e3e0775cc8 [API] Add ZSTD_c_stable{In,Out}Buffer parameters 
This commit adds the parameters and sets the value in the CCtxParams
but it does not do anything with the value.

e2581d9572 [lib] Set appliedParams in zstdmt mode 
Previously only `nbWorkers` was set. Set all parameters, because that is
what is expected. This is needed for the `ZSTD_c_stable{In,Out}Buffer`
parameters.

d0436b2a45 automatically detect configuration changes 
Makefile now automatically detects modifications of compilation flags,
and produce object files in directories dedicated to this compilation flags.
This makes it possible, for example, to compile libzstd with different DEBUGLEVEL.
Object files sharing the same configration will be generated into their dedicated directories.

Also : new compilation variables
- DEBUGLEVEL : select the debug level (assert & traces) inserted during compilation (default == 0 == release)
- HASH : select a hash function to differentiate configuration (default == md5sum)
- BUILD_DIR : skip the hash stage, store object files into manually specified directory

911dbdbb4b build libzstd.so from object files 
%.o object files generated for dynamic library
must be different from those generated for static library.

Due to this difference, %.o were so far only generated for the static library.
The dynamic library was rebuilt from %.c source.

This meant that, for every minor change, the entire dynamic library had to be rebuilt.

This is fixed in this PR :
only the modified %.c source get rebuilt.

43c0054405 aarch64: use __ARM_NEON instead of __aarch64__ to control use of neon 
There are compilation environments in aarch64 where NEON isn't
available. While these environments could define ZSTD_NO_INTRINSICS,
it's more fail-safe to use the more specific symbol to know if NEON
extensions are available.

__ARM_NEON is the proper symbol, defined in ARM C Language Extensions
Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
sources suggest __ARM_NEON__, but that's the obsolete spelling from
prior versions of the standard.
