Allow low memory to be returned when highmem pages are requested to avoid this loop.

This will allow platforms to provide (for example) a region of low memory and a region of high memory. The maximum possible number of extra regions is 128 (== E820MAX) which is quite large so xen_extra_mem is placed in __initdata. This is safe as both xen_memory_setup() and balloon_init() are in __init. The balloon regions themselves are not altered (i.e., there is still only the one region).

This reduces the domain's current page count in the hypervisor. The Xen balloon driver does not correctly decrease its initial current_pages count to reflect this. If 'delta' pages are released and the target is adjusted the resulting reservation is always 'delta' less than the requested target. This affects dom0 if the initial allocation of pages overlaps the PCI memory region but won't affect most domU guests that have been setup with pseudo-physical memory maps that don't have gaps. Fix this by accouting for the released pages when starting the balloon driver. If the domain's targets are managed by xapi, the domain may eventually run out of memory and die because xapi currently gets its target calculations wrong and whenever it is restarted it always reduces the target by 'delta'.
