199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

976bb0be03 * Makefile.in (init.c): Generate using the source, not munch. This
cleans up all kinds of hassles (which nm to use in munch, etc).  The
	new formatting conventions (mostly already followed) are that
	the name of the _initialize_* routines must start in column zero,
	and must not be inside #if.
	* munch: Removed.
	* Makefile.in: Remove references to munch.
	* serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c,
	alpha-tdep.c, hp300ux-nat.c, hppab-nat.c, osfsolib.c, remote-es.c,
	procfs.c, remote-udi.c, ser-go32.c, ultra3-xdep.c, sh-tdep.c,
	i960-tdep.c, hppa-tdep.c, h8500-tdep.c, dpx2-nat.c, delta68-nat.c,
	z8k-tdep.c: Make sure the above conventions are followed.  Make
	sure they are all declared as returning void.  Clean up
	miscellaneous comments and such.

sim_kill, sim_open, or sim_set_args.

ccced87a0b * findvar.c (value_from_register): H8500 specific, check to see
if we are looking at short pointer.  If so, skip crock.
	* h8500-tdep.c (h8500_frame_chain):  Mask down value from
	read_memory_integer() to avoid getting messed up by sign extension.

5d0734a7d7 provide a new interface (using read_memory_func) to call the disassemblers
which copes with errors in a plausible way

ccf1e898d7 * findvar.c (read_register, write_register): Make these capable
of reading/writing registers that are shorter than REGISTER_TYPE.
	* (value_from_register):  Install H8500 specific code to return
	proper value when register is being used as a pointer.
	* h8500-tdep.c:  Remove extra defines of NUM_REGS.
	(h8500_skip_prologue):  Use correct lengths for LINK instructions.
	(FRAME_CHAIN):  Change name to h8500_frame_chain.  Rewrite code to
	chain frames properly by combining frame pointer with T reg.
	(init_extra_frame_info):  Delete.  It's now a macro.
	(frame_args_address):  Don't add PTR_SIZE.  Stack args are already
	offset by the correct amount off of the frame pointer.
	(register_byte):  Delete.  It's now a macro.
	(register_raw_size, register_virtual_size):  Delete.  Replaced by
	common routine h8500_register_size, cuz there's no difference
	between the raw & virtual sizes on this machine.
	(register_convert_to_raw, register_convert_to_virtual):  Delete,
	cuz there's no difference between the raw & virtual forms.
	Replaced by memcpy in tm file.
	(register_virtual_type):  Rename to h8500_register_virtual_type.
	Get rid of pointer pseudo-regs, use _REGNUM with all reg names.
	(_initialize_h8500_tdep):  Get rid of crock to ensure that GDB &
	emulator have same reg offsets.  This is all handled in the
	simulator code now.
	(h8500_trapped_internalvar):  New routine to detect references to
	convenience vars acting as pointer pseudo-regs.
	(h8500_value_trapped_internalvar):  Conjure up value of pointer
	pseudo-regs.
	(h8500_set_trapped_internalvar):  Convert set value in real
	register references.
	infcmd.c (read_pc, write_pc):  Add h8500 specific code to handle
	code segment register.
	infrun.c (proceed):  Simplify.  Call write_pc instead of doing it
	by hand.
	(wait_for_inferior):  Add h8500 specific code to add stack segment
	when reading SP register.
	remote-sim.c (fetch_register):  Spacing.
	tm-h8500.h:  #define GDB_TARGET_IS_H8500 to make it easier to
	detect cruft.  Redo all register manipulation stuff.  Get rid of
	pointer pseudo-regs.  (INIT_EXTRA_FRAME_INFO):  Adds stack segment
	to frame pointer.  (IS_TRAPPED_INTERNALVAL,
	VALUE_OF_TRAPPED_INTERNALVAR, SET_TRAPPED_INTERNALVAR):  Use these
	to create internal vars for pointer pseudo-regs.
