[PATCH 0/4] -httpd static file improvements

[Eric Wong <e@yhbt.net>]

Serving large static files to slow clients could lead to
public-inbox-httpd buffering data already in static files again
into a temporary file.

This was inefficient, and solving it in a generic way could
actually break other PSGI servers since their sendfile
optimizations don't handle 206 (partial content) responses
correctly.

So we make minor changes to the way PublicInbox::DS handles
write buffers and inject static files, offsets, and length
limits directly into the {wbuf} queue.

Eric Wong (4):
  http: eliminate short-lived cyclic ref for psgix.io
  wwwstatic: offload error handling to PSGI server
  ds: tmpio: store offsets per-buffer
  wwwstatic: wire up buffer bypass for -httpd
