The src/vol directory on Windows is one of the rare examples
where a single directory builds both lwp and pthreaded versions
of libraries and executables. With this patchset the executables
are fully converted from lwp to pthread. This requires that
afsrpc.dll include the pthread implementations of the threadname,
fasttime, and lock implementations from the LWP directory.
The inclusion within afsrpc.dll permits the dviced and
dvolser directories to avoid rebuilding those object modules.

The code used to start the transmit timer once for every set of packets
that it sends. However, these packets might be sent individually or in
clumps, with blocking for sendmsg, and on peer->lock, between each set
of packet sends. This has the effect of, even on a very stable network,
producing a high degree of variation in RTTs and timeouts. This is a
particular issue where the connection size is larger, as the number of
packets being sent individually under the one timer grows too.
Fix this by moving timer initialisation to SendList. This already takes
the peer lock, so obtain the timeout value here too. This means that
each jumbo gram, or individual packet (where jumbograms are disabled)
is sent with its own start time, and stabilises RTTs.

rxi_Start flagged itself as 'resending' whenever it flushed the
transmit queue due to a resend event. However, it would flush the
entire transmit queue at this point, rather than only transmitting
packets that require a resend. When running with large window sizes
this results an a large number of packets erroneously being marked
as resent.
Instead, let SendXmitList decide whether a packet is being
retransmitted by using the presence of a serial number. This takes
advantage of the fact that a retransmitted packet must be the only
entry in a packet list - we just flag the packet list, instead of
having to maintain counters for each individual packet.

Move the decision about whether a packet contributes to the peer's
rount trip time into the CalculateRoundTripTime function, and improve
the criteria used.
Previously, we only computed the RTT if we had not retransmitted. This
is bad, because it means that places where we have backed off in order
to retransmit never actually lengthen the RTT, and so the RTT is kept
artificially low, and we see a large number of retransmits. Instead,
use the serial of the ACK packet to determine which transmission is
being acknowledged, and if it is the first, or the last, transmission
use the appropriate sent time to calculate the RTT.
If we have no serial in the ACK (for a delayed ack, for example), or
if the serial doesn't match (where a single acknowledgement is soft
acking a number of packets), fall back to only using the ack if the
packet has not be retransmitted.
Also, avoid multiple counting of packets which have arrived as part
of a jumbogram by only permitting the last packet in a jumbogram to
contribute to the RTT. This avoids giving the RTT of jumbograms more
weight than those of normal packets - doing so would pull down the
RTT, as it in effect favours packets which have not be retransmitted.
