[PATCH 00 of 11] a lot of patches concerning casefolding filesystems

[Simon Heimberg]

Several fixes are applied. The code is at
http://bitbucket.org/simohe/hg-folding or at
http://bitbucket.org/simohe/hg-folding-mq

Shall I send it to the list again?

Changes since the last version:
fix util.temprename
util.fspath is quicker on '', '.', 
files deleted since os.lstat do not raise an error
quicker version for foldedpath for mac os x
realpath returns path relative to root (on mac os x and win32)
