Implement it using av_buffersrc_add_ref.

This will make merging with the audio part easier.

This will make merging the check with the audio part easier.

This function merges the features of
av_vsrc_buffer_add_video_buffer_ref() and
av_buffersrc_buffer().

Compared to av_opt_ptr, accessors bring:

- better performance (negligible);
- compile-time type check;
- link-time existence check
  (or at worst, a dynamic linker error instead of a NULL dereference).

The option is related to the timecode, the new name clearly specifies the
context. Also it allows to list the option close to the other timecode
options.

Use the more expressive names draw_expr and draw_pexpr, also more
consistent.

They are options, not expression parameters.

Starting with version 4.7, gcc properly supports unaligned
memory accesses on ARM.  Not using the inline asm with these
compilers results in better code.

With a dereferenced type-cast pointer as memory operand, gcc 4.6
and later will sometimes copy the data to a temporary location,
the address of which is used as the operand value, if it thinks
the target address might be misaligned.  Using a pointer to a
packed struct type instead does the right thing.

The 16-bit case is special since the ldrh instruction addressing
modes are limited compared to ldr.  The "Uq" constraint produces a
memory reference suitable for an ldrsb instruction, which supports
the same addressing modes as ldrh.  However, the restrictions appear
to apply only when the operand addresses a single byte.  The memory
reference must thus be split into two operands each targeting one
byte.  Finally, the "Uq" constraint is only available in ARM mode.
The Thumb-2 ldrh instruction supports most addressing modes so the
normal "m" constraint can be used there.
