eal/windows: do not expose private facilities

The goal of rte_os.h is to mitigate OS differences for EAL users.
In Windows EAL, rte_os.h did excessive things:

1. It included platform SDK headers (windows.h, etc). Those files are
   huge, require specific inclusion order, and are generally unused by
   the code including rte_os.h. Declarations from platform SDK may
   break otherwise platform-independent code, e.g. min, max, ERROR.

2. It included pthread.h, which is clearly not always required.

3. It defined functions private to Windows EAL.

Reorganize Windows EAL includes in the following way:

1. Create rte_windows.h to properly import Windows-specific facilities.
   Primary users are bus drivers, tests, and external applications.

2. Remove platform SDK includes from rte_os.h to prevent breaking
   otherwise portable code by including rte_os.h on Windows.
   Copy necessary definitions to avoid including those headers.

3. Remove pthread.h include from rte_os.h.

event/dsw: add port busy cycles xstats

DSW keeps an internal port load estimate, used by the load balancing
mechanism. As a side effect, it keeps track of the total number of
busy cycles since startup. This metric is indirectly exposed in the
form of DSW xstats' "port_<n>_event_proc_latency", which is the total
number of busy cycles divided by the total number of events processed
on a particular port.

An external application can take (event_latency * dequeued) to go back
to busy_cycles. One reason for doing this is to measure the port's
load during a longer time period, without resorting to sampling
"port_<n>_load". However, as the number dequeued events grows, a
rounding error in event_latency renders the application-calculated
busy_cycles inaccurate.

Thus, it makes sense to directly expose the number of busy cycles as a
DSW xstats, even though it might seem redundant.

event/dsw: avoid migration waves in large systems

DSW limits the rate of migrations on a per-port basis. Hence, as the
number of cores grows, so does the total migration capacity.

In high core-count systems, this allows for a situation where flows
are migrated to a lightly loaded port which recently already received
a number of new flows (from other ports). The processing load
generated by these new flows may not yet be reflected in the lightly
loaded port's load estimate. The result is that the previously lightly
loaded port is now overloaded.

This patch adds a rough estimate of the size of the inbound migrations
to a particular port, which can be factored into the migration logic,
avoiding the above problem.
