Add support for a "debug mode" to try to catch common errors.
Right now it only catches cases where we aren't initializing events,
or where we are re-initializing events without deleting them first.
These are however shockingly common.

Remove a needless include of rpc_compat.h
Nothing in evrpc.c was using rpc_compat.h, so it's best to take it
out, especially since it polluted our build process with GCC variadic
macros.
While we're at it, this patch puts an extra restriction on when the
variadic macros in rpc_compat.h are defined. Not only must GCC be the
compiler, but GCC must not be running in -ansi mode.

Check more internal event_add() calls for failure
Most of these should be unable to fail, since adding a timeout
generally always works. Still, it's better not to try to be "too
smart for our own good here."
There are some remaining event_add() calls that I didn't add checks
for; I've marked those with "XXXX" comments.

Functions to access more fields of struct event.
Once event_assign() or event_new() had been called, there was no way
to get at a copy of the event's callback, callback argument, or
configured events. This patch adds an accessor function for each, and
an all-fields accessor for code that wants to re-assign one field of
an event.
This patch also adds a function to return sizeof(struct event), so
that code with intense RAM needs can still retain ABI compatibility
between versions of Libevent without having to heap-allocate every
struct event individually.
The code here was first proposed by Pavel Pisa.

Allow http connections to use evdns for hostname looksups.
This was as simple as using bufferevent_connect_hostname instead of
calling connect() ourself, which already knows how to use an

evdns_getaddrinfo() now supports the /etc/hosts file.
The regular blocking evutil_getaddrinfo() already supported /etc/hosts
by falling back to getaddrinfo() or gethostbyname(). But
evdns_getaddrinfo() had no such facility. Now it does.
The data structure here isn't very clever. I guess people with huge
/etc/hosts files will either need to get out of the 1980s, or submit a
patch to this code so that it uses a hashtable instead of a linked
list.
Includes basic unit tests.

Make the initial nameserver probe timeout configurable.
When we decide that a nameserver is down, we stop sending queries to
it, except to periodically probe it to see if it has come back up.
Our previous probe sechedule was an ad-hoc and hard-wired "10 seconds,
one minute, 5 minues, 15 minutes, 1 hour, 1 hour, 1 hour...". There
was nothing wrong with having it be ad-hoc, but making it hard-wired
served no good purpose.
Now the user can set the initial timeout via a new
"initial-probe-timeout:" option; future timeouts back off by a factor
of 3 on every failure to a maximum of 1 hour.
As a side-benefit, this lets us cut the runtime of the dns/retry test
from about 40 seconds to about 3 seconds. Faster unit tests are
always a good thing.

Revise the locking API: deprecate the old locking callbacks and add trylock.
Previously, there was no good way to request different kinds of lock
(say, read/write vs writeonly or recursive vs nonrecursive), or for a
lock function to signal failure (which would be important for a
trylock mode).
This patch revises the lock API to be a bit more useful. The older
lock calls are still supported for now.
We also add a debugging mode to catch common errors in using the
locking APIs.

probably more issues. It should get tested on more platforms.

Implement queued timeouts for case where many timeouts are the same.
Libevent's current timeout code is relatively optimized for the
randomly scattered timeout case, where events are added with their
timeouts in no particular order. We add and remove timeouts with
O(lg n) behavior.
Frequently, however, an application will want to have many timeouts
of the same value. For example, we might have 1000 bufferevents,
each with a 2 second timeout on reading or writing. If we knew this
were always the case, we could just put timeouts in a queue and get
O(1) add and remove behavior. Of course, a queue would give O(n)
performance for a scattered timeout pattern, so we don't want to
just switch the implementation.
This patch gives the user the ability to explicitly tag certain
timeout values as being "very common". These timeout values have a
cookie encoded in the high bits of their tv_usec field to indicate
which queue they belong on. The queues themselves are each
triggered by an entry in the minheap.
See the regress_main.c code for an example use.

This function, bufferevent_socket_connect_hostname() can either use

Keep openssl errors associated with the right bufferevent object.
OpenSSL has a per-thread error stack, and really doesn't like you
leaving errors on the stack. Rather than discard the errors or force
the user to handle them, this patch pulls them off the openssl stack
and puts them on a stack associated with the bufferevent_openssl. If
the user leaves them on the stack then, it won't affect any other
connections.

Bufferevent support for openssl.
This code adds a new Bufferevent type that is only compiled when the
openssl library is present. It supports using an SSL object and an
event alert mechanism, which can either be an fd or an underlying
bufferevent.
There is still more work to do: the unit tests are incomplete, and we
need to support flush and shutdown much better. Sometimes events are
generated needlessly: this will hose performance.
There's a new encrypting proxy in sample/le-proxy.c.

Add a "ctrl" mechanism to bufferevents for property access.
OpenSSL uses something like this to implement get/set access for
properties on its BIOs, so that it doesn't need to add a pair of
get/set functions to the vtable struct for every new abstract property
it provides an accessor for.
Doing this lets us make bufferevent_setfd abstract, and implement an

IOCP, where available.
