Unify the type of tty_operations::write() counters with the 'count'

This includes changing constants to UL to keep min() and avoid min_t().

This patch appears to cause a warning/error on 32-bit architectures now
due to this part of the change, as size_t is 'unsigned int' there:

Right, this is my brain fart thinking ulong is the same as size_t
everywhere. No, size_t is uint on 32bit.

I will fix this -- kernel build bot seems to be slow -- it didn't find
the issue out in my queue, nor in tty-testing.

'Vote up' my patches to minmax.h that make this all work.
Then it won't care provided both values have the same signedness.
(or, with patch 5, are non-negative 31bit compile time constants.)

Oh yeah, that [1] looks great. Why should one care in min(4096, sizeof()) after all…

So what's the current status of those?
