The interrupt pin descriptors in board XML follows the same notation as in
ACPI PRT (PCI Routing Table), i.e. either an integer or a pair of a device
object and an index.
However, the current static INTx allocator recognizes
integer-as-interrupt-line only, which will cause build-time failure if
the "device object + index" notation is used in physical DSDT to describe
PCI interrupt pin routing.
This patch refines the static allocator so that both notations can be
parsed properly. In case an interrupt line descriptor in the board XML
refers to an device object without an index, it is interpreted as the first
of the ACPI device object if it is an interrupt resource.

Remove the restriction that SERIAL_CONSOLE needs to be ttys0, ttys1,
ttys2 or ttys3.
1. Lossen the restriction in xsd.
2. Rewrite the document.
3. Refine the intx.py. Refine the logic which take effect if the <irq>
is specified in "SOS_COM#_IRQ" for SOS VM's legacy vuart 0.

Expand the capacity of legacy vuarts per VM. This change is applied to
manual scenario xml editing only.
A SOS VM can choose io port 0x3F8, 0x2F8, 0x3E8, 0x2E8 by selecting
SOS_COM1_BASE, SOS_COM2_BASE, SOS_COM3_BASE, SOS_COM4_BASE respectively.
Non SOS VM can choose io port 0x3F8, 0x2F8, 0x3E8, 0x2E8 by selecting
COM1_BASE, COM2_BASE, COM3_BASE, COM4_BASE respectively.
For any type of VM, selecting "CONFIG_COM_BASE" allows configuration tool
to pick an available io port from hardcoded list:
['0xA000', '0xA010', '0xA020', '0xA030', '0xA040', '0xA050', '0xA060', '0xA070']
A SOS VM can choose irq 4 by selecting SOS_COM1_IRQ and SOS_COM3_IRQ, and choose irq 3 by selecting SOS_COM2_IRQ and SOS_COM4_IRQ.
Non SOS VM can choose irq 4 by selecting COM1_IRQ and COM3_IRQ, and choose irq 3 by selecting COM2_IRQ and COM4_IRQ.
For SOS VM, selecting "CONFIG_COM_IRQ" allows configuration tool
to pick an available irq based on AVAILABLE_IRQ_INFO. For non SOS VM, it
will allocate an available irq from [1, 15].

There could be multiple ways in the scenario configuration to specify that
no INTx allocation is explicitly allocation to a prelaunched VM:
* Do not have a `pt_intx` node at all.
* Have a `pt_intx` node with no text.
* Have a `pt_intx` node with a text that has nothing but whitespaces,
tabs and newlines.
The current implementation only supports the first way, and will cause
build-time failures when a scenario configuration uses the latter two. The
following changes are introduced by this patch to fix such errors.
* The INTx static allocator queries the text() of `pt_intx` nodes
directly to gracefully handle `pt_intx` nodes with no text.
* The XSLT of pt_intx.c clears all kinds of white spaces from the text of
`pt_intx` nodes before calculating the set of allocated INTx mappings.

This patch allocates interrupt lines among VMs according to the PCI devices
assigned to them.
v1 -> v2:
* Remove the usage of VMx_PT_INTX_NUM macro in vm_configuration.c; use the
concrete numbers directly.
* The static allocator will also complain if any interrupt line is allocated to
a VM with LAPIC_PASSTHROUGH.
v2 -> v3:
* Fix a minor coding style issue.

Create an intx.py which is a static allocator to allocate the irq
resources. The available irq list is based on the native irqs which
are in range [0, 15] and are not used by native os.
