Use the notation suggested by Martin Jansa to avoid a bashism. Also
switch KERNEL_DTBVENDORED to the more common 0/1 notation instead of
true/false.

Fedora/Redhat and Arch are somewhat standardized on their dtb directory
structure. Let's add some flags to configure yocto to mimic that
behavior.
Add the following variables to the kernel class:
- KERNEL_DTBDEST (controls the destination directory for dtbs)
- KERNEL_DTBVENDORED (controls if vendor subdirectories are to
be respected)
Currently KERNEL_DTBDEST is expected to be a subdir of KERNEL_IMAGEDEST
and KERNEL_DTBVENDORED is expected to be "true"/"false". This only
applies to the package directory structure. The deploydir structure is
purposely left untouched for compatibility with existing recipes.
By default this is configured to behave the same as the current recipe
and produce a flat dtb directory at KERNEL_IMAGEDEST.

This is a partial fix for bugzilla 15059 [https://bugzilla.yoctoproject.org/show_bug.cgi?id=15059]
It has been noted by several people that when an initramfs is bundled:
- a lot of the kernel is rebuilt
- it takes a really long time
When looking at the logs, the second kernel compilation (that performs
the bundle) is not using the parallel make settings, and builds with
-j1.
We are already explicitly passing PARALLEL_MAKE when building kernel
modules, and by extending that explicit use to the main kernel
compilation, we ensure that we always get a parallel build.
Build times chnaged from more than 30 minutes for the bundle, to
3 minutes in local testing.
The question of whether or not too much is rebuilding during the
bundle step is still an open question, but with this tweak, at least
the build time is back in the realm of acceptable.

* move it from kernel.bbclass, because it needs to stay in sync with
IMAGE_LINK_NAME structure
* image-artifact-names.bbclass is also inheritted from kernel-artifact-names.bbclass
so every recipe which needs this variable probably already inherits one of these
* fixes kernel-fitimage.bbclass with modified IMAGE_LINK_NAME

This helps in switching toolchains cleanly for kernel build
between gcc and clang
Currently, some kernels allow building with clang but not all
the distro might use clang as default system compiler but kernel
may demand gcc which is provided via KERNEL_* variables, however
kernel does use OBJCOPY at places during build and it maybe set
to use llvm objcopy when using clang. That should be a deliberate
setting when clang is used for kernel as well, otherwise it should
use binutils provided objcopy

With the 6.1 kernel we've seen reproducibility/determinism issues where the kernel
seems to rebuild headers referencing the hostname or local user. kernel-devsrc
building after the kernel seemed to trigger it in some cases.
Moving the definitions to the bbclass used by all the kernel recipe code including
kernel-devsrc seems to be the best way to ensure this doesn't happen.

As far as I can tell, none of these uses of PACKAGESPLITFUNCS need append/prepend
operators, the standard += and =+ can work just fine. Since OE-Core is copied a lot,
use the preferred syntax which is also simpler to parse and change.

Currently, the KERNEL_DEBUG_TIMESTAMPS is not working as expected
at rebuild. That is, even if we set it to "1", the kernel build time
is not changed. The problem could be reproduced by the following steps.
1. bitbake core-image-minimal; start image and check `uname -a` output.
2. set in local.conf: KERNEL_DEBUG_TIMESTAMPS = "1"
3. bitbake core-image-minimal; start image and check `uname -a` output.
It's expected that after enabling KERNEL_DEBUG_TIMESTAMPS, the kernel
build time will be set to current date. But it's not. This is because
the compile.h was not re-generated when do_compile task was re-executed.
In mkcompile_h, we have:
"""
# Only replace the real compile.h if the new one is different,
# in order to preserve the timestamp and avoid unnecessary
# recompilations.
# We don't consider the file changed if only the date/time changed,
# unless KBUILD_BUILD_TIMESTAMP was explicitly set (e.g. for
# reproducible builds with that value referring to a commit timestamp).
# A kernel config change will increase the generation number, thus
# causing compile.h to be updated (including date/time) due to the
# changed comment in the
# first line.
"""
It has made it very clear that it will not be re-generated unless
we have KBUILD_BUILD_TIMESTAMP set explicitly. So we set this variable
explicitly in do_compile to fix this issue.

It as been bothering me a bit that we don't set CC and LD consistently
for the kernel make calls and this can lead to interesting bugs as the
kernel increases in complexity. Add them to EXTRA_OEMAKE so they're
always passed in. This makes everything slightly more consistent and
less likely to break in future.
