Log Message:
remove unused share map code from UVM:
- replace map checks with submap checks
- get rid of unused 'mainonly' arg in uvm_unmap/uvm_unmap_remove, simplify
code.   update all calls to reflect this.
- don't worry about unmapping or changing the protection of shared share
map mappings (is_main_map no longer used).
- remove unused uvm_map_sharemapcopy() function from fork code.
