The end goal is to rewrite Dotty's compiler-bridge in Java (this is easy
since the zinc-specific phases are in the compiler itself) to simplify
the bootstrapping process.
Change CommandExchange#publishEvent to not broadcast ExecStatusEvent and
instead check the channelName, this matches what was already done in
CommandExchange#publishEventMessage
Fixes#4293
Ref #4231, #4065
This fixes the regression on sbt 1.2.0 that displays a lot of warnings about configurations.
The warning was added in #4231 in an attempt to fix#4065. This actually highlights somewhat loose usage of configurations among the builds in the wild, and the limitation on the current slash syntax implementation.
I think we can remove this warning for now, and try to fix#4065 by making slash syntax more robust. In particular, we need to memorize the mapping between the configuration name and Scala identifier across the entire build, and use that in the shell.
Ref https://github.com/sbt/sbt/issues/4121
sbt already has the facility to trim stack traces. This sets the trace level of the background run, which fixes the upper half of the `run` stacktrace.

The bottom half requires a similar fix to the foreground log.
