The test had been setting an arbitrary 200ms timeout to allow the
server's handler to set up before timing out. That is not only
potentially flaky on slow machines, but also typically much longer
than necessary. Replace the hard-coded timeout with a much shorter
initial timeout, and use exponential backoff to lengthen it if needed.
This allows the test to be run about 20x faster in the typical case,
which may make it easier to reproduce rare failure modes by running
with a higher -count flag.

This is one step towards optimizing WriteMsgUDPAddrPort.
Further steps remain, namely to avoid the syscall.Sockaddr interface,
as we do for UDPConn.WriteToUDP and UDPConn.ReadFromUDP.
A previous change optimized ReadMsgUDPAddrPort by having
ReadMsgUDP call ReadMsgUDPAddrPort rather than the other way around.
This change does not implement WriteMsgUDP in terms of WriteMsgUDPAddrPort,
because a few layers deep, on posix platforms only
(in ipToSockaddrInet4 and ipToSockaddrInet6),
is special handling of zero-length IP addresses and IPv4zero.
It treats IP(nil) as equivalent to 0.0.0.0 or ::,
and 0.0.0.0 as equivalent to :: in an IPv6 context.
Based on the comments, I suspect that this treatment was intended
for the Listen* API, not the Write* API, but it affects both,
and I am nervous about changing the behavior for Write*.
The netip package doesn't have a way to represent a "zero-length IP address"
as distinct from an invalid IP address (which is a good thing),
so to implement WriteMsgUDP using WriteMsgUDPAddrPort,
we would have to duplicate this special handling at the start of WriteMsgUDP.
But this handling depends on whether the UDPConn is an IPv4 or an IPv6 conn,
which is also platform-specific information.
As a result, every attempt I made to implement WriteMsgUDP using
WriteMsgUDPAddrPort while preserving behavior ended up
being considerably worse than copy/paste/modify.
This does mean that WriteMsgUDP and WriteMsgUDPAddrPort will have
different behavior in these cases.

Instead of implementing ReadMsgUDPAddrPort in terms of ReadMsgUDP,
do it the other way around. This keeps the code minimal while
still avoiding allocs.
We could also rearrange ReadMsgUDP to be mid-stack inlined to avoid
allocating the *UDPAddr, but anyone who's trying to eliminate
allocs should use ReadMsgUDPAddrPort instead anyway,
because ReadMsgUDP will always allocate at least once (the IP slice).

The net/http package has a documented contract that if DialContext, DialDLSContext, Dial or DialTLS are specified in an instance of Transport, that they will be used to set up the connection. If they are not specified, then a reasonable fallback is made (e.g. using the net package).
This is ordinarily true, except for when compiling for the js/wasm target, where the browser's Fetch API is preferred in all cases (except for when it is undefined/unavailable) and therefore the dial functions are all ignored. As a result, the http.Transport implementation under js/wasm doesn't meet that contract.
This PR updates the RoundTrip behaviour of http.Transport so that if DialContext, DialTLSContext, Dial or DialTLS are specified, they are used as expected. The Fetch API will be used as a fallback if they are not specified.

The docs say:
If the input is at EOF, Decode returns io.EOF and does not modify e.
However, the added test fails:
--- FAIL: TestDecodePartial (0.00s)
encoder_test.go:1263: 31/81: expected io.ErrUnexpectedEOF: EOF
encoder_test.go:1263: 51/81: expected io.ErrUnexpectedEOF: EOF
In particular, the decoder would return io.EOF after reading a valid
message for a type specification, and then hit EOF before reading a data
item message.
Fix that by only allowing a Decode call to return io.EOF if the reader
hits EOF immediately, without successfully reading any message.
Otherwise, hitting EOF is an ErrUnexpectedEOF, like in other cases.
Also fix a net/rpc test that, coincidentally, expected an io.EOF
as an error when feeding bad non-zero data to a gob decoder.
An io.ErrUnexpectedEOF is clearly better in that scenario.
