Add run time control for receive DMA buffer fill level to allow application to control receive latency when using stream oriented serial protocols that pass receive data to application only after a DMA buffer fills. This was previously a compile time option, but run time control is needed when application changes data rate (and latency requirements) or uses different data rates on different ports.

Improve the accuracy of TIOCOUTQ value as implemented in chars_in_buffer() method by walking and counting tx DMA buffers, reading controller tx FIFO level and accounting for controller tx shift register.

Fix the epca driver to call epca_setup() if digiepca=xxx is included on the command line and the epca driver is built in. epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere along the way that call was removed but not replaced.

Fix the Stallion driver's putchar() and break_ctl() ops and iStallion's putchar() to return values. Is it actually possible for putchar() or break_ctl() to be called with tty == NULL or can the check be discarded? Should stl_write() be returning 0 if tty->driver_data is NULL or tx.buf is NULL? Is this even possible? I've made Stallion's functions return -EINVAL as stli_breakctl() if the checks fail.

Every tty driver has its own concept of a port structure and because they all differ we cannot extract commonality. Begin fixing this by creating a structure drivers can elect to use so that over time we can push fields into this and create commonality and then introduce common methods.
