manifest: enable remove-project using path

Browse Source 
A something.xml that gets included by two different
files, that both remove and add same shared project
to two different locations, would not work
prior to this change.

Reason is that remove killed all name keys, even
though reuse of same repo in different locations
is allowed.

Solve by adding optional attrib path to
<remove-project name="foo" path="only_this_path" />
and tweak remove-project.

Behaves as before without path, and deletes
more selectively when remove path is supplied.

As secondary feature, a project can now also be removed
by only using path, assuming a matching project name
can be found.

Deletes a project from the internal manifest table, possibly
allowing a subsequent project element in the same manifest file to
replace the project with a different source.
@ -481,6 +482,17 @@ This element is mostly useful in a local manifest file, where
the user can remove a project, and possibly replace it with their
own definition.
The project `name` or project `path` can be used to specify the remove target
meaning one of them is required. If only name is specified, all
projects with that name are removed.
If both name and path are specified, only projects with the same name and
path are removed, meaning projects with the same name but in other
locations are kept.
If only path is specified, a matching project is removed regardless of its
name. Logic otherwise behaves like both are specified.
Attribute `optional`: Set to true to ignore remove-project elements with no
matching `project` element.
