Initial client API
updating test_client.c
Added sample chunk callbacks for client
Updating test_client.c
Added function evhtp_unbind_socket

evhtp_unbind_socket stops listen socket, and deallocs all memomry
allocated by evhtp_new.

Valgrind with code:
int
main(int argc, char ** argv) {
    evbase_t * evbase = event_base_new();
    evhtp_t  * htp    = evhtp_new(evbase, NULL);
    evhtp_callback_t * cb;

    cb = evhtp_set_cb(htp, "/test", testcb, NULL);
    evhtp_callback_free(cb);
    evhtp_bind_socket(htp, "0.0.0.0", 8080, 1024);

    return 0;
}

Merge from master fixups
Add test_proxy: example code for using evhtp_client functionality to implement an HTTP reverse proxy.
Add evhtp_kvs_add_kvs / evhtp_headers_add_headers to copy headers from source to dest.
Update test_proxy: pause the frontend request while processing the backend request; pass headers through with evhtp_headers_add_headers; run backend requests on same thread evbase as the related frontend request.
Merge pull request #38 from jbro/master

Accept requests like <method> <protocol>://<host> <http version>
That is, without an extra / after the host. Consider the path as /
and keep parsing the line instead of reverting to HTTP 0.9
Drain before letting ownership change.
