Subject: [PATCH] pass extra file to child process as status handler

instead of using stdout/stderr as the status handler, we pass an extra file to
the child process and write `0\n` or `1\nerror message` to it and close it
after. This allow the child process to handle stdout/stderr as normal.

Builder v2

Current approach

Right now, the builder is very tightly coupled with docker core. The builder has the following roles:

• process the build context
• parse Dockerfile into sexp-expressions
• evaluate individual sexp-expressions which may involves the following job:
• persist configurations i.e ENV, EXPOSE, VOLUME, etc.
