test proxy supports CONNECT

There's a new 'http-proxy' server for tests that runs on a separate port
and lets clients do HTTP CONNECT to other ports on the same host to
allow us to test HTTP "tunneling" properly.

Test cases now have a <proxy> section in <verify> to check that the
proxy protocol part matches correctly.

Test case 80, 83, 95, 275, 503 and 1078 have been converted. Test 1316
was added.

sws.c: HTTP and GOPHER test server-side connection closing adjustment

When, for a given test, server is instructed to close connection after
server reply we now wait a very small amount

sws.c: HTTP and GOPHER test server-side connection closing adjustment

When, for a given test, server is instructed to close connection after
server reply we now wait a very small amount of time (50ms) before doing
so. This is done to allow client to, at least partially, read server
reply before getting an ECONNRESET.

The above is required to make test cases 1070, 1200, 1201 and 1202 pass
with Cygwin 1.5.X on W2K.

GOPHER test server closes connection after _every_ server-reply, as such,
at some point it could require a bigger time or using shutdown() before
a server-side initiated disconnection.

sws: added basic gopher support

remove the CVSish $Id$ lines

convert Curl_ultous() and Curl_ultouc() functions to curlx_ultous() and
curlx_ultouc(), exposing them through curlx.h to allow proper code reuse
later in our test harness.
