* src/w32-io.c (set_synchronize): Remove.
(create_reader, create_writer): No need for set_synchronize.
--
The set_synchronize dates back to 2001 at a time when gpgme got
the Windows support on WindowsME and Windows2000. Maybe this was
required then due to bugs in that old NT or partly NT based Windows
versions.
Removal similar to the removal in gpgme's w32-io.

* 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/estream.c: Add trace calls to some functions.
* 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.
