Do all remaining changes necessary for a working build.
Add Makefile.am files in include/... subdirs.
Remove noinst_HEADERS directives from src/*/Makefile.am, but keep the headers
list to feed to move-asn1-header-files.sh.
Adjust all #includes in src/*_common.h and elsewhere. In hnbap_common.h,
separate the ASN.1 "primitive" headers from the others, and include them
without a subdir path, as before.
We now have the RUA and SUA parts interconnected by the
context ID mapper, and should be able to pass messages back and forward
between both sides.
Unfortunately this touches a bit of everything, but the structures are
all still very much in flux. Hopefully they will start to stabilize at
some point soon...
encoding correctness still needs to be verified at this point. At least
they generate some binary output without failing somewhere earlier in
the encoding process - and they don't leave any leaked memory behind,
see talloc_report() at the end of test-ranap.c:main().
