posix: use local reference to unlink

We have a local reference to os.unlink in module scope, but we still used
os.unlink inside functions. This changes util to use the local reference,
which will pave the way for combining duplicated code in future patches.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
