Use memops for mem paging, sharing, and access, instead of domctls
Per page operations in the paging, sharing, and access tracking subsystems are
all implemented with domctls (e.g. a domctl to evict one page, or to share one
page).
Under heavy load, the domctl path reveals a lack of scalability. The domctl
lock serializes dom0's vcpus in the hypervisor. When performing thousands of
per-page operations on dozens of domains, these vcpus will spin in the
hypervisor. Beyond the aggressive locking, an added inefficiency of blocking
vcpus in the domctl lock is that dom0 is prevented from re-scheduling any of
its other work-starved processes.
We retain the domctl interface for setting up and tearing down
paging/sharing/mem access for a domain. But we migrate all the per page
operations to use the memory_op hypercalls (e.g XENMEM_*).

explicit pod lock: per p2m, order enforced.
Three consequences:
- Critical sections in the pod code protected by the page alloc
lock are now reduced to modifications of the domain page list.
- When the p2m lock becomes fine-grained, there are no
assumptions broken in the PoD layer.
- The locking is easier to understand.

The lock is not taken for shadow lookups. We believe there are no problems

xenstored: use grant references instead of map_foreign_range
make xenstored use grantref rather than map_foreign_range (which can
only be used by privileged domains)
This patch modifies the xenstore daemon to use xc_gnttab_map_grant_ref
instead of xc_map_foreign_range where available.

mini-os: make frontends and xenbus optional
This adds compile-time logic to disable certain frontends in mini-os:
- pcifront is disabled by default, enabled for ioemu
- blkfront, netfront, fbfront, kbdfront, consfront are enabled by default
- xenbus is required for any frontend, and is enabled by default
If all frontends and xenbus are disabled, mini-os will run without
needing to communicate with xenstore, making it suitable to run the
xenstore daemon. The console frontend is not required for the initial
console, only consoles opened via openpt or ptmx.

Instead of using CONFIG_QEMU and CONFIG_GRUB to enable or disable minios

The configuration flags are currently added to the compiler command
line; as the number of flags grows this may need to move to a header.
