Simon Marchi 6e1e1966ba Pass inferior down to target_detach and to_detach
The to_detach target_ops method implementations are currently expected
to work on current_inferior/inferior_ptid.  In order to make things more
explicit, and remove some "shadow" parameter passing through globals,
this patch adds an "inferior" parameter to to_detach.  Implementations
will be expected to use this instead of relying on the global.  However,
to keep things simple, this patch only does the minimum that is
necessary to add the parameter.  The following patch gives an example of
how one such implementation would be adapted.  If the approach is deemed
good, we can then look into adapting more implementations.  Until then,
they'll continue to work as they do currently.

gdb/ChangeLog:

	* target.h (struct target_ops) <to_detach>: Add inferior
	parameter.
	(target_detach): Likewise.
	* target.c (dispose_inferior): Pass inferior down.
	(target_detach): Pass inferior down.  Assert that it is equal to
	the current inferior.
	* aix-thread.c (aix_thread_detach): Pass inferior down.
	* corefile.c (core_file_command): Pass current_inferior() down.
	* corelow.c (core_detach): Add inferior parameter.
	* darwin-nat.c (darwin_detach): Likewise.
	* gnu-nat.c (gnu_detach): Likewise.
	* inf-ptrace.c (inf_ptrace_detach): Likewise.
	* infcmd.c (detach_command): Pass current_inferior() down to
	target_detach.
	* infrun.c (follow_fork_inferior): Pass parent_inf to
	target_detach.
	(handle_vfork_child_exec_or_exit): Pass inf->vfork_parent to
	target_detach.
	* linux-nat.c (linux_nat_detach): Add inferior parameter.
	* linux-thread-db.c (thread_db_detach): Likewise.
	* nto-procfs.c (procfs_detach): Likewise.
	* procfs.c (procfs_detach): Likewise.
	* record.c (record_detach): Likewise.
	* record.h (struct inferior): Forward-declare.
	(record_detach): Add inferior parameter.
	* remote-sim.c (gdbsim_detach): Likewise.
	* remote.c (remote_detach_1): Likewise.
	(remote_detach): Likewise.
	(extended_remote_detach): Likewise.
	* sol-thread.c (sol_thread_detach): Likewise.
	* target-debug.h (target_debug_print_inferior_p): New macro.
	* target-delegates.c: Re-generate.
	* top.c (kill_or_detach): Pass inferior down to target_detach.
	* windows-nat.c (windows_detach): Add inferior parameter.

#ifndef TARGET_DEBUG_H

/* Printers for the debug target. Each prints an object of a given
type to a string that needn't be freed. Most printers are macros,
for brevity, but a few are static functions where more complicated
behavior is needed.
References to these printers are automatically generated by
make-target-delegates. See the generated file target-delegates.c.
In a couple cases, a special printing function is defined and then
used via the TARGET_DEBUG_PRINTER macro. See target.h.
A few methods still have some explicit targetdebug code in
target.c. In most cases this is because target delegation hasn't
been done for the method; but individual cases vary. For instance,
target_store_registers does some special register printing that is
more simply done there, and target_xfer_partial additionally
bypasses the debug target. */
