as determined by include-what-you-use (IWYU)
While IWYU also suggests to *add* a bunch of #include's (which is its
main purpose), this patch does not do that. In some cases, a more
specific #include replaces another less specific one.
Some manual adjustments of the automatic result:
- IWYU currently doesn't know about includes that provide global
variable declarations (like -Wmissing-variable-declarations), so
those includes are being kept manually.
- All includes for port(ability) headers are being kept for now, to
play it safe.
- No changes of catalog/pg_foo.h to catalog/pg_foo_d.h, to keep the
patch from exploding in size.
Note that this patch touches just *.c files, so nothing declared in
header files changes in hidden ways.
As a small example, in src/backend/access/transam/rmgr.c, some IWYU
pragma annotations are added to handle a special case there.

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.

In a similar effort to f01592f91, here we're targetting fixing the
warnings where we've deemed the shadowing variable to serve a close enough
purpose to the shadowed variable just to reuse the shadowed version and
not declare the shadowing variable at all.
By my count, this takes the warning count from 106 down to 71.

There were a number of issues in the recent commits which include typos,
code and comments mismatch, leftover function declarations. Fix them.

Switch to 2.1 version of pg_bsd_indent. This formats
multiline function declarations "correctly", that is with
additional lines of parameter declarations indented to match
where the first line's left parenthesis is.

Mostly cosmetic adjustments, but I added a more reliable method of
detecting whether an iteration is in progress.

Coverity complained that simple8b_encode() might read beyond the end of
the 'diffs' array, in the loop to encode the integers. That was a false
positive, because we never get into the loop in modes 0 or 1, and the
array is large enough for all the other modes. But I admit it's very
subtle, so it's not surprising that Coverity didn't see it, and it's not
very obvious to humans either. Refactor it, so that the second loop
re-computes the differences, instead of carrying them over from the first
loop in the 'diffs' array. This way, the 'diffs' array is not needed
anymore. It makes no measurable difference in performance, and seems more
straightforward this way.
Also, improve the comments in simple8b_encode(): fix the comment about its
return value that was flat-out wrong, and explain the condition when it
returns EMPTY_CODEWORD better.
In the passing, move the 'selector' from the codeword's low bits to the
high bits. It doesn't matter much, but looking at the original paper, and
googling around for other Simple-8b implementations, that's how it's
usually done.
Per Coverity, and Tom Lane's report off-list.

There were more large constants that needed UINT64CONST. And one variable
was declared as "int", when it needed to be uint64. These bugs were only
visible on 32-bit systems; clearly I should've tested on one, given that
this code does a lot of work with 64-bit integers.
Also, in the test "huge distances" test, the code created some values with
random distances between them, but the test logic didn't take into account
the possibility that the random distance was exactly 1. That never actually
happens with the seed we're using, but let's be tidy.

The set is implemented as a B-tree, with a compact representation at leaf
items, using Simple-8b algorithm, so that clusters of nearby values use
less memory.
The IntegerSet isn't used for anything yet, aside from the test code, but
we have two patches in the works that would benefit from this: A patch to
allow GiST vacuum to delete empty pages, and a patch to reduce heap
VACUUM's memory usage, by storing the list of dead TIDs more efficiently
and lifting the 1 GB limit on its size.
This includes a unit test module, in src/test/modules/test_integerset.
It can be used to verify correctness, as a regression test, but if you run
it manully, it can also print memory usage and execution time of some of
the tests.
