icasefs: rewrite comment to explain situtation precisely

icasefs: follow standard cache look up pattern

icasefs: disuse length check against un-normcase()-ed filenames this patch disuses length check against un-normcase()-ed filenames gotten by "os.listdir()", because there is no assurance that filesystem stores filenames normalized except in letter case, even though some case insensitive filesystems (in some environment, for some language setting) store them in such manner.

phases: do not exchange secret changesets Any secret changesets will be excluded from pull and push. Phase data are properly synchronized on pull and push if a changeset is seen as secret locally but is non-secret remote side. This patch does not handle the case of a changeset secret on remote but known locally.

phases: test the new-commit option and proper inheritence of phase

cygwin: add cygwin specific normcase logic in cygwin environment, mount point part of path is treated as case sensitive, even though underlying NTFS is case insensitive. this patch preserves mount point part of specified path, only if it is absolute one. there is no easy way to get list of current mount points from python program, other than to execute "mount" external command, because cygwin does not store current mount points into Unix/Linux like /etc/XXXtab file. so, this patch introduces cygwinmountpoints variable to list mount points to be preserved case. this allows some other extensions to customize mount point configuration.
