We used to strategically place newlines after some function call left
parentheses to make pgindent move the argument list a few chars to the
left, so that the whole line would fit under 80 chars. However,
pgindent no longer does that, so the newlines just made the code
vertically longer for no reason. Remove those newlines, and reflow some
of those lines for some extra naturality.

By project convention, these names should include "P" when dealing with a
pointer type; that is, if the result of a GETARG macro is of type FOO *,
it should be called PG_GETARG_FOO_P not just PG_GETARG_FOO. Some newer
types such as JSONB and ranges had not followed the convention, and a
number of contrib modules hadn't gotten that memo either. Rename the
offending macros to improve consistency.
In passing, fix a few places that thought PG_DETOAST_DATUM() returns
a Datum; it does not, it returns "struct varlena *". Applying
DatumGetPointer to that happens not to cause any bad effects today,
but it's formally wrong. Also, adjust an ltree macro that was designed
without any thought for what pgindent would do with it.
This is all cosmetic and shouldn't have any impact on generated code.

Don't move parenthesized lines to the left, even if that means they
flow past the right margin.
By default, BSD indent lines up statement continuation lines that are
within parentheses so that they start just to the right of the preceding
left parenthesis. However, traditionally, if that resulted in the
continuation line extending to the right of the desired right margin,
then indent would push it left just far enough to not overrun the margin,
if it could do so without making the continuation line start to the left of
the current statement indent. That makes for a weird mix of indentations
unless one has been completely rigid about never violating the 80-column
limit.
This behavior has been pretty universally panned by Postgres developers.
Hence, disable it with indent's new -lpl switch, so that parenthesized
lines are always lined up with the preceding left paren.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains
prototypes for all functions registered in pg_proc.h. This avoids
having to manually maintain these prototypes across a random variety of
header files. It also automatically enforces a correct function
signature, and since there are warnings about missing prototypes, it
will detect functions that are defined but not registered in
pg_proc.h (or otherwise used).

For upcoming BRIN opclasses, it's convenient to have strategy numbers
defined in a single place. Since there's nothing appropriate, create
it. The StrategyNumber typedef now lives there, as well as existing
strategy numbers for B-trees (from skey.h) and R-tree-and-friends (from
gist.h). skey.h is forced to include stratnum.h because of the
StrategyNumber typedef, but gist.h is not; extensions that currently
rely on gist.h for rtree strategy numbers might need to add a new
A few .c files can stop including skey.h and/or gist.h, which is a nice
side benefit.

(It's not clear to me why bootscanner.l has any #include lines at all.)
The consistent function contained several bugs:
* The "if (which2) { ... }" block was broken. It compared the argument's
lower bound against centroid's upper bound, while it was supposed to compare
the argument's upper bound against the centroid's lower bound (the comment
was correct, code was wrong). Also, it cleared bits in the "which1"
variable, while it was supposed to clear bits in "which2".
* If the argument's upper bound was equal to the centroid's lower bound, we
descended to both halves (= all quadrants). That's unnecessary, searching
the right quadrants is sufficient. This didn't lead to incorrect query
results, but was clearly wrong, and slowed down queries unnecessarily.
* In the case that argument's lower bound is adjacent to the centroid's
upper bound, we also don't need to visit all quadrants. Per similar
reasoning as previous point.
* The code where we compare the previous centroid with the current centroid
should match the code where we compare the current centroid with the
argument. The point of that code is to redo the calculation done in the
previous level, to see if we were supposed to traverse left or right (or up
or down), and if we actually did. If we moved in the different direction,
then we know there are no matches for bound.
Refactor the code and adds comments to make it more readable and easier to
reason about.
Backpatch to 9.3 where SP-GiST support for range types was introduced.
The implementation is a quad-tree, largely copied from the quad-tree
implementation for points. The lower and upper bound of ranges are the 2d
coordinates, with some extra code to handle empty ranges.
I left out the support for adjacent operator, -|-, from the original patch.
Not because there was necessarily anything wrong with it, but it was more
complicated than the other operators, and I only have limited time for
reviewing. That will follow as a separate patch.
