to export files across package boundaries.  filegroups (and genrules)
can be referenced from srcs properties of other modules using the

instead of android.BaseContext so that dependency methods can
directly add dependencies.

To date we have been using static libraries with no source files as
header-only libraries.  Switch to using header_libs to make the user's
expectations clear, in case we need to differentiate the semantics of
static libraries and header-only libraries when we enable transitive
static library dependencies.

NewLibrary is going to be used for header only libraries.  Instead
of adding more boolean arguments, replace the existing ones with
BuildOnlyStatic and BuildOnlyShared calls on the libraryDecorator
returned by NewLibrary.

LLVM has complicated static library layering that sometimes changes.
The make solution was to list all the static libraries twice, but
Soong dedups the list.  Add a group_static_libs flag to allow
surrounding the static libs with -Wl,--start-group and
-Wl,--end-group.
