Fix some oversights in BRIN patch. Remove HeapScanDescData.rs_initblock, which wasn't being used for anything in the final version of the patch.
Fix IndexBuildHeapScan so that it supports syncscan again; the patch broke synchronous scanning for index builds by forcing rs_startblk to zero even when the caller did not care about that and had asked for syncscan. Add some commentary and usage defenses to heap_setscanlimits(). Fix heapam so that asking for rs_numblocks == 0 does what you would reasonably expect. As coded it amounted to requesting a whole-table scan, because those "--x <= 0" tests on an unsigned variable would behave surprisingly.
