dvb: update build with ffmpeg 3.0.

dvb.media_addon: Let C++ use C99 math features.

- This get rids of the complain "'UINT64_C' was not declared in this scope" and
allows us to remove the (now superflous) declaration of UINT64_C.
- No functional change intended.

DVB media addon: Fix debug build.

- Compiling dvb.media_addon with DEBUG on fails with error message:
generated/objects/haiku/x86/debug_1/add-ons/media/media-add-ons/dvb/
MediaFormat.o: In function `av_log2_c': /boot/home/Development/haiku-a4/
generated/build_packages/ffmpeg-0.10.2-r1a4-x86-gcc2-2012-08-30/common/
include/libavutil/common.h:80: undefined reference to `ff_log2_tab'
collect2: ld returned 1 exit status"

- Research done to narrow down the solution space:
- ff_log2_tab is a array that is nowhere needed in the dvb.media_addon
- ff_log2_tab is defined as an extern array in the ffmpeg header file
libavutil/common.h
- ff_log2_tab is used in the inline function av_log2_c (libavutil/common.h)
which doesn't get optimized away when compiling with debug information
- MediaFormat.cpp needs only some Codec-IDs from the ffmpeg header file
avcodec.h

- The following fixes were tried:
- Trying to eliminate unused debug symbols with compilation
flag -feliminate-unused-debug-types (see gcc documentation
http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Debugging-Options.html#Debugging-Options)
by adding the following lines to UserBuildConfig
AppendToConfigVar C++FLAGS : HAIKU_TOP src : -feliminate-unused-debug-types : global ;
AppendToConfigVar CCFLAGS : HAIKU_TOP src : -feliminate-unused-debug-types : global ;
-> Failed, because flag -feliminate-unused-debug-types is not supported by GCC 2.95.3

- Trying to eliminate unused debug symbols in the linker stage
-> This worked, by removing the LINKFLAG "-Xlinker --no-undefined" when
linking all objects into the dvb.media_addon we are getting our addon
with debug symbols.

- Final solution:
- Instead of adding/removing flags, we just add the missing implementation
for the ff_log2_tab array in MediaFormat.cpp. This -feels- the seems to
be the cleanest solution as it is more obvious what's goin' on compared
to hiding the solution in the Jamfile.

Very ugly hack to make DVB addon find the MPEG and AC3 codecs.
Something appeards to be very wrong with codec registration.
