Subject: ffi: new bstr type.

The bstr type is like str, but doesn't perform UTF-8
conversion.  The C data is assumed to be null terminated byte
strings representing code points U+0000 through U+00FF.

* ffi.c (bstr_s, bstr_d_s): New symbol variables.
(ffi_bstr_put, ffi_bstr_get, ffi_bstr_d_get): New static
functions.
(ffi_init_types): Register bstr and bstr-d types.
(ffi_init): Initialize bstr_s and bstr_d_s.

* ffi.h (bstr_s, bstr_d_s): Declared.

* lib.c (chk_strdup_8bit, string_8bit): New function.

* lib.h (chk_strdup_8bit, string_8bit): Declared.
