Instead of filling a local array with the desired value and loading it,
load a single element and vec_splat() it to fill the vector.

Using this flag enables position-independent code even when not strictly
required.  It is impossible to use --disable-pic to forcibly disable PIC
when other properties mandate it.

There is a theoretical possibility to pass a very long string to ff_parse,
which could crash if allocated from the stack.  This allows the allocation
to be checked properly.

pred_order can never exceed 32, so always allocating that amount is safe
and not very wasteful.

The per-arch headers can define any combination of B/L/N variants.
This ensures that whatever is defined in an arch header gets used
for all equivalents not defined there.  E.g. on a little-endian
machine, AV_RN and AV_RL should give the same code.

We do the same for libschroedinger and already use pkg-config to generate
the CFLAGS for libdirac anyway, so there is no new dependency.
Thanks to Kovensky for reporting breakage on IRC.

When a frame is allocated using libschroedinger routines, the frame data size
does not match the actual frame size if the width is not a multiple of 16. So
we cannot do a straightforward memcpy of the frame returned by libschroedinger
into the FFmpeg picture as the stride differs from the width.

Fix this bug by allocating for the libschroedinger frame with the dimensions
in AVCodecContext within libavcodec and passing the frame to libschroedinger.
