blosc: updated to 1.16.3

Release 1.16.3
Fix for building for clang with -march=haswell.
Fix all the known warnings for GCC/Clang. Still some work to do for MSVC
in this front.
Due to some problems with several CI systems, the check for library symbols
are deactivated now by default. If you want to enforce this check, use:
cmake .. -DDEACTIVATE_SYMBOLS_CHECK=ON to re-activate it.

Release 1.16.2
Correct the check for the compressed size when the buffer is memcpyed. This
was a regression introduced in 1.16.0.

Release 1.16.1
Fixed a regression in 1.16.0 that prevented to compress empty buffers
Zstd updated to 1.3.8

Release 1.16.0
Now the functions that execute Blosc decompressions are safe by default
for untrusted/possibly corrupted inputs. The additional checks seem to
not affect performance significantly (see some benchmarks), so
this is why they are the default now.

The previous functions (with less safety) checks are still available with a
'_unsafe' suffix. The complete list is:

blosc_decompress_unsafe()
blosc_decompress_ctx_unsafe()
blosc_getitem_unsafe()
Also, a new API function named blosc_cbuffer_validate(), for validating Blosc
compressed data, has been added.

Fixed a bug in blosc_compress() that could lead to thread deadlock under
some situations.

Fix data race in shuffle.c host_implementation initialization.
