Via ets man page:
Note that for tables of the ordered_set type, safe_fixtable/2 is not
necessary as calls to first/1 and next/2 will always succeed

Preparing to rework the pipelining algorithm

Verified that all code paths using saved table
identifier from state are guarded either by a
check for undefined or a call to maybe_create_ets,
so the table should always be there when it
is needed without creating before real use.

Prior version was "2". New functional tests suite
was not being picked up by local rebar, but was
execute with my local which is version "2.5.2"
which targets the same version of Erlang/OTP
as iBrowse (R16).

For consistency, added macro aliases for remaining
ets table names to be found all in one place.

Reuse of ibrowse_lb for named table holding
load balancers and for name of unnamed table
holding connections was confusing.

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.

Fix failing requests when ibrowse_lb process does not stop gracefully.

Enhanced SOCKS5 Support

Supports HTTP and HTTPS destinations and performs all hostname
resolution via the SOCKS proxy, preventing privacy leakage if used
with Tor.

If hostname is a valid IP address then it is used directly, the
hostname is not resolved again via the SOCKS5 proxy (Patch suggested
by Klaus Trainer but implementation here slightly different).

This reverts commit d8150feeaf.

ibrowse_socks5: fix 'can't find include lib "kernel/src/inet_dns.hrl"'

logic is  wrong in parse_response with the return_raw_request option

if the option return_raw_request` was unset or false, ibrowse was
still returning the returning thhe raw request. This change fix it.

fix send_body pattern matching. Thanks Benoit

fix function_clause error:

        {error,
        {error,
            {'EXIT',
                {{function_clause,
                     [{ibrowse_http_client,do_send_body_1,
                          [{{ok,<<>>},

The case {Function, State} wasn't took in consideration while handling
the body.

Fix silent connection termination - thanks Paul

in that place leads to silent termination, since client will never be
informed. Instead of crashing wait for tcp_closed and cleanup nicely.

Allow missing Content-Length for 303 response.

Run dialyzer by default when compiling. Update travis builds.
