emalloc() is called only by construct_mbi() during creating e820 mmap
layout. The switching has two benefits: first, UEFI FW might keep some
memory in pool, unlike call to emalloc(), call to allocate_pool() might
have no impact on e820 mmap; on the other hand, we can remove emalloc()
routine after this switching.

To reduce the call to dynamic memory allocation, the patch tries to
alloate memroy together with hypervisor when hypervisor is being
relocated by efi stub code. The memory allocated will be right at the
end of HV memory. Three structs will be done in this way: 1) boot_ctx,
which saves EFI boot state and is passed to SOS; 2) multiboot_info,
faked multi-boot header for passing boot info to hypervisor; and 3)
multiboot_mmap, e820 mmap structure.
after this, the EFI stub code (which boot hypervisor) will only have 3
to dynamic memory:
1. the call for hv binary and the 3 struct;
2. the call to CPU boot trampoline code;
3. the call to alloc mmap buf when inquery memory layout from UEFI FW;

This patch drops the following useless files in the hypervisor:

config.h") these headers are obsolete for configuration. Drop the directories
and move the generated version.h under $(HV_OBJDIR)/include.

2. 'make RELEASE=1' is backward-compatible and enforces a release version to be
