[fuzz] Add libFuzzer targets
* The regression driver serves both as a regression test, and as a binary for afl-fuzz.
* Next, we want to check in a seed corpus for each target. Then we can run the regression
test binary on them on Travis or Circle CI.

removed gcc compilation flag -Wbad-function-cast
It makes it more difficult to directly cast the result of a function,
requiring to store the result in an intermediate variable.
It does not necessarily help readability,
and this restriction can be difficult to overcome in some constructions,
like some macros.
also : fixed minor Visual conversion warnings in datagencli.c

Merge remote-tracking branch 'upstream/dev' into btopt
* upstream/dev: (305 commits)
added test for ZSTD_estimateCStreamSize()
changed variable name, for clarity
fixed ZSTD_estimateCStreamSize()
shortened ZSTD_createCStream_Advanced()
fixed symbols test
added ZSTD_estimateDStreamSize()
changed name frameParams into frameHeader
regroup memory usage function declarations
separated ZSTD_estimateCStreamSize() from ZSTD_estimateCCtxSize()
bumped version number
added ZSTD_estimateCDictSize() and ZSTD_estimateDDictSize()
Updated ZSTD_freeCCtx()

merged CCtx and CStream as a single same object
cli : -d and -t do not stop after a failed decompression
added dev branch CircleCI badge
added dev branch Appveyor badge
keep dev branch status only
creates a binary archive without the `programs` directory
...
The new naming is more distinctive from ZSTD_frameParameters,
which is used during compression.
ZSTD_frameHeader is clearer in its intention to described frame header content.
It also implies we are decoding a ZSTD frame, hence we are at decoding stage.

updated ZSTD_estimateCCtxSize()
added a parameter streaming,
to estimate memory allocation size
when the CCtx is used for streaming (CStream).
Note : this function is not able to estimate
memory cost of a potential internal CDict
which can only happen when starting with ZSTD_initCStream_usingDict()

removed -g from DEBUGFLAGS
It inflates binary sizes, which is negative for the Windows build.
It also makes it impossible to check if 2 different source codes
get nonetheless compiled to the same binary,
since checksum will be different, due to integrated source code.
