Log message:
uniq(1): support arbitrarily long input lines
Switch from fgets(3) to getline(3) to support input lines of any
length.
Tested by sthen@, who uncovered a dumb bug that cut throughput in
half. getline(3) is indeed slower than fgets(3), but not *twice* as
slow.
millert@ suggests that preallocating both line buffers might be
worthwhile. I will need to do some additional testing to figure out
whether 8KB buffers (like we had for fgets(3)) are appropriate
starting lengths. For now I am not preallocating either buffer.
ok millert@ sthen@
