Added __repr__ implementation, initialise last_login_method to None, and
use gettext's ugettext explicitly, rather than using gettext.install. These
things together improve the error messages that you get when using this
module incorrectly in the interactive interpreter.

Do not update the PV_ variables with the values outputted by the bootloader --
this gets us into all sorts of trouble when Xend is restarted and then the
domain is rebooted, because we expect to be able to handle the PV_kernel == ''
case by defaulting to pygrub.
[HVM] Route ISA IRQ 0 to IOAPIC GSI 2, just like 99% of native systems.
This is a built-in assumption of HPET 'legacy' IRQ routing, which is
why we have changed to this routing strategy now.

Change the way that networks and PIFs relate to each other -- the PIF holds a
reference to the network (and the host) not the other way around. Persist only
the necessary details for the network (not the set of PIFs and VIFs).
Fix the plumbing of the network class inside XendAPI, and implement a few more
functions.

out of the exception) and tidy up the validator preprocessing and the
validators themselves.

Added Xen-API-style error handling for INTERNAL_ERROR and

XML-RPC server, not to the legacy one.

Move the decoration of all the Xen-API methods out of XendAPI.__init__ and
into the module scope. This avoids the decorators being added multiple times,
once for each server running.
Fix handling of MESSAGE_PARAMETER_COUNT_MISMATCH in many cases. Move the
get_by_uuid declarations, so that those functions get the per-class validator
as well, to check for existence of the object requested.

[LINUX] dma: Use swiotlb mask for coherent mappings too
The recent change to use a default DMA bit width of 30 bits (required
by chips like the b44) only converted the streaming DMA primitives.
The coherent mappings are still hard-coded to 31 bits. This means
that b44 still doesn't work under Xen.
This patch makes the io_tlb_dma_bits variable global and uses it for
coherent memory mappings.
Thanks to Calvin Webster for providing a machine with a b44 and 2G
of memory I've been able to verify that this finally makes the b44
work under Xen.

Rename 'io_tlb_dma_bits' to the more correct 'dma_bits'. This also
affects the name of the boot parameter, which is now 'dma_bits='.

[HVM][SVM] Modify the interrupt/event injection logic.
Resolves performance issues concerning AMD-V virtual interrupt/event
injection:
- Remove extra VINTRs vmexits, and only setup fake interrupt if intr
pending.
- Allow both event injection and interrupt injection concurrently in
vmcb.
Since we had changed to use event callback to deliver interrupts,
1. The pending_interruption is changed to pending_event.
2. get_ivr, set_tpr, get_trp and set_eoi are not used or only used
in the initialization phase. There is no need to write this code
in assembly. This code is deleted.
3. hyper_ssm_i needs to be rewritten to jump to entchn_callback_handler
instead of iva+0x3000 interrupt handler. I will do this later.
