Debug logging

[richardschneider]

If debug logging is enabled, via DEBUG environment variable, then all the js-ipfs tests fails. It appears that ipfsd-ctl does not like debug output.

> set DEBUG=*
> aegir test -t node -f test\http-api\interface\block

See the debug.txt

@richardschneider see - #195 (comment)

In esense, if we enable DEBUG=* or DEBUG=ipfs, etc - it will enable the daemon debug output, which will break our stdout/stderr parsing. We can use debugging, but we have to be careful to scope it correctly.

[richardschneider]

With so many processes running in a test, I really need debug logging to figure out why the tests are failing.

ipfsd stdout/stderr parsing SHOULD work with debug logging.

[dryajov]

I'd love to get that working, I just don't see how. Once you enable debugging, it will clog stderr and will have to workaround parsing leggit errors from conflicting log messages.

This should be done with #195
