Adds the capnproto package. This also builds a host variant to generate
the capnp compiler that can be used to compile message definitions into
C++ code. Includes a patch from upstream to fix an issue with uclibc.
The top level of the repository is not where compilation occurs, but
rather within a 'c++' folder, so the package extraction commands are
altered to only extract the c++ folder so that the rest of the autotools
framework will work correctly. Extraction also saves the LICENSE file
that was in the top-level.

This is me digging up yet another old patch...
Original v2 is here: https://patchwork.ozlabs.org/patch/787341/
Changes v2->v3:
- commit message about the package and not reiterating the help text
- changed to grab source from github, and modify extraction to get
appropriate directories
- modified patch to fix uclibc issue and point at upstream commit
- change order of dependencies to list hardware (MMU) first
Tested with test-pkg -a: 47 builds, 5 skipped, 0 build failed, 0 legal-info failed

Hi Joel,
Thanks for picking this up. Unfortunately, I have more feedback :-)

You'll have to add your own SoB here as well. Especially since you modified it.

Could you also add a hash of the license file?

You need to add a comment, like # Fetched from Github, with no configure script

This typically means that it would also depend on BR2_TOOLCHAIN_HAS_ATOMIC.
Apparently, we don't have a gcc >= 4.8 that doesn't have
BR2_TOOLCHAIN_HAS_ATOMIC in our autobuilders, so test-pkg wouldn't have captured
that.

Why does CAPNPROTO_SUBDIR=c++ not work? That would be a lot simpler.
