Always obfuscate the author when generating `comment:` labels for reply to ticket comments. Fixes #7431.

0.12dev: merged changes from 0.11-stable [7350-7352,7356-7363]

0.12dev: merged r7346 (''In TracReports, not all user parameters from the request were propagated to the report page links (closes #7424)'')

#6677: don't support hot-copy (or any other operation) when specifying an environment path containing non-ascii characters, as the rest of Trac doesn't support using such locations anyway.

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.

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

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

Closes #6604.
