win32mbcs: Add configuration to specify path encoding

Add win32mbcs.encoding configuration option to specify the encoding to
use instead of encoding.encoding.

This option is useful for the users who want to write UTF-8 log
message on non UTF-8 path encoding environment.

 Note that there are some limitations on using this extension:
 
 - You should use single encoding in one repository.
-- You should set same encoding for the repository by locale or
-  HGENCODING.

+By default, win32mbcs uses encoding.encoding decided by mercurial.
+You can specify the encoding by config option.
 
-Path encoding conversion are done between Unicode and
-encoding.encoding which is decided by Mercurial from current locale
-setting or HGENCODING.
