c13f81905a Fix #1861: Restrict overlapLog Parameter When Not Built With Multithreading 
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.

60205fec02 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.

5d5c895b18 fix initCStream_advanced() for fast strategies 
Compression ratio of fast strategies (levels 1 & 2)
was seriously reduced, due to accidental disabling of Literals compression.

Credit to @QrczakMK, which perfectly described the issue, and implementation details,
making the fix straightforward.

Example : initCStream with level 1 on synthetic sample P50 :
Before : 5,273,976 bytes
After  : 3,154,678 bytes
ZSTD_compress (for comparison) : 3,154,550

Fix #1787.

To follow : refactor the test which was supposed to catch this issue (and failed)
