The parenthesized style has only been used in a few modules. Change
that to use the style that is predominant across the whole tree.

c.h #includes a number of core libc header files, such as <stdio.h>.
There's no point in re-including these after having read postgres.h,
postgres_fe.h, or c.h; so remove code that did so.
While at it, also fix some places that were ignoring our standard pattern
of "include postgres[_fe].h, then system header files, then other Postgres
header files". While there's not any great magic in doing it that way
rather than system headers last, it's silly to have just a few files
deviating from the general pattern. (But I didn't attempt to enforce this
globally, only in files I was touching anyway.)
I'd be the first to say that this is mostly compulsive neatnik-ism,
but over time it might save enough compile cycles to be useful.
The inet/cidr types sometimes failed to reject IPv6 inputs with too many
colon-separated fields, instead translating them to '::/0'. This is the
result of a thinko in the original ISC code that seems to be as yet
unreported elsewhere. Per bug #14198 from Stefan Kaltenbrunner.
Report: <20160616182222.5798.959@wrigleys.postgresql.org>
Regression tests for IPv6 operations added.
Documentation updated to document IPv6 bits.
Stop treating IPv4 as an "unsigned int" and IPv6 as an array of
characters. Instead, always use the array of characters so we
can have one function fits all. This makes bitncmp(), addressOK(),
and several other functions "just work" on both address families.
add family() function which returns integer 4 or 6 for IPv4 or
IPv6. (See examples below) Note that to add this new function
you will need to dump/initdb/reload or find the correct magic
to add the function to the postgresql function catalogs.
IPv4 addresses always sort before IPv6.
On disk we use AF_INET for IPv4, and AF_INET+1 for IPv6 addresses.
This prevents the need for a dump and reload, but lets IPv6 parsing
work on machines without AF_INET6.
To select all IPv4 addresses from a table:
select * from foo where family(addr) = 4 ...
Order by and other bits should all work.

we'll get there one day.
Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.
Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.
