Status of the langtools repo in the build-infra forest

[Magnus Ihse Bursie]

Similar to hotspot, the langtools repo has also been messy. The reason 
for this is basically that it contains two kinds of changes, Fredriks 
smartjavac implementation, and changes to the new buildsystem. On top of 
that, Fredrik has pulled some fixes from the tl forest, while Kelly, 
Erik and I have pulled from the build forest.

The smartjavac changes will have to be integrated via langtools, but the 
buildsystem stuff should go via build.

On top of that, there is a third change, which is a modification to 
test/Makefile to adapt to running tests via build-infra. I have 
published a separate webrev for that change. It is non-essential, 
however, so if it turns out to be problematic, we can just drop it.

Currently, the only build-infra changes are minimal, it's a few lines of 
changes log level, a changed filename and new top-level wrapper similar 
to those in the other repos. However, due to the filename change, the 
actual change is hard to see. Here it is for your benefit. This info 
should probably be attached when the formal request for a code review 
turns up.
