swscale/utils: Derive range from YUVJ-pix-fmt only once
...
Currently, it is done once per slice-thread, leading to
one warning per slice-thread in case a YUVJ pixel format
has been originally used.
This also fixes the anomaly that said parameter are only
updated for the user-facing context (whose values are retrievable
via av_opt_get()) if slice-threading is not in use.
Fixes ticket #9860 .

swscale/utils: Factor initializing single slice context out
...
Initializing slice threads currently uses the function
(sws_init_context()) that is also used for initializing
user-facing contexts with the only difference being that
nb_threads is set to one before initializing the slice contexts.
Yet sws_init_context() also initializes lots of stuff
that is not slice-dependent, i.e. (src|dst)Range. This
currently only works because the code sets these fields
to the same values for all slice contexts. This is not
nice; even worse, it entails that log messages are printed
once per slice context (and therefore fill the screen).
This commit lays the groundwork to fix this.

fate/aacenc: increase tolerance for ln-128k test
...
The encoder is sensitive to changes in precision, and its test target
was a compromise. It was already close to failing on x87 FPUs.
ff_mdct_init used double precision entirely from the scale to computing
the MDCT exp tables. av_tx_init uses single-precision for the scale,
with a small input change which was enough to tip the test into failing on
x87 FPUs.
Increase the fuzz factor in line with other AAC encoder tests to fix.

avcodec/flashsvenc: Change check for first frame
...
AVCodecContext.frame_number is actually only incremented
in case encoding was successfull; if e.g. the ff_alloc_packet()
below fails, it won't be incremented and therefore it is possible
for the previous_frame buffer to be allocated for multiple
first frames, leaking every one except the last.
So check for whether there already is a previous frame instead.
