Andrew Haley found a bug on GDB running on ARM when using

sign-extends the PC. Here is a piece of his original message explaining
the problem:

Anyway, the fix is simple and Andrew himself provided it for us. It
took a while for me to figure out how to trigger the bug (in order to
write a testcase for it), but I finally made it.

The mips packet payload is ASCII, so it makes sense for
mips_send_packet and mips_receive_packet to expose 'char *'-based
interfaces, as currently they do. But, mips packets have a binary
header, so if you look at e.g., mips_receive_packet's implementation,
you'll see "unsigned char" buffers in use. I find it the most natural
to make the payload pointer passed to mips_cksum 'char *' too.
The other changes are straightforward adjustments -- a checksum is
naturally unsigned, and there's one point where we're reading a bfd section.

gdb_byte for binary buffer, char for string: remote.c, tracepoint.c.
While the RSP is largely ASCII based (hence the packet buffer type is
char *), at places we pass around 8-bit binary packets in that buffer.
Functions like hex2bin or remote_escape_output conceptually are
handling binary buffers, so I left them as working with gdb_byte, and
added casts where necessary. Whether these are host bytes or target
bytes is blurry at present, so this is largely a matter of taste.

serial_write: change prototype to take a void-pointer buffer.
While remote.c works with "char *" buffers most of the time, other
remote targets have binary-ish-er protocols, and choose to use
"unsigned char" throughout, like e.g., remote-mips.c or
remote-m32r-sdi.c. That results in -Wpointer-sign warnings in those
targets, unless we add casts in calls to serial_write. Since
serial_write is only concerned about sending raw host bytes out, and
serial_ops->write_prim already works with "void *"/"size_t", a similar
interface to the "write" or "send" system calls, I find it natural to
change serial_write's prototype accordingly, avoiding the need for
casts.

'is64' is just used as a boolean; signed/unsigned doesn't really matter.

I don't know much about s390, but from reading the code I believe the
right fix is to treat d2 as signed.

ppc-linux-tdep.c: Wrong signness for buffer holding instructions.
There seems to be no reason for this buffer to be signed. We pass it
around to functions expecting it to be unsigned (which triggers
-Wpointer-sign warnings).

mips-tdep.c: Wrong signness for local holding PC register.
Addresses on MIPS are signed, and we're indeed using
regcache_cooked_read_signed to read the PC, but, we're passing it the
address of an unsigned variable, which triggers a -Wpointer-sign
warning. I've chosen to change the variable's type. I believe this
will end up being the same (though I can't test it).
