ffi: turn char conversion flags into enum.

The three flags controlling character array conversion
semantics are mutually exclusive. Let's turn them into an
enumeration, so we can (1) test that a conversion is in effect
by testing a single value and (2) switch on the conversion
type instead of successively testing the flags and (3) assure
the aforementioned mutual exclusion.

* ffi.c (enum char_conv): New enum.
(struct txr_ffi_type): Members char_conv, wchar_conv and
bchar_conv gone, replaced by ch_conv.
(ffi_array_in, ffi_array_put, ffi_array_out,
ffi_array_get_common, ffi_array_release_common,
ffi_varray_null_term_get, ffi_type_compile,
carray_ensure_artype): Work with ch_conv instead of three
flags.
