largefiles: file storage should be relative to repo, not relative to cwd

posix: add extended support for OS X path folding
OS X does the following transformation on paths for comparisons:
a) 8-bit strings are decoded as UTF-8 to UTF-16
b) undecodable bytes are percent-escaped
c) accented characters are converted to NFD decomposed form, approximately
d) characters are converted to _lowercase_ using internal tables
Both (c) and (d) are done using internal tables that vary from release
to release and match Unicode specs to greater or lesser extent. We
approximate these functions using Python's internal Unicode data.
With this change, Mercurial will (in almost all cases) match OS X
folding and not report unknown file aliases for files in UTF-8 or
other encodings.
largefiles: fix 'hg clone . ../foo' OSError abort
Operating on a non-existant file can cause both IOError and OSError,
depending on the function used: open raises IOError, os.lstat raises
OSError.
The largefiles code called dirstate.normal, which in turn calls
os.lstat, so OSError is the right exception to catch here.
tests: test-patchbomb.t cleanup
Let commit messages and file names describe the facts without making incorrect
guess of the actual handling of it.
tests: show actual output in test-patchbomb.t
Drop fixheader and decode base64 encoded content and show non-ascii content.
tests: test findexe() access check fixed in
