Peter Geoghegan a601366a46 Harmonize more parameter names in bulk.
Make sure that function declarations use names that exactly match the
corresponding names from function definitions in optimizer, parser,
utility, libpq, and "commands" code, as well as in remaining library
code.  Do the same for all code related to frontend programs (with the
exception of pg_dump/pg_dumpall related code).

Like other recent commits that cleaned up function parameter names, this
commit was written with help from clang-tidy.  Later commits will handle
ecpg and pg_dump/pg_dumpall.

This directory contains a general purpose data structures, for use anywhere
in the backend:

binaryheap.c - a binary heap

bipartite_match.c - Hopcroft-Karp maximum cardinality algorithm for bipartite graphs

bloomfilter.c - probabilistic, space-efficient set membership testing

dshash.c - concurrent hash tables backed by dynamic shared memory areas

hyperloglog.c - a streaming cardinality estimator

ilist.c - single and double-linked lists

integerset.c - a data structure for holding large set of integers

knapsack.c - knapsack problem solver

pairingheap.c - a pairing heap

rbtree.c - a red-black tree

stringinfo.c - an extensible string type


Aside from the inherent characteristics of the data structures, there are a
few practical differences between the binary heap and the pairing heap. The
binary heap is fully allocated at creation, and cannot be expanded beyond the
allocated size. The pairing heap on the other hand has no inherent maximum
size, but the caller needs to allocate each element being stored in the heap,
while the binary heap works with plain Datums or pointers.

The linked-lists in ilist.c can be embedded directly into other structs, as
opposed to the List interface in nodes/pg_list.h.
