Your proposal may make sense for your particular project, but there is no
specific standard.
You should split your headers whichever way makes the most sense for your
project's API. Arbitrary rules like one header per source file do not get
you much (unless your code is already hopelessly disorganized).
Package-specific headers should probably installed using pkginclude_HEADERS,
which will default to /usr/local/include/PACKAGE/. This may include things
like primary interface headers (data types and function protocols) as well
as any internal headers needed for special purposes (modules, extensions,
etc.).
Artificially reducing the number of #includes is probably not worthwhile. If
it makes sense to break your public interface into several headers, go for
it. An example might be if your library has a standard or simple
interface, and an additional advanced interface that allows finer-grain
interaction. Another may be if your library has multiple uses, and it is
conceivable a developer may wish to use one portion but not the rest.
(So, don't split by source file, but do split by component or task.)
