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.

print out const or volatile qualifiers, too.
(c_type_print_args): Add parameters show_artificial and language.
Skip artificial parameters when requested.
Use the appropriate language printer.
(c_type_print_varspec): Tell c_type_print_args to skip artificial
parameters and pass language_c.
