- Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in
arch_limits.h so as to permit getting them from there without
pulling all the internal Mini-OS defines.
- Setup a xen-elf cross-compilation environment in stubdom/cross-root
- Add a POSIX layer on top of Mini-OS by linking against the newlib C
library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c
- Cross-compile zlib and libpci too.
- Add an xs.h-compatible layer on top of Mini-OS' xenbus.
- Cross-compile libxc with an additional xc_minios.c and a few things
disabled.
- Cross-compile ioemu with an additional block-vbd, but without sound,
tpm and other details. A few hacks are needed:
- Align ide and scsi buffers at least on sector size to permit
direct transmission to the block backend. While we are at it, just
page-align it to possibly save a segment. Also, limit the scsi
buffer size because of limitations of the block paravirtualization
protocol.
- Allocate big tables dynamically rather that letting them go to
bss: when Mini-OS gets installed in memory, bss is not lazily
allocated, and doing so during Mini-OS is unnecessarily trick while
we can simply use malloc.
- Had to change the Mini-OS compilation somehow, so as to export
Mini-OS compilation flags to the Makefiles of libxc and ioemu.

If a thread tries to sleep from a callback or with callbacks disabled,
Mini-OS will completely lock, so make sure this never happens.

As it may compete with event handlers waking wait queues, wake_up
needs to be callback-safe.

One may want to use semaphores in event handlers to wake threads
waiting for a resource, so semaphores then need to be callback-safe.

Make bind_virq() return the port bound to the irq, which is useful
e.g. for masking/unmasking it.

Fix x86 arch_switch_thread by making it pure assembly.
There were missing general register clobbers for x86_64, and BP should
theorically be clobbered too, but gcc does not believe that, so the
only simple safe solution is to use pure assembly.
