TEMPORARY_DISABLE_PATH_RESTRICTIONS has been removed,
and path tools are no longer allowed to be invoked in
the Android build. This patch allows the kernel build
works fine in context of these restrictions.

1. Save and revert the timestamp of KERNEL_USR to the creation of kheaders
file to avoid re-compilation of external/vendor modules during
no-operation incremental build due to dependency on KERNEL_USR rule.

2.Avoid deletion and re-creation of the symlink in the KERNEL_OUT rule.

3. De-couple KERNEL_USR timestamp from KERNEL_OUT and KENREL_HEADERS_INSTALL
target rules.

Add qca_cld3_qca6390 wlan driver in module blocklist.
The driver for qca6490 will be loaded via init.target.rc
script hence added in module blocklist to avoid the loading
via vendor_modprobe script.

Add support for modules_prepare for preparing kernel for compiling
external modules in parallel. This helps in saving complete android
build time of 10-15 minutes approximately as external modules are
compiled early on without waiting for the kernel image to compile first.

generate_defconfig.sh uses the TARGET_BUILD_VARIANT env variable to
determine if DEBUG_FS has to be enabled or not. Hence, explicitly
set this in generate_defconfig.sh's environment for it to take
effect.

The build system doesn't seem to trigger the target
to build the GKI kernel, thus leading to inconsistent
builds. Hence, add a make target dependency on creating
a GKI_OUT directory to force building GKI kernel.

starts first it needs the ufdt_apply_overlay host tool present.

For $(PLATFORM)-qgki_defconfig, currently we build GKI and QGKI
kernels in a serial manner. To improve the build time, build the
kernels in parallel. For this, remove the 'make' target dependencies
between the two kernel builds and make sure that the defconfigs
for both the kernels are generated in sequence.

Modprobe doesn't differenciate between '-' and '_'. That is, the
output of 'modprobe -l' returns module names with '_' even though
the .ko file has '-' in the name. Since we compare this output
with the file name to check if the file is actually blocklisted in
vendor_modprobe script, we fail. Hence, convert all the module names in
the blocklist file to '_'. This change won't affect the modprobe -b.

modules not to insert into the kernel, rename the modules.blacklist file

For the sake of GKI compliance testing, QGKI and GKI should be sharing
the same vendor.img and vendor_boot.img. Hence, the idea is to build
the GKI kernel along with QGKI such that the modules could be packaged
accordingly.

Modprobe converts every hyphen in the name of a module to underscore.
Debugging such modules with names having hyphen in t32 simulator, gave
an error of module not found. So, rename all modules in unstripped folder
by replacing all hyphens in the name to underscores.

Currently, the build script installs the modules by stripping off
the symbol information, which further then gets placed on the target.
However, this symbol information is really useful for performing
postmortem analysis. Hence, install a separate copy of unstripped
modules for this purpose.
