Convert GNU make to use the gnulib portability library

Move content from glob/* and config/* into standard GNU directory
locations lib/* and m4/*.

Install the gnulib bootstrap script and its configuration file, and
create a bootstrap.bat file for Windows.  Update the README.git file
with new requirements and instructions for building from Git.

At this point we only install the alloca, getloadavg, and FDL modules
from gnulib.  We keep our old glob/fnmatch implementation since the
gnulib versions require significant amounts of infrastructure which
doesn't exist on Windows yet.  Further work is required here.

Due to a problem with gnulib's version of getloadavg, we need to bump
the minimum required version of automake to 1.16.1 unfortunately.
