Backport changes from 1.2.0:
configure.in,src/img.c,src/useful.c,src/useful.h: Use AC_TYPE_INT16_T
and AC_TYPE_INT32_T instead of home-brew equivalents.
configure.in,src/useful.h: On little-endian architectures, make
get16() and get32() inline functions, rather than macros which use
a global variable.
src/useful.c: Remove commented out code.
