There is a problem with dependency order when installing packages. The key
problem revolves around the satisfy_dependencies_for() function which is
called from opkg_install_pkg just before the installation (and preinst)
happens.
The satisfy_dependencies_for() function calls pkg_hash_fetch_unsatisfied_dependencies()
which will only return packages which were previously not marked as
*going* to be installed at some point. For the purposes of
opkg_install_pkg() we really need to know which dependencies haven't been
installed yet.
This patch adds pkg_hash_fetch_satisfied_dependencies() which returns a
list of package dependencies. We can then directly check the status of
these and ensure any hard dependencies (not suggestions or recommendations)
are installed before returning.
Consider the situation (where -> means 'depends on'):
X -> A,E
A -> B,E
E -> B
B -> C
Currently X would install A and E. When installing A the packages B, E
and C would be marked as "to install". When the package B is considered
the second time (as a dependency of E rather than A), it would install
straight away even though C was not currently installed, just marked
as needing to be installed.
The patch changes the behaviour so B can't install until C really is installed.
This change is required to run the postinst scripts in the correct order.

It appears that the opkg_internal_use_only provides string was introduced to
bandaid over problems with assuming that the pkg->provides, pkg->provides_str
and pkg->provides_count are all the same length. As each pkg provides itself,
the pkg->provides array was one longer than the str and count fields. Most of
the uses of pkg->provides did not take this into account.
This behaviour has been changed. pkg->provides is now pkg->provides_count long
and it is pkg->provides_str which is shorter by one.
Associated dead code has also been removed.
