Bruce Evans e2f03b0df0 Speed up ttnread() in the !(ICANON | ISIG) case by copying to user space ...

through a temporary buffer instead of one character at a time.  The old
method takes about 6 usec/char on a 486DX2/66.  This is larger than than
the combined interrupt and PIO overhead for a 16550!

This change was first implemented in 1.1.5.  It was rewritten for 2.1.
The clist access functions allow a simpler implementation at some cost
in correctness and speed.  There needs to be an ungetc() function to
recover from EFAULT, and it wastes time to copy through a temporary
buffer.

Don't snoop on single characters that weren't read due to EFAULT.
Rewrite a snoop comment in my approximation to English.

Undo bogus exportation of ttnread().
