Make sure that $(INCLUDEDIR) exists before copying the headers there.
Otherwise, the contest of header files is copied over
$(DESTDIR)$(INCLUDEDIR), making it a regular file.
While at it, remove $(DESTDIR)$(INCLUDEDIR) from the list of directories
to create in the install-pc target. The install-pc target does not need
this directory.

It's actually a bug in ZSTD_compressBegin_usingCDict()
which would pass a wrong pledgedSrcSize value (0 instead of ZSTD_CONTENTSIZE_UNKNOWN)
resulting in wrong window size, resulting in downsized seqStore,
resulting in segfault when writing into the seqStore later in the process.
Added a test in fuzzer to cover this use case (fails before the patch).
Whilst working on the Reproducible Builds effort [0], we noticed
that zstd could not be built reproducibly.
This is due to the manual page encoding the number of CPUs from the
build machine and thus varies across builds.
This was originally filed in Debian as #897904 [1].

The new advanced API basically set `requestedParams = appliedParams` when
using a dictionary. This halted all parameter adjustment, which can hurt
compression ratio if, for example, the window log is small for the first
call, but the rest of the files are large.
This patch fixes the bug, and checks that the `requestedParams` don't change
in the new advanced API when using a dictionary, and generally in the fuzzer.
FIO would keep presenting data after an LZ4F decoding error
resulting in a NULL pointer dereference
when associated with older liblz4 version (< v1.8.1.2)
It can have other effects, such as pulling in extra libraries. Without it,
riscv build fails with undefined reference to `__atomic_compare_exchange_1'.
Zstdmt uses prefixes to load the overlap between segments. Loading extra
positions makes compression non-deterministic, depending on the previous
job the context was used for. Since loading extra position takes extra
time as well, only do it when creating a `ZSTD_CDict`.
Fixes#1077.
OpenBSD uses md5 instead of md5sum, and has no device called full.
With this patch, make check runs until #1088. With the assumption made
in the issue make check runs succesfully.
