If an SSL connection becamse disabled or suspended before became open,
it could (under the right circumstances) wind up without ever getting
its write callback disabled.

The most correct fix is probably more subtle, and involves checking
all caseswhen a write callback is enabled or disabled.  This fix is

Correct logic on disabling underlying bufferevents when disabling a filter

Previously, whenever writing was disabled on a bufferevent_filter (or
a filtering SSL bufferevent), we would stop writing on the underlying
bufferevent.  This would make for trouble, though, since if you
implemented common patterns like "stop writing once data X has been
flushed", your bufferevent filter would disable the underlying
bufferevent after the data was flushed to the underlying bufferevent,
but before actually having it written to the network.

Now, we have filters leave their underlying bufferevents enabled for
reading and writing for reading and writing immediately.  They are not
disabled, unless the user wants to disable them, which is now allowed.
To handle the case where we want to choke reading on the underlying
bufferevent because the filter no longer wants to read, we use
bufferevent_suspend_read().  This is analogous to the way that we use
bufferevent_suspend_write() to suspend writing on a filtering
bufferevent when the underlying bufferevent's output buffer has hit
its high watermark.

Fix serious bugs in per-bufferevent rate-limiting code

they had run out of bandwidth.  Under some circumstances, this could
cause a bufferevent to never actually refill one of its
rate-limiting buckets.

Also, the code treated setting a per-connection rate-limit on a
connection that already had a group-limit as if it were changing the

Make default signal backend fully threadsafe

Jason Toffaletti discovered with helgrind that our signal handler was
messing with evsig_base, which can be set from lots of places in the
code.  Ordinarly, we'd just stick a lock on it, except that it is
illegal (and genuinely error-prone) to call pthread_mutex_acquire()
from inside a signal handler.

The solution is to only store the fd we write to in a static variable,
write the signal number to the fd, and put evsig_cb in charge of
activating signal events.

I have no idea how we'll cope if we want to enable this to handle
siginfo (where available) in the future.

Warn when using the error-prone EV_SIGNAL interface in an error-prone way.  Also, fix a couple of race conditions in signal.c

When using the signal.c signal backend, Libevent currently only allows
one event_base to actually receive signals at a time.  (This has been
the behavior since at least 1.4 and probably much earlier.)  Now, we
detect and warn if you're likely to be racing about which signal goes
to which thread.

We also add a lock to control modifications of the evsig_base field,
to avoid race conditions like those found by Jason Toffaletti.

Also, more comments.  Comments are good.
