cleanup: misc. (previously deferred)

dr_document_make in three identifier spellings becomes document_make,
which is what the file has been called since the rename.

The mixin import audit, a template declares its imports at template
scope and they are then visible in every scope it is mixed into (which
is how a template-level split once hijacked a UFCS lookup in code that
had not been touched). Disabling htmlSnippet's imports and rebuilding
names the consumers that were relying on them rather than on their own:
across twelve mixin sites, exactly one. metadata.d now imports the `to`
it uses. The templates keep their imports, their own functions needing
them, and narrowing those is a change of its own rather than a cleanup.

And the standing FIX in source_pod.d: the insert digest line for a non
pod source recorded the insert's path, where every other line in
digests.txt is a filename and a digest naming a file that is not in
the pod under that name cannot be checked against it.
