* remote.c (remote_start_remote): If the solib list is global,

Browse source 
fetch libraries and insert breakpoints after connecting.
	* infcmd.c (post_create_inferior): If the solist is shared between
	inferiors, no need to refetch it on every new inferior.
	(detach_command): If the shared library list is shared between
	inferiors, then don't clear it on every inferior detach.
	* gdbarch.sh (has_global_solist): New.
	* i386-dicos-tdep.c (i386_dicos_init_abi): Set
	gdbarch_has_global_solist.
	* target.c (target_pre_inferior): If the shared library list is
	shared between inferiors, then don't clear it here, neither
	invalidate the memory regions or clear the target description.
	(target_detach): If the shared library list is shared between
	inferiors, then don't remove breakpoints from the target here.
	(target_disconnect): Comment.
	* solib.c (update_solib_list): Check for null_ptid.
	* breakpoint.c (insert_breakpoints, update_global_location_list):
	If the shared library list is shared between inferiors, insert
	breakpoints even if there's no execution.
	(breakpoint_init_inferior): If the shared library list is shared
	between inferiors, don't delete breakpoints or mark them
	uninserted here.

	* gdbarch.c, gdbarch.h: Regenerate.
