printk wrapper macros - first shot
Add a number of printk-like macros to print messages for span and
channel. I found them useful in the sysfs branch.
The _dbg ones use the magical variable debug, and hence require the code
to acknowledge that explicitly by defining DAHDI_PRINK_MACROS_USE_debug
explicitly.
