In preparation for work to ensure that request
load is balanced across connections, created failing
functional test to demonstrate current behavior.

New endpoint will never send back a response and can
be used for verifying timeouts and long running processes.

New eunit based test harness for functional
tests that require a running test server in
order to run.

Moved receive of stop message to listening process
instead of connection and modified listener to come
up for air every once in a while to process.

Move src/ibrowse_test.erl file to the test directory.
