Sign-extend non-bit-fields in unpack_bits_as_long
unpack_bits_as_long is documented as sign-extending its result when
the type is signed. However, it was only doing sign-extension in the
case where the field was a bitfield -- that is, not when the "bitsize"
parameter was 0, indicating the size should be taken from the type.
Also, unpack_bits_as_long was incorrectly computing the shift for
big-endian architectures for the non-bitfield case.
This patch fixes these bugs in a straightforward way. A new selftest
is included.
