08b94f160a configure: Don't pass MSVC compiler options -M[TD] to armasm 
The -MD option (for enabling a dynamically linked crt) gets interpreted
as a cpp option for generating dependency information (into a file named
'-.d', when preprocessing to a pipe). We shouldn't be passing
any and all C compiler flags to armasm (which is a plain assembler,
only with cpp bolted on via gas-preprocessor), but these are the
main conflicting ones.

7acdd3a127 hevc_filter: avoid excessive calls to ff_hevc_get_ref_list() 
1) each of the loops run within a single CTB, so the relevant reference
list is constant
2) when that CTB is, or lies on the same slice as, the current one, we
can use a simple access instead of a relatively expensive call to
ff_hevc_get_ref_list()

ad1ee5fa75 avcodec: Undeprecate reordered_opaque 
It allows attaching other external, opaque data to the frame and passing it

than just the plain packet pts.  There is no way to cleanly achieve this
without the field.

7b588bb691 svq1: do not modify the input packet 
The input data must remain constant, make a copy instead. This is in
theory a performance hit, but since I failed to find any samples
using this feature, this should not matter in practice.

Also, check the size of the header, avoiding invalid reads on truncated
data.

ed6d9ce914 configure: Include the armcc build number in the compiler identification 
This tries to find the most expressive part of the output of
armcc --vsn to include, giving a compiler identification of
"ARM Compiler 5.04 update 2 (build 82)" instead of just
"ARM Compiler 5.04" for armcc 5.0.

4.x versions of armcc output the following, for "armcc --vsn":
ARM C/C++ Compiler, RVCT4.0 [Build 925]
For evaluation purposes only
Software supplied by: ARM Limited

ARM C/C++ Compiler, 4.1 [Build 894]

Component: ARM Compiler 5.04 update 2 (build 82)
