zodbtools provide additional service over zodb (various dumping
routines), but neotools just invokes neo.NewMaster and neo.NewStorage.

For a possible future `neo monitor` maybe bringing neotools back would
be needed, but for now there is simply no reason to keep them around.

not used outside neonet.

Don't try to play with file.readline() - that seems to be working for
usual cases, but:

1. it does not work for cases when e.g. a dot is printed for every test
   run on the same line (e.g. neo/py tests, pytest, etc...)

2. in case when there is a lot of output available ready to be read it
   would be a waste of resources to read/flush it line by line.

-> use raw OS read with sane semantics.

(fix syntax error there)

We now don't buffer anything inside runTestSuite, but the generating
process itself could buffer e.g. stdout. Tell it not to do so.
