This was removed erroneously in
046f081b46. This define still is
necessary for getting MAP_ANONYMOUS defined on linux/glibc,
despite the define reshuffling done in that commit.

Without MAP_ANONYMOUS defined, the mprotect calls for setting the
generated mmx2 scaler code pages executable are left out, causing
crashes if that codepath is chosen.

This patch fixes scaling from 192x144 to 320x240 with
-sws_flags fast_bilinear, which crashes on linux at the
moment.

A value shifted left by >31 needs to have a 64-bit type.
As there are no defined channels in this range, the fix
is purely theoretical at this point, although it does
avoid some invalid shifts triggering the overflow
checker.

It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

In particular, make the json writer write size values, fix regression
introduced with the addition of the print_val() macro.

This makes the two pass encoding with x264 working with -f null - as
first pass.

This is required to fulfill avcodec_decode_video2() promise to return
the number of consumed bytes on success.

Add all seven test bitstreams of Coding Technologies "aacPlus Decoder
Check Package". The streams cover different ways to signal SBR and PS
in different formats.

As the filter uses the default start frame, the cleanup done by the
default end frame is needed.

Casting the left-most byte to unsigned avoids an undefined

Also reduce verbosity for the unsupported stream message, use
an AVFormatContext for av_log and and print the tag of the
