[XEND] separate concept of initial memory size and overhead memory size.
When a domain (whether para- or fully-virtualized) reports how much
overhead memory it requires (via getDomainMemory in image.py), all such
memory was immediately allocated to the domain itself. This is
certainly incorrect for HVM domains, since additional
increase_reservation calls are made later in qemu. Since all ballooned
memory is already taken, qemu will fail. The fix is to treat the
requested memory size and the overhead size as separate values. The
requested memory size is immediately allocated to the new domain; the
overhead is left unallocated for whatever else might need it later.

* oprofile_set_active() calls set_active() method without holding

the middle of xenoprof_set_active().
* adomain_write(), adomain_read() and xenoprof_set_active() access
global active_domains[] and adomains without synchronization. I
went for a simple, obvious fix and created another mutex. Instead,
one could move the shared data into oprof.c and protect it with
start_sem, but that's more invasive.
Also clean up the code dealing with /dev/oprofile/active_domains:
* Use parameters instead of global variables to pass domain ids
around. Give those globals internal linkage.
* Allocate buffers dynamically to conserve stack space.
* Treat writes with size zero exactly like a write containing no
domain id. Before, zero-sized write was ignored, which is not the
same.
* Parse domain ids as unsigned numbers. Before, the first one was
parsed as signed number.
Because ispunct()-punctuation is ignored between domain ids, signs
are still silently ignored except for the first number. Hmm.
* Make parser accept whitespace as domain separator, because that's
what you get when reading the file.
* EINVAL on domain ids overflowing domid_t. Before, they were
silently truncated.
* EINVAL on too many domain ids. Before, the excess ones were
silently ignored.
* Reset active domains on failure halfway through setting them.

Fix the cirrus vga model to not leak memory when switching between
initial vga mode and linear framebuffer.
When creating device model, the vga memory is allocated through
xc_domain_memory_increase_reservation(), however, when switch to use
linear framebuffer, we didn't free that memory, and re-allocate the vga
memory through set_mm_mapping(), that caused memory leak. Now it is
changed to just using qemu_malloc when create device model, and free
that memory when switch to linear framebuffer.
After unset_vram_mapping(), the old memory pointer should be
unmapped; after set_vram_mapping(), the old memory should be freed.

Add support to domain builders for loading kernels with physical addresses in the elf paddr and entry fields.
Add a new __xen_guest header field to distinguish between kernels with
the previous use of the paddr field and the new use.
Add a new __xen_guest header field to control the kernel entry point,
since the elf header entry field now points to a physical address.
This header field is also useful for supporting alternative entry
points in kernel images which run both on xen and native.
Also add a kernel config option to control whether the resulting kernel
should include compatibility code to run on Xen 3.0.2 or whether such
code such be left out, resulting in a kernel which will only run on
newer Xen versions. Default to having compatibility enabled.
Kernels built with the new use of the elf header fields would otherwise
not work on Xen versions prior to this changeset.

If you change the video resolution on a Windows XP guest such that it uses
