* src/w32-estream.c (reader): Use standard free.
(writer): Ditto.
--
There are two errors: The minor one is that we allocated with calloc
but released with _gpgrt_free. The major one is the recursive use of
npth_unprotect due to the syscall_clamp mechanism:
1. Around the call to _gpgrt_w32_poll
2. By gpgrt_lock_lock on behalf of a the custom allocation handler in
the worker threads at their _gpgrt_free.
This problem was exhibited by GnuPG's dirmngr component.

* src/gpgrt-int.h (trace_errno): Add new parameter. Adjust all users.
* src/init.c (trace_fp, trace_with_errno, trace_missing_lf)
(trace_prefix_done): New vars.
(_gpgrt_internal_trace_begin): Add arg WITH_ERRNO. Open a trace file
on first use. Init new vars.
(print_internal_trace_prefix): New.
* src/estream.c, src/w32-estream.c: Improve tracing.

* src/w32-estream.c: Replace existing trace calls by the new
framework.

* src/w32-estream.c (TRACE_ERR): Also print the error number. This is
in particular useful on non-english systems.
(reader_context_s, writer_context_s): Replace the gpgrt mutex by a
native critical section. Change all calls to gpgrt_lock_ fucntions by
the EnterCriticalSection et al.
(_gpgrt_w32_poll): Make CODE unsigned which is what WFMO returns.
Remove the then useless condition.

The locking code here is self-contained and may badly interact with
the possible nPth "clamped" gpgrt lock functions.

* src/Makefile.am (arch_sources): Add new file.
* src/estream.c (O_NONBLOCK): Move to 'gpgrt-int.h'.
(BUFFER_BLOCK_SIZE): Likewise.
(BUFFER_UNREAD_SIZE): Likewise.
(struct notify_list_s, notify_list_t): Likewise.
(struct _gpgrt_stream_internal, estream_internal_t): Likewise.
(X_POLLABLE): New macro.
(parse_mode): Parse keyword 'pollable', emulate O_NONBLOCK using the
same mechanism on Windows.
(_gpgrt_poll): Use the new '_gpgrt_w32_poll' on Windows.
* src/gpgrt-int.h (_gpgrt_functions_w32_pollable): New declaration.
(_gpgrt_w32_pollable_create): New prototype.
(_gpgrt_w32_poll): Likewise.
* src/w32-estream.c: New file. This code is adapted from GPGME.
* tests/t-poll.c (create_pipe): Create pollable streams.
