items that don't have specific values in the board's defconfig file.

If this rule is not followed, then introducing a new Kconfig can produce
a loop like this:

   Break things (BREAK_ME) [] (NEW)
   Error in reading or end of file.

   Break things (BREAK_ME) [] (NEW)
   Error in reading or end of file.

The continues forever since buildman passes /dev/null to 'conf', and
the build system just tries again. Eventually there is so much output that
buildman runs out of memory.

We can detect this situation by looking for a symbol (like 'BREAK_ME')
which has no default (the '[]' above) and is marked as new. If this
appears multiple times in the output, we know something is wrong.

Add a filter function for the output which detects this situation. Allow
it to return True to terminate the process. Implement this termination in
cros_subprocess.
