This reverts commit a152b4c67a5266f611db4a2eac4a79003852a795.

check that the dictBuilder can be compiled
with only lib/common and lib/compress as dependencies.

Fix #1861: Restrict overlapLog Parameter When Not Built With Multithreading

Take ZSTD_parameters as a const pointer

'head -c BYTES' is non-portable.

'date -r FILE' is non-portable.

This parameter is unused in single-threaded compression. We should make it
behave like the other multithread-only parameters, for which we only accept
zero when we are not built with multithreading.

date(1) is used to display the last modification time of a file, which
is not supported on OpenBSD, FreeBSD and Darwin. Instead use stat(1).

Tested on OpenBSD.

Similar to #1321: The '-c' option for 'head' is non-portable (not in
POSIX).

[clean up] Replacing some literals with constants in zstd_compress_literals.c

Merging facebook/dev into bimbashrestha/dev

Fix 2 bugs in dictionary loading

* Silently skip dictionaries less than 8 bytes, unless using `ZSTD_dct_fullDict`.
  This changes the compressor, which silently skips dictionaries <= 8 bytes.
* Allow repcodes that are equal to the dictionary content size, since it is in bounds.

* Adds the fuzzer
* Adds an additional `InputType` for the fuzzer

I ran the fuzzer for about 10 minutes and it found 2 bugs:

* Catches the original bug without any help
* Catches an additional bug with 8-byte dictionaries

Disable reloading dictionary when there is no known srcSize

Add CMake flag for linking programs dynamically

Gating named pipe support on windows

Added "--exclude-compressed" flag feature
