Use gdb_byte for bytes from the program being debugged.

gdb_byte should be used for bytes from the program being debugged.  We
have many places using char or unsigned char instead all over the
existing ports, and more ends up added over time due to copy/paste as
new code is based on old code.

I've greped the tree for "char buf[", and fixed all I found.

Tested by building with --enable-targets=all.
