c64a3eaf92 Improvements to BSD-licensed DTC.
- Added an expression parser so that expressions from headers are now working
- Fixed missing null terminators on cross references
- Disabled exceptions / RTTI in the build for smaller binaries
- Changed phandle order generation to be identical to GPL'd dtc

b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

a0706eb457 Lots of improvements to the BSD-licensed dtc
- Various fixes to includes (including recursive includes)
- Lots of testing that the output exactly matches GPL'd dtc
- Lots of bug fixes to merging
- Fix incorrect mmap usage
- Ad-hoc memory management replaced with C++11 unique_ptr and similar

Patrick Wildt has successfully run many (all?) of the GPL dtc test suite.

7f78c17319 dtc: ignore lines starting with #.
This is necessary because we use the C pre-processor to parse #include lines
and cpp adds line markings that start with #.

e29c18df28 Add a checker to dtc, based on a feature request from rwatson / brooks.
This checks that every node that has children specifies their register sizes.
This is not enabled by default, as the default sizes are sometimes required
(including by some DTS in the tree), but can help when writing new device
trees so that you can check that you actually meant the defaults.

af0dd31fc4 Import new (BSDL) device tree compiler. Now built by default, so that it can't
be used on the host system (and not installed on the device, if required).  The
GPL'd one is still available if there are any devices that need it (make
universe passes with it, including kernels that use fdt, but there may be some
out-of-tree ones).  WITH_GPL_DTC can be used to select the old one, for now.

Probably won't be MFC'd, but we'll remove the GPL'd version in head after the
new one has had a lot more testing and ship it in 10.0.
