Fix all warnings in the main codebase flagged by -Wsigned-compare
Remember, the code
int is_less_than(int a, unsigned b) {
return a < b;
}
is buggy, since the C integer promotion rules basically turn it into
int is_less_than(int a, unsigned b) {
return ((unsigned)a) < b;
}
and we really want something closer to
int is_less_than(int a, unsigned b) {
return a < 0 || ((unsigned)a) < b;
}
.
Suggested by an example from Ralph Castain

Fix a nasty dangling-event bug when using rate-limiting groups
When we freed a bufferevent that was in a rate-limiting group and
blocked on IO, the process of freeing it caused it to get removed
from the group. But removing the bufferevent from the group made
its limits get removed, which could make it get un-suspended and in
turn cause its events to get re-added. Since we would then
immediately _free_ the events, this would result in dangling
pointers.
Fixes bug 3041007.

Functions to manipulate existing rate limiting groups.
This patch adds a function to change the current rate limit of a rate
limiting group, and another to free an empty rate limiting group.

Functions to view and manipulate rate-limiting buckets.
We need these for Tor, and other projects probably need them too. Uses
include:
- Checking whether bandwidth is mostly-used, and only taking some
actions when there's plenty of bandwidth.
- Deducting some non-bufferevent activities from a rate-limit group.

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.

Rate-limiting for bufferevents; group and individual limits are supported.
The fairness algorithms are not the best, not every bufferevent type
is supported, and some of the locking tricks here are simply absurd.
Still, this code should be a good first step.
