Add a new console interface using a seperate shared page and event channel
instead of passing the console input/output over control messages.
Update xenconsoled to use the new console interface.
Make xenconsoled garbage collect dying domains by subscribing to
the domain exception virq.

guest to BUG() on resume when trying to request its callfunc_irq. Plus a
few small cosmetic changes.

/bin/bash: ❌ command not found
The for_each_cpu_mask macro has a slightly odd behaviour in the
non-CONFIG_SMP case, making the code unexpectedly incorrect.

This should fix the assertions people have been seeing
in domU blkfront where we run out of IDs (because they
were being shared by multiple vbds).

all register parameters are clobbered on return. Furthermore,
multicall arrays are clobbered on return from a multicall (only the
result field can be trusted!).
These restrictions are enforced by debug builds of Xen in the
following ways:
1. On completion of a multicall, the call array is overwritten
with garbage before writing in the result fields.
2. On completion of a hypercall, all parameter registers are
overwritten with garbage.

unpin", which is already implemented for x86_32. Since we now only pin
the root rather than any of the other levels, the overall performance
became better especially with workloads that require heavy memory
management operations.
On 8-way x86_64 xenlinux (dom0) the kernel build was improved by about
10% (using make -j32). Even a small setup like a UP HT system, I see
about 3% performance gain with kernel build (make -j4).
Lmbench also shows improvements in fork/exec/sh:

Fix the tools/vnet makefiles so that vnets will compile
and includes updates to the vnet implementation.
Vnet ids are increased to 128 bits. The vnet module will
insmod whether xen-br0 exists or not.

The removal of 'xm call' to call a xend interface function directly
made the xend vnet functions inaccessible. This patch adds those functions
to xm and fixes the persistence in XmVnet to use xenstore.

Use a collector and new flag for Xen version information, to avoid the
extra hypercall if the caller does not want the information.
Reference the xenstat_handle in the xenstat_node for ease of access
later, and update collectors accordingly.
