preprocessor conditional blocks.

I picked the value from the error message:

platforms. Bug seen on 64-bit Linux when using "make profile-opt".

Only align the "frame_t" structure on 32-bit when Visual Studio is used. Before
the alignment to 32-bit was applied to the whole file any compiler supporting
"#pragma pack(4)" which includes GCC.

Improve also the "Logging" section

Use the granularity to check the minimum time delta, instead of arbitrary
value.

Use the same default timeout than Makefile: 1 hour (3600 seconds).

Windows) instead of using the "duplex" pipe transport. The new class uses a
simpler overlapped read to be notified when the pipe is closed. So the protocol
doesn't need to implement eof_received(): connection_lost() is called instead.
_UnixWritePipeTransport has the same approach.

instead of rounding towards zero, in select and selectors modules:
select.epoll.poll(), selectors.PollSelector.poll() and
selectors.EpollSelector.poll(). For example, a timeout of one microsecond
(1e-6) is now rounded to one millisecondi (1e-3), instead of being rounded to
zero.

Mention the change in Misc/NEWS.

Improve also debug info to analyze the issue

Add also event more debug info
