ubldr: Bump heap size from 512K to 1M
lualoader in itself only uses another ~200K, but there seems to be no reason
not to bump it a little higher to give us some more wiggle room.
With this, I can boot using a menu-enabled lualoader, no problem and
reasonably fast. Some heap usage datapoints from the review:
forthloader, no menus, kernel loaded:
heap base at 0x1203d5b0, top at 0x1208e000, used 330320
lualoader, no menus, kernel loaded:
heap base at 0x42050028, top at 0x420ab000, used 372696
lualoader, menus, kernel loaded:
heap base at 0x42050028, top at 0x420d5000, used 544728
Since then, the no menu case for lualoader should have decreased slightly as
I've made some changes to make sure that it no longer loads any of th emenu
bits with beastie disabled.
While here, split heap size out into a HEAP_SIZE macro.
