	* tls.c (ImportObjCmd): removed unnecessary use of 'bio' arg.
	(Tls_Init): check return value of SSL_library_init.  Also lots of
	whitespace cleanup (more like Tcl Eng style guide), but not all
	code was cleaned up.

	* tlsBIO.c: minor whitespace cleanup

	* tlsIO.c: minor whitespace cleanup.
	(TlsInputProc, TlsOutputProc): Added ERR_clear_error before calls
	to BIO_read or BIO_write, because we could otherwise end up
	pulling an error off the stack that didn't belong to us.  Also
	cleanup up excessive use of gotos.
