*/*: update NGINX JavaScript: 0.8.4 -> 0.8.5 (+)

<ChangeLog>

*) Change: r.variables.var, r.requestText, r.responseText,

s.variables.var, and the "data" argument of the s.on() callback
with "upload" or "download" event types will now convert bytes
invalid in UTF-8 encoding into the replacement character.  When
working with binary data, use r.rawVariables.var, r.requestBuffer,
r.responseBuffer, s.rawVariables.var, and the "upstream" or
"downstream" event type for s.on() instead.

add(), set() and incr().
