[PATCH] wwwstream::oneshot => html_oneshot

[PATCH] wwwstream::oneshot => html_oneshot

[Eric Wong]

And use Exporter to make our life easier, since WwwAltId was
using a non-existent PublicInbox::WwwResponse namespace in error
paths which doesn't get noticed by `perl -c' or exercised by
tests on normal systems.

Fixes: 6512b1245ebc6fe3 ("www: add endpoint to retrieve altid dumps")
