pgsql: Create src/fe_utils/, and move stuff into there from pg_dump's d

Create src/fe_utils/, and move stuff into there from pg_dump's dumputils.

Per discussion, we want to create a static library and put the stuff into
it that until now has been shared across src/bin/ directories by ad-hoc
methods like symlinking a source file.  This commit creates the library and
populates it with a couple of files that contain the widely-useful portions
of pg_dump's dumputils.c file.  dumputils.c survives, because it has some
stuff that didn't seem appropriate for fe_utils, but it's significantly
smaller and is no longer referenced from any other directory.

Follow-on patches will move more stuff into fe_utils.

The Mkvcbuild.pm hacking here is just a best guess; we'll see how the
buildfarm likes it.
