Document what key projects use shapelib

[schwehr]

Thanks to @dbaston for pointing out that there are places other than gdal that shapelib is included.

And specifically:

• Which parts of shapelib?
• What is the best link for each?
• Do they add anything?

Packages

• gdal/ogr/ogrsf_frmts/shape
• postgis/loader pgsql2shp and shp2pgsql

Package maintainers (only include if they directly package part of shapelib).

• Debian/Ubuntu - Adds man pages
• Fedora
• FreshPorts - FreeBSD
• CondaForge
• NetBSD pkgsrc

please add to Package maintainers (or a new section named 'Distributions'): MS4W (also includes contrib utilities for Windows users)

The "foreign" package, which is distributed with base R (the language), uses the shapelib DBF reader. Their SVN repo is https://svn.r-project.org/R-packages/trunk/foreign/src/ , mirrored to GitHub at https://github.com/cran/foreign

@dbaston , I just found https://github.com/fulcrumapp/shp-ruby/tree/master/ext/shp that treats all the shapefil source as c++, which appears to be different that what you found with cran.

Please add GRASS GIS, https://github.com/OSGeo/grass/tree/master/lib/external/shapelib/
Mainly OGR is used, yet this older copy is still included.

Where should the resulting list go?

Should there be something like doc/users.md in the resulting tar? Or maybe just a wiki page on github? I definitely don't think this issue should be the final location of this list.

I see https://pypi.org/project/pyshapelib/ I am just on a phone at the moment, so I can't look into the zip at the moment. If this code it decent, maybe it's worth bring it to github and making sure it's in decent shape. I can't even see it's license. Is it using the shapelib c code? How does it interface with the C if so. And probably no tests.
