I think this LIBXL_MAXMEM_CONSTANT should be pushed to your helper
function, too.

So that, we can have all LIBXL_MAXMEM_CONSTANT removed in libxl
functions (see libxl.c and libxl_dom.c)

If we push LIBXL_MAXMEM_CONSTANT to the libxl_arch_memory_constant and remove it from libxl.c, do we need to call libxl_arch_memory_constant there in libxl_set_memory_target()?
