This patch makes the build system of the hypervisor to cache the board and
scenario XML files in the build directory and generate C configuration
files from them at build time. The C configuration files that are cached in
the git repo is no longer used or updated. Paths to these generated files
in the prebuild Makefile is updated accordingly.
The following targets are introduced or modified.
* defconfig: Copy default configuration XMLs to the build directory and
generate C configuration files.
* oldconfig: No action.
* menuconfig: Print a message to redirect users to use the config app
and exit.
* showconfig: Print the BOARD, SCENARIO and RELEASE configured for the
current build.
* update_config: No action.
* (default): Build the hypervisor with defined configurations.
The following variables can be set on the command line to specify the
default configuration to be used.
* BOARD: Either a name of the target board or a path to a customized
board XML. When a board name is specified, the board XML file
is expected to be available under
misc/acrn-config/xmls/board-xmls.
* SCENARIO: Either a name of the scenario of a path to a customized
scenario XML. When a scenario name is specified, the
scenario XML file is expected to be available under
misc/acrn-config/xmls/config-xmls/$(BOARD).
* BOARD_FILE: Path to the board XML file to be used. This is now
obsoleted as BOARD provides the same functionality.
* SCENARIO_FILE: Path to the scenario XML file to be used. This is now
obsoleted as BOARD provides the same functionality.
BOARD/SCENARIO or BOARD_FILE/SCENARIO_FILE shall be used in pair, and
BOARD_FILE/SCENARIO_FILE shall point to valid files when specified. Any
violation to those constraints will stop the build with error
messages. When BOARD/SCENARIO and BOARD_FILE/SCENARIO_FILE are both defined
on the command line, the former takes precedence as the latter are to be
obsoleted.
Additionally, users can define the RELEASE variable to specify a debug or
release build. In case a previous build exists but is configured for a
different build type, the build system will automatically update the
scenario XML and rebuild the sources.
This patch also includes the following tweaks:
1. Do not use `realpath` to process search paths for generated
headers. `realpath` only accepts paths of existing files, while the
directories for generated headers may not be created at the time the
search paths are calculated.
2. Always expect `pci_dev.c` to be in place.
3. HV_CONFIG_* series now encodes absolute paths.
v3:
* Do not validate BOARD_FILE/SCENARIO_FILE if BOARD/SCENARIO are given.
v2:
* `defconfig` now also generates the C configuration files.
* BOARD/SCENARIO now accept either board/scenario names or XML file paths.
* Adapt to the new allocation.xml & unified.xml.
* Cleanup names of internal variables in config.mk for brevity.

Move struct pt_intx_config vm0_pt_intx[] defintion to pt_intx.c
so that vm_configurations.h/vm_configurations.c are consistent for different boards

This patch will move the VM configuration check to pre-build stage,
a test program will do the check for pre-defined VM configuration
data before making hypervisor binary. If test failed, the make
process will be aborted. So once the hypervisor binary is built
successfully or start to run, it means the VM configuration has
been sanitized.
The patch did not add any new VM configuration check function,
it just port the original sanitize_vm_config() function from cpu.c
to static_checks.c with below change:
1. remove runtime rdt detection for clos check;
2. replace pr_err() from logmsg.h with printf() from stdio.h;
3. replace runtime call get_pcpu_nums() in ALL_CPUS_MASK macro
with static defined MAX_PCPU_NUM;
4. remove cpu_affinity check since pre-launched VM might share
pcpu with SOS VM;
The BOARD/SCENARIO parameter check and configuration folder check is
also moved to prebuild Makefile.
