Mark Hatle - Aug. 14, 2013, 8:30 p.m.
This adds a new argument to opkg-cl, --add-exclude, which is
used to add package names to the list of packages to exclude
from the install.

If an excluded package is needed for the install to resolve,
an error will be generated.  Recommended packages will not
generate an error.

+Add a way to exclude specific packages from the install
+
+When an excluded package is required by another package an error
+will be generated.  If the excluded package is only recommended,
+no error will be generated.
+
+The lifespan of the exclude_list covers the execution of the process,
+so there is no need to free the data.
