Fix -Wpointer-sign around strings/encoding conversions.
Trimmed for brevity:

As with the previous patch, the encoding conversion code works with
gdb_byte arrays as the generic buffers that hold strings of any
encoding/width. This patch adds casts where appropriate.

2013-03-07 Pedro Alves <palves@redhat.com>
* c-lang.c (parse_one_string): Cast argument to gdb_byte *.
* expprint.c (print_subexp_standard): Likewise.
* utils.c (host_char_to_target): Likewise.
* valprint.c (generic_emit_char, generic_printstr): Likewise.
* varobj.c (value_get_print_value): Change type of local to char*.
Cast it gdb_byte * in call to language printer.
