exec: ram_block_discard_range
Create ram_block_discard_range in exec.c to replace postcopy_ram_discard_range and most of ram_discard_range. Those two routines are a bit of a weird combination, and ram_discard_range is about to get more complex for hugepages. It's OS dependent code (so shouldn't be in migration/ram.c) but it needs quite a bit of the innards of RAMBlock so doesn't belong in the os*.c.
