1b852f9959 Various "Fwd" versions of DAG creation functions arn't actually used anywhere! 
Big thanks to Krister for noticing! (Saves another 10K on i386)

e8ffb40a0e Those of us who might be interested in debugging internal memory usage 
of RAIDframe can use RF_DEBUG_MEM.  I suspsect the rest of the world would
rather use that 14K of kernel memory for something else.

a2b9142871 Everyone and their dog was using RF_ERRORMSG3 to print out the same 
sort of error message, over and over again, in different files.
Rather than having the same text repeated in multiple .o files,
create a couple of little functions to do the printing, and save a
bundle of space.  Also improves readability of code.

77a6b82b27 Merge the gehenna-devsw branch into the trunk. 
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

2a80a0fbe1 make 'configureMutex' be a lockmgr lock instead of a simple lock.

813fbd6152 RF_LOCK_MUTEX()/RF_UNLOCK_MUTEX() often cover more code than they 
needs to.  In particular, they often surround calls to malloc().
Re-work the locking on most macros to avoid this problem.

XXX: On MP systems, simultaneous calls to the GET macros when a
freelist is empty may cause that freelist to grow more quickly than
before.  Given that the "increment" value of these lists are fairly
small, this shouldn't be too much of an issue.
