fffmpeg -> ffmpeg

Ref #3682 and #3666
Now, we have
[022d6ffc] main tls client debug: TLS client session initialized
instead of
[004e6ffc] gnutls tls client error: Certificate could not be verified

However, this still doesn't work fine, since we got a:
"access_http acccess error: failed to read answer"

And use autoreconf instead of autogen for tremor.

VLC will fallback to lavc

The whole module_config_t is loaded/saved anyway, which is sufficient
for immediate values.

this also prepares a mainwindow object and includes some clean-up

Use the high order bits for the intrinsic value type (hint, integer, float
or string) and the low order ones for the more specific sub-types.

Values are 8-bits.

Variable types and configuration item types are separate. Fortunately
they use the same bits so it worked fine.

If the high nibble is set, the type is item type and the low nibble is
necessarily zero.

The FFmpeg configure script autodetects those correctly. Of course,
this assumes that the compiler defaults or flags are adequate.
