Fix curly braces style Remove useless empty lines

Add lots of unique tags to error log messages

mod_proxy: Make ap_proxy_retry_worker() into an optional function. Allows mod_lbmethod_bybusyness, mod_lbmethod_byrequests, mod_lbmethod_bytraffic and mod_lbmethod_heartbeat to be loaded without mod_proxy yet being present, which happens when modules are loaded in alphabetical order.

Move useful and shared balancer stuff to the shm slot... Provide hooks for post-config/runtime addition of balancers.

Implement draining capability for proxy workers... only accept sticky on these puppies.

Cleanup... most don't need apr_hooks.h at all...

Implement reset() funcs for the LBmethods...

More movement to shared stuff...

Use the new APLOG_USE_MODULE/AP_DECLARE_MODULE macros everywhere to take advantage of per-module loglevels

server_rec *r... Oops should be server_rec *s.

Arrange the proxy_balancer_method: - Put context back after the finder(). - Use server_rec as second parameter for reset() and age(). - Add the call for reset().

Change the order of mod_proxy and mod_proxy_balancer child_init(). Change the balancer workers area to the address of workers instead copying the workers. Arrange lbmethod accordingly. Move the creation of conf->forward worker to mod_proxy child_init().

Fold in initial template for methods to be able to reset (initialize) and "age" their data, useful when adding new workers, or when workers come back into the fold.... Logic and code to come in a bit :)

Correct logic with non-seq lbsets config'ed

Add in independent bytraffic lbmethod
