7ca6c1ff78 Fix of rbtree lookup on hash collisions.
Previous code incorrectly assumed that nodes with identical keys are linked
together.  This might not be true after tree rebalance.

Patch by Lanshun Zhou.

73d0b6a721 Limit req: number of cleanup calls reduced.
Doing a cleanup before every lookup seems to be too aggressive. It can lead to
premature removal of the nodes still usable, which increases the amount of work
under a mutex lock and therefore decreases performance.

In order to improve cleanup behavior, cleanup function call has been moved right
before the allocation of a new node.

8dab3b5a39 Limit req: allocation and initialization of a new node moved to the lookup
function.

5f5205ba87 Limit req: improved error handling when parsing "zone" parameter of
"limit_req_zone" directive; minimum size of zone is increased.

Previously an unsigned variable was used to keep the return value of
ngx_parse_size() function, which led to an incorrect zone size if NGX_ERROR
was returned.

The new code has been taken from the "limit_conn_zone" directive.

39f01e526f Fixed limit_conn_log_level/limit_req_log_level inheritance.
The directives did not work if there were no limit_conn/limit_req specified on
the same level.

622721a598 an excess was logged as 0.000 if requests were limited without delay:
*) use a real excess value instead of non-updated limit_req rbtree node field,
*) move inactivity queue handling inside ngx_http_limit_req_lookup()
   since the node is not required outside the lookup function;

the bug has been introduced in r3184
