. This is desirable because we want cache inference to be
available independently of commandline (finer-grained dependencies).
