0fd322f812 [legacy] Fix ZSTDv0*_decodeSequence() 
* Version <= 0.5 could read beyond the end of `dumps`, which points into
  the input buffer.
* Check the validity of `dumps` before using it, if it is out of bounds
  return garbage values. There is no return code for this function.
* Introduce `MEM_readLE24()` for simplicity, since I don't want to trust
  that there is an extra byte after `dumps`.

82d5a9870e [visual] Compile with ZSTD_MULTITHREAD=1 
This branch `appveyorTests` runs the tests that `master` runs, so
passing Appveyor means that the tests are fixed.

de0499f7fa [libzstd] Require ZSTD_MULTITHREAD to create a ZSTDMT_CCtx 
ZSTDMT was broken when compiled without ZSTD_MULTITHREAD defined,
because `ZSTD_CCtx_setParameter(cctx, ZSTD_c_nbWorkers, nbWorkerss)`
failed. It was detected by the MSVC test which runs the fuzzer with
multithreading disabled.

This is a very niche use case of a deprecated API, because the API is
inefficient and synchronous, since `threading.h` will be synchronous.
Users almost certainly don't want this, and anyone who tested their code
should realize that it is broken. Therefore, I think it is safe to
require `ZSTD_MULTITHREAD` to be defined to use ZSTDMT.

1e01560b83 fixed timespec_get() initialization bug on some targets 
not sure why, but msan fires an "unitialized variable" error
when time gets properly initialized by timespec_get().
Maybe in some cases, not all bytes of the structure are initialized ?
Or maybe msan fails to detect the initialization ?

Anyway, pre-initializing the variable before passing it to timespec_get() works.

885476fb5b FreeBSD_11 specific fix 
C11 mandates the definition of timespec_get() and TIME_UTC.
However, FreeBSD11 announce C11 compliance, but does not provifr timespec_get(),
breaking link stage for benchfn.
Since it does not provide TIME_UTC either, which is also required by C11,
test this macro: this will automatically rule out FreeBSD 11 for this code path
(it will use the backup C90 path instead, based on clock_t).

The issue seeems fixed in FreeBSD 12.
