A new key & value API lets us gain access to newly added parameters
without adding explicit support for them in our wrapper. Add an
option utilizing this functionality in a similar manner to other
encoder libraries' wrappers.

In case trellis is outside of 0..23, an invalid shift and/or a signed
integer overflow happens; furthermore, it can lead to the request to
allocate nonsense amounts of memory. So validate first.

MJPEG does not have a single quantiser scale, so this does not fit into
the intended API use.
This removes the last use of the long-deprecated QP table API.
The way SRT's async / epoll-based IO works is that the event status is stored
in the epoll containers. That is, if an event occurs on an SRT socket, and that
SRT socket isn't part of any epoll container, then that event is lost. If we
later add that socket to an epoll container, we still won't receive the event
even if it wasn't serviced.
Therefore we create the epoll and put the fd into it right after the connection
is established.

Both AC-3 encoder share the same options, yet they are nevertheless
duplicated in the binary; and the options applying to the EAC-3 encoder
are a proper subset of the options for the AC-3 encoders, so that it can
use the same options as the former by putting the options specific to
AC-3 at the front. This commit implements this.

The fixed-point AAC decoder is the only user of the fixed-point sinewin
tables from sinewin; and it only uses a few of them (about 10% when
counting by size). This means that guarding initializing these tables by
an AVOnce (as done in 3719122065) is
unnecessary for them. Furthermore the array of pointers to the
individual arrays is also unneeded.
Therefore this commit moves these tables directly into aacdec_fixed.c;
this is done by ridding the original sinewin.h and sinewin_tablegen.h
headers completely of any fixed-point code at the cost of a bit of
duplicated code (the alternative is an ugly ifdef-mess).
This saves about 58KB from the binary when using hardcoded tables (as
these tables are hardcoded in this scenario); when not using hardcoded
tables, most of these savings only affect the .bss segment, but the rest
(< 1KB) contains relocations (i.e. savings in .data.rel.ro).

If a target to be built includes a template file, the target's .d file
includes the template file as a prerequisite; if the code were changed so
that the template file no longer exists, one would get an error from
make that it has no rule for the template file target. Therefore add a
dummy rule for template files to make deleting them possible.
