efm2 hal handling API - full changes.

efm2 hal handling API - full changes.

1. Added E_FM_OP_EJECT command to e_fm_main. It unmounts volume
   before eject, if it necessary.
2. Added timeouts of mounting/unmounting/ejecting media, and
   it's moved to slave e_fm_main.c. Each timeout will generate
   *_MOUNT_ERROR, *_UNMOUNT_ERROR and *_EJECT_ERROR message.
3. Added auto mount on insert media and auto showing efm2 window
   on mount volume options to filemanager config.
4. Added mounted/unmounted glyphs to efm2 icons and track state
   code. Now each removable device have "M" glyph on icon if mounted
   and "U" when unmounted.
5. Added mount/unmount/eject commands to icon dropdown menu.
6. Russian translation of mew messages.
7. Other bugfixes and improvements for co-operation.

Now, efm2 contains all code to mount/umnount/eject removable media and
all code to provide corresponding user interface.
It can working independently from 'places' or co-operate with it.
