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.

If the MAX_MSIX_TABLE_NUM is specified in scenario.xml. Return the
largest number from count of MSI, table_size of MSIX or
MAX_MSIX_TABLE_NUM of scenario.xml.

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.

It is a common practice to parse PCI BDF in the static allocators. This
patch moves the BusDevFunc class (which is a named tuple encoding a BDF) to
lib.py and uses it for BDF parsing throughout the static allocators.

Configure PTM in post-launched VM using <PTM> element. If the //vm/PTM
sets to 'y', pci_dev.c.xsl appends the virtual root port to
corresponding struct acrn_vm_pci_dev_config of that VM. Currently it
supports only post-launched VMs.
Configure enable_ptm for dm argument. If a uos/enable_ptm with uos id
= 'vm_id 'sets to 'y' and the vm/PTM with the same vm_id sets to 'y',
append an "enable_ptm" flag to the end of passthrough ethernet devices.
Currently there is only ethernet card can support the "enable_ptm"flag.
For the schema validation, the <PTM> can only be ['y', 'n'].
For the launched script validation, the <enable_ptm> can only be ['y',
'n']. If the <enable_ptm> sets to 'y' but the corresponding <PTM> sets
to 'n', the launch script will fail to generate.
