Fix -Wformat warnings in gnu-nat.c

I've seen some -Wformat warnings when build native gdb for hurd.

../../../git/gdb/gnu-nat.c:2384:8: error: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'vm_address_t' [-Werror=format]
../../../git/gdb/gnu-nat.c:2394:8: error: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'vm_address_t' [-Werror=format]
../../../git/gdb/gnu-nat.c: In function 'steal_exc_port':
../../../git/gdb/gnu-nat.c:2898:5: error: format '%d' expects argument of type 'int', but argument 2 has type 'mach_port_t' [-Werror=format]

in usr/include/mach/port.h, we have:

typedef vm_offset_t mach_port_t;

and in usr/include/mach/machine/vm_types.h, we have:

typedef       unsigned long   vm_offset_t;

so this patch changes '%d' to '%lu' in format string for mach_port_t
variables.

Similarly, in usr/include/mach/std_types.h, we have,

typedef      vm_offset_t     vm_address_t;

this patch also changes '%x' to '%lx' in gnu_write_inferior.

Fix missing-prototypes warnings in gnu-nat.c

A recent change (commit 3398af6aa352b0611bc9d66aed72080a876e42d4)
in gnu-nat.c causes the some missing-prototypes warnings,

../../../git/gdb/gnu-nat.c:1864:1: error: no previous prototype for 'S_proc_pid2task_reply' [-Werror=missing-prototypes]
../../../git/gdb/gnu-nat.c:1866:1: error: no previous prototype for 'S_proc_task2pid_reply' [-Werror=missing-prototypes]
../../../git/gdb/gnu-nat.c:1868:1: error: no previous prototype for 'S_proc_task2proc_reply' [-Werror=missing-prototypes]

A new macro ILL_RPC was added recently, which defines some external
functions.  However, they are not declared and GCC complains about this.

This patch is to add the declarations of these external function in
macro ILL_RPC.

abfd->section_count unexpectedly changes between 218 and 248 in:

_bfd_generic_link_add_symbols increases section_count

and simple_restore_output_info later reads unallocated part of saved_offsets.

Add g10 support to rl78-tdep.c.

The g10 is an rl78 variant which has fewer registers.  Aside from the
obvious addition of a new register_name() function which omits
registers which the g10 lacks, this change also updates the
return_value() function with the conventions specified by the ABI for
finding and setting return values.

sim: ppc: drop $(LIBS) from psim dependency

When cross-compiling GDB for PPC, there's a prerequisite "-lz" for psim
that results in a build failure. With such prerequisite, GNU Make will
try to search the library from build machine's /usr/lib which is wrong.
On 64-bit Linux build machines the compilation will fail because of this.

sim: delete duplicate SIGINT handling

Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:

  sigsave = signal (SIGINT, interrupt);

However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.

	Revise signal mapping function in GDB interface for RX sim.

	sim/rx/gdb-if.c had a function named `rx_signal_to_host'.  This
	function mapped signal numbers used by the BSP to host signal
	numbers which, at one time a while back, were used by GDB
	as target signal numbers.  This change updates the signal
	numbers returned to be those names prefixed with "GDB_SIGNAL_"
	as defined in include/gdb/signals.h.

	It also changes the name of the function somewhat to better
	match what the function currently does.  I noticed that this
	function is not static - and there's no reason for it not
	to be - so I made it static too.

	* gdb-if.c (rx_signal_to_host):  Rename to
	`rx_signal_to_gdb_signal'.  Make static.  Update all callers
	to use new name.  Use signal names from include/gdb/signals.h.
