When a socket callback has a timeout, an associated timer event is used to
remove the sockets from the pollset and call a timeout function.
* This includes a noteworthy change to the main event loop. Previously,
we would call epoll, then process the timer events, then iterate through the
poll results. After this patch, the timer events are processed before the poll()
a _non-queued_ action can change the pollset conents (a users timed callback
function conversely could easily sit in a queue while the main thread continues
down into epoll)
* timer events can now have sockets associated with them, those sockets are
removed from the pollset when the timer event fires w/o a queue to the worker.
* timer events now have a canceled flag that can be toggled without locking
the timer list.
* Drop the severity of some wstunnel messages from DEBUG to TRACE1
* Lift the restriction on using asynchronous websockets connections but having
an idle timeout

distinguished names based on expressions to be escaped correctly to
guard against LDAP injection.
Note: this requires at least APR v1.6.0 or above for the apr_escape API.

happen across threads and are only protected from
other skiplist operations.

Don't include "\" in the printable form of the data because
it will be escaped later in processing, and the extra escaping
throws off the alignment. Just filter it out like unprintable
characters.

Allows for several "connections" all resulting in
a single real connection that talks to the network.
Right now, nothing uses this though.

HttpContentLengthHeadZero - allow Content-Length of 0 to be returned on HEAD
HttpExpectStrict - allow admin to control whether we must see "100-continue"
This is helpful when using Ceph's radosgw and httpd.

Make sure an error log provider has initialized before trying to log to it.
(A log function may be called in a window between closing stderr and opening logs.)
