luaunbound, lunbound, lua-unbound ... "kärt barn har många namn"

Some modules have _VERSION = "LuaModule x.y.z", so it is a bit weird
to show the name twice.

E.g. 'lxp' isn't that easy to guess that it's LuaExpat

Currently libevent and libunbound would show up under Lua modules but
they are not, so a separate section seems more appropriate.

Code reuse and one less module to import is nice.

net.cqueues previously relied on timers instead of fd events sometimes.
Under net.server_select, it would have called cq:loop() on every
iteration of the main loop, which was probably not optimal.

This approximates what happens if you add a timer far in the future,
then reschedule it to right now.

Why? Just look at all that code deleted!
watchfd is the prefered way to poll things that expose FDs for this
purpose, altho it was added after net.cqueues.

A cache miss can be expensive so having numbers on how often this occurs
may be valuable.

errors.

Reduces the overhead of having both util.timer and the timer handling
here, since they are very similar and now API-compatible.

E.g. net.server_epoll is very close and could easily be adapted to
support this.

Similar to util.ringbuffer (and shares almost identical API). Differences:
- size limit is optional and dynamic
- does not allocate a fixed buffer of max_size bytes
- focus on simply storing references to existing string objects where possible,
avoiding unnecessary allocations
- references are still stored in a ring buffer to enable use as a fast FIFO
Optional second parameter to new() provides the number of ring buffer segments. On
Lua 5.2 on my laptop, a segment is ~19 bytes. If the ring buffer fills up, the next
write will compact all strings into a single item.

Code existed in a separate project before merged into Prosody, so
util.promise was not always around.

These are not needed since the watchfd API is provided by all net.server
backends.

Most healthy queries will return well within this time, and the
new retry logic should help spread the cost of additional retries.

On timeout the query would be resent twice - once within
servfail(), and again inside the timeout callback.
This commit moves all retry logic to servfail().
