Merge of r4674, r4675, r4676: win32 fixes. *) Win32: disallowed access to various non-canonical name variants. This includes trailings dots and spaces, NTFS streams (and short names, as previously checked). The checks are now also done in ngx_file_info(), thus allowing to use the "try_files" directive to protect external scripts. *) Win32: normalization of trailing dot inside uri. Windows treats "/directory./" identical to "/directory/". Do the same when working on Windows. Note that the behaviour is different from one with last path component (where multiple spaces and dots are ignored by Windows). *) Win32: uris with ":$" are now rejected. There are too many problems with special NTFS streams, notably "::$data", "::$index_allocation" and ":$i30:$index_allocation". For now we don't reject all URIs with ":" like Apache does as there are no good reasons seen yet, and there are multiple programs using it in URLs (e.g. MediaWiki).
