trac-admin should use the actual encoding of stdin/stdout when printing.

Closes #7303.

`copytree` works by recursively scanning a filesystem subtree and copy each filename one by one. The problem is that we can't assume any encoding for those filenames, so we better have to respect the byte sequence as given by `os.listdir()` (we can't expect `os.listdir()` to provide us with an unicode output on all platforms).

We also need to make sure that the parameters given to `copytree` (`src`, `dst` and the files in `skip`) are later used as `str` objects, in a reasonable encoding.

Closes #6677.

So far, only the interactive mode of trac-admin correctly handled non-ascii input.
When parameteres are given to `trac-admin` on the command line, it is not correct to use `sys.stdin.encoding`, as `sys.argv` strings are encoded using the locale encoding (`local.getpreferredencoding()`).

Related to #6677.

More precise permissions (rw) set on created files. Related to #6604.

Patch by Remy Blank.

TracStandalone: umask value is now set to a sensible `022` default.

This can also be configured using the `--umask` option for `tracd`.

Closes #6604.

Improved display of attachment search matches.

Contributed by Remy Blank, finalizes #2561.

Show an explicit "empty file" message when the previewed file is empty.

Also, the Pygments renderer transformed that empty file into a one byte '\n' file.

Closes #7281.
