This updates CONTRIBUTING to reflect the changes to use the
master branch and make explicit recommendations about updating
CHANGELOG.md and providing test coverage. Also, this includes
some old updates to PROJECTS.md that I wrote to expand the list
of projects, pulling in things from old feature requests.
* Make GIT_INLINE an internal definition so it cannot be used in
public headers
* Fix language in CONTRIBUTING
* Make index caps API use signed instead of unsigned values
The discussion about converting some of our foreach-style APIs to
use iterator objects got me wanting to make a list of good starter
projects. I put it in CONTRIBUTING.md and then went crazy with
updates to that file and to CONVENTIONS.md.
