Sergei Trofimovich 68a70e45a1 x86 asm: mark stack as non-executable 
Gentoo's `scanelf` QA tool detects writable/executable stack
of assembly-writtent files as:

```
$ scanelf -qRa  .
 0644 LE !WX --- ---     ./src/strategies/x86_asm/.libs/picture-x86-asm-sad.o
 0644 LE !WX --- ---     ./src/strategies/x86_asm/.libs/picture-x86-asm-satd.o
 0644 LE !WX --- ---     ./src/strategies/x86_asm/picture-x86-asm-sad.o
 0644 LE !WX --- ---     ./src/strategies/x86_asm/picture-x86-asm-satd.o
```

Normally C compiler emits non-executable stack marking (or GNU assembler
via `-Wa,--noexecstack`).

The change adds non-executable stack marking for yasm-based assmbly files.

https://wiki.gentoo.org/wiki/Hardened/GNU_stack_quickstart has more details.

Pauli Oikkonen c5cd03497e Require BMI and ABM instruction sets for AVX2 build 
AVX2 support on a processor should always imply BMI and ABM support.
The lzcnt and tzcnt instructions have more suitable semantics in the
corner case that source word is 0, and allow us to even handle that
scenario without a branch. Apparently Visual Studio will already
include this support when building with AVX2 enabled, so only the
automake files need to be tweaked.

Arttu Ylä-Outinen c438bb4a19 Add an option to skip CABAC for residual costs 
Adds command line option --fast-residual-cost=<limit>. When QP is below
the limit, estimates the cost of coding the residual coefficients from
the sum of absolute coefficients. Skipping CABAC is not worth it with
high QPs because there are fewer coefficients so CABAC is not as slow.

Arttu Ylä-Outinen cb06cfeadb Drop temporary arrays in bipred search 
Changes bipred search to use the original source and reconstruction
arrays directly instead of copying them.

Arttu Ylä-Outinen 6f506be12d Drop dynamic allocation from bipred search 
Moves the temporary LCU struct used in bipred search from the heap to
the stack. The single malloc call was a huge bottleneck in bipred.

Arttu Ylä-Outinen 7155dd0db7 Add negative references to L1 list 
Changes reference index list creation so that the negative references
are added to L1 in addition to L0 when biprediction is enabled and no
reordering of pictures is done. Biprediction can now be used with the
low-delay GOP structure.

Arttu Ylä-Outinen 4b24cd03a2 Update for crypto++ 6.0.0 compatibility 
Changes the crypto module to use unsigned char instead of byte. The byte
typedef is no longer included in the global namespace in crypto++ 6.0.0.
See https://github.com/weidai11/cryptopp/issues/442.

Fixes #184.

Arttu Ylä-Outinen 8c53417006 Check zero coefficient cost for inter 
Checks the cost of flushing all coefficients of an inter block to zero.
This is much faster than doing full RDOQ but can still reduce bitrate
significantly. Encoding speed is increased since fewer coefficient bits
have to be coded with CABAC.

Moves code for reconstructing all PUs in an inter CU to a new function
kvz_inter_recon_cu in inter.c.

Arttu Ylä-Outinen 405b8c1069 Refactor inter MVD cost functions 
Moves duplicate code for writing the MVD of a single motion vector from
kvz_get_mvd_coding_cost_cabac and encoder_inter_prediction_unit to a new
function.

Arttu Ylä-Outinen c1cca1ad7f Refactor inter MV candidate selection 
Moves duplicate code for checking the best MV candidate from functions
calc_mvd_cost, search_pu_inter_ref and search_pu_inter to a new
function.

Arttu Ylä-Outinen 9067aa4535 Remove an unnecessary copy in SMP/AMP search 
SMP/AMP search is performed using a lower work tree level than the
normal inter search so the prediction info must be copied up if an
SMP/AMP mode is chosen. Previously pixels and coefficient were copied as
well. Changed to only copy prediction info.

Arttu Ylä-Outinen 0a69e6d18f Fix selection of transform function for 4x4 blocks 
DST function was returned for inter luma transform blocks of size 4x4
even though they must use DCT. Fixed by checking the prediction mode of
the block in addition to whether it is chroma or luma.

Arttu Ylä-Outinen 649113a821 Fix inter search being used for 4x4 blocks 
When 4x4 intra blocks are enabled and inter search is limited to 16x16
and larger blocks, it is possible that inter search is accidentally done
for 4x4 blocks. Fixed by checking that block size is at least 8x8 before
doing inter search.

Ari Lemmetti 14892fda00 Replace simple coefficient cost estimation with CABAC. Substantial improvement. 
Approximation proved to be too inaccurate while not giving actually that much speedup.
