c11b0b96f8 fix #563 
ensure that building test tools preserves compilation flags
including -std=c99 and -std=c++11
when invoked with CFLAGS pre-set
so that it properly compiles with gcc <= 4.8 .

reported by @t-mat.

2c992d0cc7 merge xxh3 implementation within xxhash.h 
xxh3.h is no longer necessary
but remains available,
in case some programs do #include "xxh3.h" directly.

Also : bumped version number to v0.8.0

c994f5c9ef Fix copyright years 
- Replace '-present' with '-2020' (fixes #329)
 - Use correct format: Copyright (C) <year> <name of author>
 - Fix some obviously incorrect years from copy/paste i.e. avoid time travel

87e7d8b999 More typos, add some more documentation 
- Remove most remaining spaces before punctuation
 - Fix a few missed copyright messages
 - Document the timer resolution workaround
 - Document XXH_mult32to64
   - I compiled GCC 3.2 and 4.2 just to test this, both are affected.
   - Make sure we downcast for __emulu
 - Other minor fixes

Work in progress.

 - Fix many spelling/grammar issues, primarily in comments
 - Remove most spaces before punctuation
 - Update XXH3 comment
 - Wrap most comments to 80 columns
 - Unify most comments to use the same style
 - Use hexadecimal in the xxhash spec
 - Update help messages to better match POSIX/GNU conventions
 - Use HTML escapes in README.md to avoid UTF-8
 - Mark outdated benchmark/scores

ac897bec29 alignment hint for auto-vectorizer 
works great for AVX2, but not for SSE2 (?)

also : use char* to explicitly tell that no alignment guarantee is being made

also : slightly changed start address of last stripe's secret (-1)
so that it doesn't correspond to scrambler's secret.
