add support for -Wmemcpy-max-count
sparse will warn if memcpy() (or memset(), copy_from_user(),
copy_to_user()) is called with a very large static byte-count.
But this warning is given unconditionaly while there are projects
where this warning may not be not desired.
Change this by making this warning conditional on a new warning
flag: -W[no-]memcpy-max-count
