	serial driver working and robust.  At this point it works quite well,
	using the default buffer sizes.  Changing from the defaults seem to
	easily break it though, certainly on input.  Also, changing the baud
	rate seems to not work reliably.

	* src/common/serial.c: Add some tracing/debug info to try and debug
	problems with QUICC serial driver.  These are hard disabled with
	"XX_" prepended to "CYGDBG_DIAG_BUF".  Enabling them gives information
	about how/when data are delivered from the serial driver.

	* include/pkgconf/io_serial.h: Adjust limits and defaults on number and
	size of buffers with values that seem to work.

	* src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit
	to avoid compiler warnings.

	is now always enabled, just the interrupts are masked/unmasked to control it.
	This lets the serial driver cooperate with Cygmon on the port used for GDB.
	Note that currently serial input does not work for CON1 since Cygmon is
	taking all of the receive interrupts for itself.
