Add Turbine as part of java build toolchain in Make.
1. Bundle static_java_header_libs during turbine-classes.jar if
necessary. This can be improved if we have the ability to merge jars on
the fly.
2. Copy sdk/stubs-classes.jar to sdk/stubs-classes-header.jar, and Use
.KATI_RESTAT to cut un-necessary targets rebuilt.
3. Copy prebuilt-classes.jar to prebuilt-classes-header.jar since
Turbine doesn't apply to prebuilt.
4. Run jarjar after Turbine compilation, otherwise downstream targets
won't find corresponding symbols.
5. Change classes.jar in -classpath used in Desugar to
classes-header.jar.
6. Change legacy-libs in Proguard from classes.jar to
classes-header.jar.
7. Add .KATI_RESTAT for turbine-classes.jar, and remove IJAR.
8.boot.art is re-generated during the incremental rebuild since
javalib.jar got re-generated. Then boot.art re-triggered lots of
downstream targets to be rebuilt. So we add .KATI_RESTAT for javalib.jar
to prevent downstream to be rebuilt. The ziptime & commit-change-to-toc
operation for javalib.jar(small) didn't bring too much overhead when we build
from clean state.
Next step: specify static_java_header_libs in -classpath, and merge jars
at the end.
