vm_map: Avoid linking gaps for vm_copy_t
This does not make sense, and produces incorrect results (since
vme_end is 0, etc.)
* vm/vm_map.h (_vm_map_clip_start, _vm_map_clip_end): Add link_gap
parameter.
* vm/vm_map.c (_vm_map_entry_link): Add link_gap parameter, do not call
vm_map_gap_insert if it is 0.
(vm_map_entry_link): Set link_gap to 1 in _vm_map_entry_link call.
(_vm_map_clip_start): Add link_gap parameter, pass it to
_vm_map_entry_link call..
(vm_map_clip_start): Set link_gap_to 1 in _vm_map_clip_start call.
(vm_map_copy_entry_link): Set link_gap to 0 in _vm_map_entry_link call.
(vm_map_copy_clip_start): Set link_gap_to 0 in _vm_map_clip_start call.
(_vm_map_entry_unlink): Add unlink_gap parameter, do not call
vm_map_gap_remove if it is 0.
(vm_map_entry_unlink): Set unlink_gap to 1 in _vm_map_entry_unlink call.
(_vm_map_clip_end): Add link_gap parameter, pass it to
_vm_map_entry_link call..
(vm_map_clip_end): Set link_gap_to 1 in _vm_map_clip_end call.
(vm_map_copy_entry_unlink): Set unlink_gap to 0 in _vm_map_entry_unlink call.
(vm_map_copy_clip_end): Set link_gap_to 0 in _vm_map_clip_end call.
* vm/vm_kern.c (projected_buffer_deallocate): set link_gap to 1 in
_vm_map_clip_start and _vm_map_clip_end calls.
