This approach isn't used anymore. Now we start the archive building with
parameters to pyrogeneis.
Refs #2241 (the code used g_ScriptingHost which is going to be removed)
This was SVN commit r14102.
archive: pretty much done except for trace and archive_builder
IO: io_manager still needs to be fixed/revised (especially WRT buffer
and alignment management)
posix: done
vfs: need to complete vfs_mount and tie it in to vfs.cpp
dir_util: needs further revisions (VFS interface changed since then)
This was SVN commit r5475.
