patch: handle git patches that remove symlinks (issue1438)

context: enforce memctx.files() unicity localrepo.commitctx() expects changed files lists to contain unique items and does not sort itself. Passing duplicates makes them evaluated more than once and changes the committed changelog id.

store: encode trailing period and space on directory names (issue1417) Windows won't create directories with names ending in period or space, so we encode the last period/space character in directory names of non-hashed paths in the store using reversible ~xx encoding (' ' -> '~20', '.' -> '~2e'). With this change it is possible to remove a directory ending in period or space that was inadvertantly checked in on a linux system while still being able to clone such a repository with its full history to Windows (see also issue793).

store: don't create dirs ending in period or space for hashed paths (issue1417) Windows won't create directories with names ending in period or space, so we replace the last period/space character in truncated directory names of hashed paths with some other character (underbar).

convert-cvs: correctly handle Removed replies, fixes bug 1427

Fix test-acl failure on AIX due to read only LOGNAME. On AIX /etc/profile sets LOGNAME read only. This causes test-acl to fail when it comes to set LOGNAME in do_push(). Work around this by using env to set LOGNAME and run the command.
