Move hvm platform timers from underlying physical CPU TSC to Xen
system time and ensure domain-wide monotonicity. TSC on many systems
may skew between processors leading to 'time going backwards' messages
from some guests.

F10 to select boot device. This will be rarely used, and it is
possible to hit F10 before the message is displayed and the keypress
will still register. So in practice it is quite possibel to use this
boot feature reliably without needing a multi-second delay.

In xen/arch/x86/cpu/amd.c the function disable_c1_ramping iterates
over the northbridges using NR_CPUS as an upper bound for the number of
nodes. If there are no more northbridges found, it stops iterating.
Sadly it just adds the northbridge number to 0x18 and uses this as a
PCI device number, so probing the 9th northbridge on an 8 node system will
be caught by the newly inserted assertion in pci_conf_read in current
unstable. We fix this by first querying the number of nodes from the
first northbridge to avoid the overflow.

This patch adds -s --ssl option to xm migrate. It will override
xend-relocation-ssl setting in /etc/xen/xend-config.sxp.
When mix deploy xen 3.2 and xen 3.3 servers, it's convenient to have a
command line option rather than modify /etc/xen/xend-config.sxp every
time.

This patch makes ssl relocation server listen on 8003 if enabled.
Whether to start ssl relocation server now controlled by
xend-relocation-ssl-server. So ssl and non-ssl relocation server can
run simultaneously. You can also only start ssl server or only start
non-ssl relocation server.
When mix deploy xen 3.2 server (has no ssl support) and 3.3 servers,
start ssl and non-ssl relocation server simultaneously can keep
backward compatibility.
It's also more reasonable to have separate ports for ssl and non-ssl.
In this patch, also renames xend-relocation-tls to xend-relocation-ssl.

The automatic NUMA placement code (find_relaxed_node) in
XendDomainInfo.py contains several bugs:
1. The domain just created shall not be considered in the load
calculation.
2. Nodes with too less memory for the domain must be considered during
the load calculation phase and abandoned later, currently these nodes
win with a load of 0.
3. CPUs which are offline shall not be considered in load calculation.
4. (Integer-)Dividing the load value by the number of cores per node
may conceal subtle load differences resulting in a non-optimal node to
be chosen.

- add S3 package in ACPI DSDT table. Guest OS will get S3 value from
this package and write the value to PM1A control register to
trigger S3 suspend.
- Add S3 resume logic in rombios post code. the CMOS shutdown register
is used to indicate if this is a S3 resume.
- if it is s3 resume, rombios will get wakeup vector from ACPI FACS
table and jump to wakeup vector. Per ACPI spec, the wakeup vector
jumping must be the forms CS:IP, in which CS=3D(wakeup vector>>4)
IP=3D(wakeup vector)&0xF, for example, for vector=3D0x12345,
CS:IP=3D0x1234:0x5
Note: clobber_entry_point will clobber the post entry, which make S3
resume not work. We will directly jmp to POST Entry if it in S3
Resume path.

Changeset 17289:d97e61001d81: introduced vfb configuration parameter
videoram, defaulting to zero. Value zero was interpreted as
unlimited. Changeset 17630:53195719f762 accidentally dropped the
special case for zero, which broke guests that don't specify videoram,
or specify videoram=0. Restore the old behavior.
