7011a42b1a rtmp: support strict rtmp servers 
In order to send or receive a stream FCPublish, FCSubscribe and _checkbw
are completely optional and often not implemented. releaseStream over a
non-existen stream might report an error instead of being silent.

5b170c0bea x86: remove FASTDIV inline asm 
GCC 4.3 and later do the right thing with the plain C code.  Earlier
versions in 32-bit mode generate one extra instruction, needlessly
zeroing what would be the high half of the shifted value.  At least
two gcc configurations miscompile the inline asm in some situations.

In 64-bit mode, all gcc versions generate imul r64, r64 followed by
shr.  On Intel i7 and later, this imul is faster 32-bit mul.  On
older Intel and all AMD, it is slightly slower.  On Atom it is much
slower.

Considering where the FASTDIV macro is used, any overall negative
performance impact of this change should be negligible.  If anyone
cares, they should file a bug against gcc and get the instruction
selection fixed.

66baa45801 configure: Drop fastdiv option 
There is no point in having the user disable any fastdiv macros.
Besides the condition implementation was broken and only disabled
the C implementation, but no platform specific assembly versions.

4264a0dd54 build: Make the E-AC-3 encoder select the AC-3 encoder 
The E-AC-3 encoder depends on almost all of the code of the AC-3
encoder, so it makes no sense to enable one without the other.

957521e7a4 fate: make Ut Video encoder tests use bitexact swscale flags 
The failures on various architectures and compilers on the RGB(A)
tests seem to have been because of one-off YCbCr->RGB conversion
results. This should make the conversion results match on most if
not all code paths.

Currently it takes a mask and value, such that options for which

shorter and simpler to understand.
