* gpgcedev.c (GPGCEDEV_IOCTL_ASSIGN_RVID): New call ASSIGN_RVID.
        (PIPE_FLAG_HALT_MONITOR): New flag.
        (struct pipeimpl_s): New members monitor_proc, monitor_access.
        (pipeimpl_new): Initialize them.
        (assert_pipeimpl): New function.
        (access_opnctx, make_pipe): Use it.
        (make_pipe): If there is a monitor, halt it.
        (monitor, assign_rvid): New functions.
	(GPG_IOControl): Handle GPGCEDEV_IOCTL_ASSIGN_RVID.

	* gpgcedev.c: Use index (between 1 and table size) into
	opnctx_table as public context identifiers, instead using pointers
	into the table directly (which are not stable under table resize).
	(OPNCTX_TO_IDX, OPNCTX_FROM_IDX, OPNCTX_VALID_IDX_P): New macros.

	* assuan-handler.c (std_handler_input,
	std_handler_output) [HAVE_W32CE_SYSTEM]: Finish the pipe.  We must
	do this here, because otherwise assuan_close_input_fd() and
	assuan_close_output_fd() can't work.
	* system-w32ce.c (_assuan_w32ce_finish_pipe): Call SetLastError in
	error case.
	(__assuan_close): Save WSAGetLastError before trashing it!
	Otherwise handle is never closed and GPGME hangs.

	* w32ce-add.h (ASSUAN_STDIN, ASSUAN_STDOUT): Define magic handle values.
	* system-w32ce.c (__assuan_read, __assuan_write): Handle magic
	handle values differently.
	
	* system-w32ce.c (_assuan_w32ce_finish_pipe): Return error on RVID 0.

	* gpgcedev.c (GPGCEDEV_IOCTL_UNBLOCK): New ioctl.
	(PIPE_FLAG_UNBLOCK_READER, PIPE_FLAG_UNBLOCK_WRITER): New flags.
	(GPG_Read): Check if PIPE_FLAG_UNBLOCK_READER is set and return
	ERROR_BUSY in that case.
	(GPG_Write): Likewise for PIPE_FLAG_UNBLOCK_WRITER.
	(unblock_call): New function.
	(GPG_IOControl): Implement GPGCEDEV_IOCTL_UNBLOCK.

	* gpgcedev.c: This rewrite does away with troublesome race
	conditions (close vs everything else, for example) by simplifying
	the locking model.  It also handles EOF, EPIPE, but still assumes
	that there is always only ever one reader and writer.  Also, no
	need to treat ERROR_PIPE_NOT_CONNECTED and ERROR_BUSY as EAGAIN
	anymore.
	(struct pipeimpl_s, pipeimpl_t): New types.
	(PIPE_FLAG_NO_READER, PIPE_FLAG, NO_WRITER): New macros.
	(struct opnctx_s): Remove everything that's now in struct
	pipeimpl_s.  Remove also assoc and locked.  Add pipeimpl field.
	(pipeimpl_new, pipeimpl_unref, allocate_opnctx, verify_opnctx,
	access_opnctx): New functions.
	(get_new_opnctx, find_and_lock_opnctx, validate_and_lock_opnctx,
	unlock_opnctx): Removed.
	(GPG_Init, GPG_Deinit): Improve debugging output.
	(GPG_Open): Improve debugging output, use allocate_opnctx instead
	of get_new_opnctx.
	(GPG_Close): Improve debugging output.  Rewrite to use reference
	counting.  Also check if reader or writer is closed and set flags
	for triggering EOF or EPIPE.
	(GPG_Read): Improve debugging output.  Rewrite using pipeimpl.
	Check for EOF.
	(GPG_Write): Improve debugging output.  Rewrite using pipeimpl.
	Check for EPIPE.
	(make_pipe): Rewrite using pipeimpl.
	(GPG_IOControl): Improve debugging output.

	* assuan-uds.c (uds_reader, uds_sendfd): Don't break strict
	aliasing rules.

	* Makefile.am (EXTRA_DIST): Add gpgcedev.def.

fixed a problem for W32CE and Pth.

Reorganized the source.

	* libassuan.vers, libassuan.def: Add assuan_set_sock_nonce.

Implement getenv replacement for W32CE.

	* configure.ac (_DARWIN_C_SOURCE): Define on frapple.

	* debug.h (TRACE_LOG5): Add macro.
	* debug.c (_assuan_debug_buffer): Add newline
	* system.c: Add more debug output (conditioned on the compile-time
	DEBUG_SYSIO macro).
