There are a couple of places in frontend code that could make use of this simple binary heap implementation. This commit makes binaryheap usable in frontend code, much like commit 26aaf97b68 did for StringInfo. Like StringInfo, the header file is left in lib/ to reduce the likelihood of unnecessary breakage. The frontend version of binaryheap exposes a void *-based API since frontend code does not have access to the Datum definitions. This seemed like a better approach than switching all existing uses to void * or making the Datum definitions available to frontend code.
