Commit 637f4ca5 637f4ca5d9481742b04b5642e8bd57db1895a9e3 by Alain Magloire
Options

For the new mailbox, one of the short coming with the old stream_t 

	object was that select() was not cover, meaning it was not possible
	to check if a stream was {read,write} ready.  The old was to get
	the fd (stream_get_fd()) and do the select.  Providing,
	stream_is_readready (stream_t, int timeout);
	stream_is_writeready (stream_t, int timeout);
	stream_is_exceptionpending (stream_t, int timeout);
	stream_is_open (stream_t);
	Takes care of it.  It will work specially for tcp stream.

	* mailbox2/stream.c: New functions for the select calls:
	(stream_is_readready): New function.
	(stream_is_writeready): New function.(stream_t, int timeout);
	(stream_is_exceptionpending): New function.
	(stream_is_open): New function.
	* mailbox2/bstream.c (_bs_readline): Bug was truncating the string
	to early.
	(_bs_is_readready): New file.
	(_bs_is_writeready): New file.
	(_bs_is_exceptionpending): New file.
	(_bs_is_open): New file.
	* mailbox2/fstream.c: stubs for the select functions.
	* mailbox2/memstream.c: stubs for the select functions.
	* mailbox2/mapstream.c: stubs for the select functions.
	* mailbox2/tcpstream.c: stubs for the select functions.
	* mailbox2/include/mailutils/stream.h: Adjust the prototypes
	* mailbox2/include/mailutils/sys/stream.h: Adjust the prototypes

	It is better not to put threading (Pthread) code in the low level
	API.  But instead in mailbox_t framework, where it can be control.
	* mailbox2/include/mailutils/pop3.h: Adjust the prototypes.
	* mailbox2/pop3/*.c: Remove threading code.
