[PATCH] consolidate line discipline number definitions

Browse Source 
The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h.  There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure.  The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway.  So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.

Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.
