tests: ensure that TEST_NGINX_USE_STAP is unset when TEST_NGINX_USE_HUP is set.
tests: made two systemtap-based test cases less possible to fail in slow testing mode.
bugfix: the debug log message "lua set uri jump to <uri>" generated by ngx.req.set_uri(uri, true) was wrong for <uri> was the old URI.
bugfix: request hung when rewrite cycled in ngx.req.set_uri(uri, true) instead of throwing out an error log message and a 500 page properly. thanks Calin Don for the report.
feature: ngx.location.capture and ngx.location.capture_multi now return a lua table with the boolean field "truncated", which indicates whether the subrequest response body is truncated. bugfix: we no longer override the subrequest response status code later when error happens.
fixed a test case that might fail in slow testing modes.
removed too short proxy read timeout settings in two cases that are expected to pass.
added error log checks in 000--init.t.
updated tests to reflect recent changes in the upstream_truncation patch for the nginx core.
merged "master" branch to "timer".
