As pointed out by Sandra Loosemore, a bunch of targets define sim_write
themselves instead of using the common/ code. So constify them too.

New variables.

A few ports rely on internal dv-sockser state in order to detect whether
a connection has been made (look for 'extern sockser_addr'). Rather than
continuing that tradition, extend the existing status function to return
the socket connection status.

Most the sim write functions declare their source buffer const because
they only ever read from it. The global sim_write() function does not
follow this convention though which causes some warnings when trying to
pass it const strings or buffers.

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.

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.

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

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