- do not use gb_UnpackedTarball_copy_header_files for boost
- adapt the optimization in concat-deps.c for new path
- use boost_headers in all LinkTargets that require it
- add explicit include paths to mysqlc, mysqlcppconn, libvisio, liborcus

Boost apparently uses a MSVC auto-link feature to cause MSVC to request
a static library with a very particular name; disable this and remove
the associated ugly workarounds boost/Package_boost*.mk.
(Another alternative better than Package_boost*.mk would be to
just mangle the static library name in RepositoryFixes.mk)
