[repacker] recursively duplicate nodes during isolation.
...
If a node is duplicated during isolation then any children it has will have incoming links from outside the subgraph (from the duplicated node and the original node), so they must be duplicated too.

[repacker] begin implementing the ability to isolate extension subtables.
...
Adds isolate_subgraph operation to the repacker. This severs any links from outside a subgraph by duplicating the affected vertices. This will be used to isolate the subgraphs of a extension subtable from the rest of object graph. Thus allowing the extension subtable to be packed far away from the rest of the objects.

[subset] Fix subset_offset_array adding unused space to serializer.
...
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.

[meson] Add ragel subproject
...
If ragel 6.10 is not found, build it from source.
Seems to work, except that ragel uses exceptions and we configure
HarfBuzz build to not use exceptions, and I can’t find away to enable
exceptions only for the ragel subproject. I had to remove cpp_eh=none
from default options and try to disable exceptions in MSVC manually
(other compilers are already handled).

Ragel 7 is also not stable from upstream's point of view.
This uses “version” argument find_program(), which was introduced in
meson 0.52.0, so I raised the minimum required meson version
accordingly.
