[OE-core] [PATCH 0/3 V3b] Enable building modules on target

[Darren Hart]

Note: As this is a major change that impacts every BSP, I suggest this
      spend some time in MUT before being included into master.

This series adds support for building modules on the target via an expanded
kernel-dev package.

Sending to both oe-core and poky as this series touches files in both
and I didn't want to confuse the intent or the dependency by splitting
them up (at least the original did, keeping it consistent).

V2:
o Add files to kernel-dev rather than create a new kernel-headers package
o Move the location to /usr/src/kernel from /usr/src/kernel-headers
o Eliminate the kernel-misc package as kernel-dev covers it now
o Fix a bug with linux-yocto-custom exposed during testing

V3b:
o Rebase on origin/master where 2 patches had already been applied
o Correct the bitbake.conf STAGING_KERNEL_DIR path which I missed in V2
o Move kernel-dev inclusion from task-core-sdk to the core-image*sdk recipes
  in order to avoid making task-core-sdk machine specific
o Kill the kernel_package_prepend() function which deleted the kernel headers
o Add a KERNEL_SRC_DIR variable to avoid missing one of the many hard-coded
  paths during an update

Testing Performed:
Built core-image-sato-sdk, core-image-lsb-sdk, and core-image-rt-sdk for
qemux86 and built the kernel scripts with:

  # make -C /usr/src/kernel scripts

For sato-sdk and lsb-sdk, copied over the hello-mod module sources and built the
hello-mod module on the target, insmod, rmmod, dmesg -n 2.  The output was
correct. rt-sdk didn't have dropbear or feasible way to quickly copy the files
across, but I'm confident knowing the scripts built.
