Hu Tao d42e2de7bc hostmem-ram: don't exit qemu if size of memory-backend-ram is way too big
When using monitor command object_add to add a memory backend whose
size is way too big to allocate memory for it, qemu just exits. In
the case we'd better give an error message and keep guest running.

The problem can be reproduced as follows:

1. run qemu
2. (monitor)object_add memory-backend-ram,size=100000G,id=ram0

Hu Tao bd9262d95f hostmem: separate allocation from UserCreatable complete method
This allows the superclass to set various policies on the memory
region that the subclass creates. Drops hostmem-ram's complete method
accordingly.

Igor Mammedov 1f07048933 add memdev backend infrastructure
Provides framework for splitting host RAM allocation/
policies into a separate backend that could be used
by devices.

Initially only legacy RAM backend is provided, which
uses memory_region_init_ram() allocator and compatible
with every CLI option that affects memory_region_init_ram().
