Working delay body and tests.
Depends on rb->filter_need_buffering and rb->buffered, as well as
corresponding changes in the request body reading code to work.
Might not be the best solution, as current body reading code relies
on rb->buffered to be properly set at various stages. Notably,
rb->buffered must be cleared when calling the next filter, since
the save body filter relies on it. Possible future improvements:
implement last buffer checking in the save body filter instead of
checking for (rb->rest == 0 && !rb->buffered).
The code uses its own event to implement delay timer. To remove the timer
in case of abnormal request termination a cleanup handler is added. While
in theory it is possible to use a timer on c->read instead, this implies
additional changes to the request body reading code. Custom event was chosen
to reduce complexity of changes needed.

Delay body filter module for nginx. This is a test module, to check request body filters buffering mechanism to be introduced. Example: location / { delay_body 1s; } The module will delay the request body processing for the configured time. To compile nginx with the delay body module, use the "--add-module <path>" option of nginx configure.
