Increase upper bound for bgwriter_lru_maxpages.

Browse Source 
There is no particularly good reason to limit this value to 1000,
so increase the limit to INT_MAX / 2, the same limit we use for
shared_buffers.  It's not clear how much practical effect larger
settings will have, but there seems no harm in letting people try it.

Jim Nasby, less a comment change I stripped out.
