sim: add more hacking notes

I found the documentation lacking in many places, so I tried filling in a
lot of holes that I personally fell into.

Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Remove gdb/gdbserver/ line.

gdb/gdbserver/
* linux-low.c (linux_mourn): Also remove the process.
* server.c (handle_target_event): Don't remove the process here.
* nto-low.c (nto_mourn): New.
(nto_target_ops): Install it.
* spu-low.c (spu_mourn): New.
(spu_target_ops): Install it.
* win32-low.c (win32_mourn): New.
(win32_target_ops): Install it.

sim: add helper macros for branch profiling

The profile code has a lot of helper macros already, but none yet for the
branch profiling code.  So add ones for the basic functions -- taken and
untaken branches.

sim: add missing values to array initializers

The sim code has a lot of static initializer for options and devices, but
since they aren't using newer struct style, they have to specify a value
for every option otherwise gcc spits a lot of warnings about "missing
initializer".  So add NULL/0 stubs for pointers/values.

gdb: constify remote files_info

The sim and m32r remote targets declare a local "file" variable and only
assign const strings to it before passing it to a printf() func.  So add
const markings to avoid gcc warnings like:
gdb/remote-sim.c: In function 'gdbsim_files_info':
gdb/remote-sim.c:789: warning: initialization discards qualifiers
from pointer target type

sim: constify dup_arg_p

The dup_arg_p function is only given const strings, and it maintains a
local table of those const strings.  So constify the whole thing to fix
the GCC warnings:

common/sim-options.c: In function 'sim_parse_args':
common/sim-options.c:559: warning: passing argument 1 of 'dup_arg_p'
discards qualifiers from pointer target type
common/sim-options.c: In function 'print_help':
common/sim-options.c:675: warning: passing argument 1 of 'dup_arg_p'
discards qualifiers from pointer target type

I've committed the following patch as obvious.  The local "prefix"

sim: constify save_data()

The local save_data() function takes a pointer to a buffer and only uses it as
the source to the memcpy() function.  Since it is given const strings, GCC
likes to spit out warnings:
common/sim-trace.c: In function 'trace_prefix':
common/sim-trace.c:697: warning: passing argument 5 of 'save_data' discards
qualifiers from pointer target type

outputs the warnings:
common/sim-options.c: In function 'standard_option_handler':
common/sim-options.c:271: warning: assignment discards qualifiers from pointer
