Run pgindent, pgperltidy, and reformat-dat-files. The pgindent part of this is pretty small, consisting mainly of fixing up self-inflicted formatting damage from patches that hadn't bothered to add their new typedefs to typedefs.list. In order to keep it from making anything worse, I manually added a dozen or so typedefs that appeared in the existing typedefs.list but not in the buildfarm's list. Perhaps we should formalize that, or better find a way to get those typedefs into the automatic list. pgperltidy is as opinionated as always, and reformat-dat-files too.

libpgport
=========
libpgport must have special behavior. It supplies functions to both
libraries and applications. However, there are two complexities:
1) Libraries need to use object files that are compiled with exactly
the same flags as the library. libpgport might not use the same flags,
so it is necessary to recompile the object files for individual
libraries. This is done by removing -lpgport from the link line:
# Need to recompile any libpgport object files
LIBS := $(filter-out -lpgport, $(LIBS))
and adding infrastructure to recompile the object files:
OBJS= execute.o typename.o descriptor.o data.o error.o prepare.o memory.o \
connect.o misc.o path.o exec.o \
$(filter strlcat.o, $(LIBOBJS))
The problem is that there is no testing of which object files need to be
added, but missing functions usually show up when linking user
applications.
2) For applications, we use -lpgport before -lpq, so the static files
from libpgport are linked first. This avoids having applications
dependent on symbols that are _used_ by libpq, but not intended to be
exported by libpq. libpq's libpgport usage changes over time, so such a
dependency is a problem. Windows, Linux, and macOS use an export
list to control the symbols exported by libpq.
