These two close operations were added to work around #1708, but caused #2675.
We found the root cause of the hanging problem in #1708 is a race
condition when creating Windows processes:
When Bazel trys to create two processes, one for a local command
execution, one for starting the worker process. The worker process
might accidentally inherits handles opened when creating the local
command process, and it holds those handles as long as it lives.
Therefore, ReadFile function hangs when handles for the write end of
stdout/stderr pipes are released by the worker.
The solution is to make Bazel native createProcess JNI function
explicitly inheirts handles as needed, and use this function to start
worker process.

This should help users and developers a lot figuring out *why* the worker crashed as the log file was very undiscoverable for them.
Part of the "make error messages great" effort (#2855).

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.

I know this should have been split up, but I was a bit on fire today and did it all in one go ^^;
Fixes spurious "Stream closed: Stream closed" errors, by noticing dead workers and retrying with a fresh one. (Configurable with the --worker_max_retries flag.)
Fixes an "IllegalArgumentException" when a non-worker compatible Spawn is given to the strategy. We fall back to StandaloneSpawnStrategy now.
Redirect the stderr of worker processes to separate log files in a common sub-directory and print a message that tells you about the location on worker start-up for easier debugging. The log can be found in <output_base>/worker-logs/*.log.
Adds the mnemonic of the Spawn to log messages and the log filename.
Adds verbose messages on worker start-up and shutdown. (Enable it with --worker_verbose!)
Shuts down the worker pool after a build finished by default, until we sort out one last remaining correctness issue. This also conserves resources, though makes incremental builds a bit slower. Want the maximum performance anyway? Try --experimental_workers_keep_running.
Adds stack traces to errors that are caused by buggy workers to aid development.
Fixes weird dupli..tripli..quadruple error messages ("Compiling failed: Stream closed: Stream closed: Stream closed: Stream closed.").

This will be used by the persistent JavaBuilder, which improves performance of Java compilation by 4x due to profiting from JVM JIT optimizations and not having to relaunch the JVM for every spawn.
It is completely generic though, so as long as a tool (ProGuard? Dexer? Whatever.) conforms to the Worker process protocol, it can use the new spawn strategy.
