dialyzer no_spec warnings

[norton]

There are several R15B02 dialyzer warnings reported for the ibrowse_test_server module when using the "--no_spec" option. These may or may not be critical. Nevertheless, I find it helpful to dialyze test code as well.

ibrowse_test_server.erl:73: The call ssl:controlling_process(Sock::port(),Pid::pid()) will never return since the success typing is ({'sslsocket',_,pid()},pid()) -> 'ok' | {'error',_} and the contract is (#sslsocket{},pid()) -> 'ok' | {'error',reason()}
ibrowse_test_server.erl:78: The call ssl:setopts(Sock::port(),Opts::any()) will never return since the success typing is ({'sslsocket',_,_},any()) -> 'ok' | {'error',_} and the contract is (#sslsocket{},[gen_tcp:option()]) -> 'ok' | {'error',reason()}
ibrowse_test_server.erl:170: The call ssl:send(Sock::port(),Resp::<<_:64,_:_*8>> | [<<_:136,_:_*104>> | [any(),...],...]) will never return since the success typing is ({'sslsocket',_,pid()},binary() | maybe_improper_list(binary() | maybe_improper_list(any(),binary() | []) | byte(),binary() | [])) -> 'ok' | {'error',_} and the contract is (#sslsocket{},iodata()) -> 'ok' | {'error',reason()}
ibrowse_test_server.erl:177: Clause guard cannot succeed. The pattern <Body, _ChunkSize> was matched against the type <string(),50>
ibrowse_test_server.erl:186: Guard test is_binary(Body::string()) can never succeed
