ZDICT_finalizeDictionary() flipped comparison
...
`ZDICT_finalizeDictionary()` had a flipped comparison.
I also allowed `dictBufferCapacity == dictContentSize`.
It might be the case that the user wants to fill the dictionary
completely up, and then let zstd take exactly the space it needs
for the entropy tables.

Fix execSequence wildcopy undefined behavior

execSequence relied on pointer overflow to handle cases where
`sequence.matchLength < 8`. Instead of passing an `size_t` to
wildcopy, pass a `ptrdiff_t`.

Fix decompression buffer overrun
...
Allows an adversary to write up to 3 bytes beyond the end of the buffer.
Occurs if the match overlaps the `extDict` and `currentPrefix`, and the
match length in the `currentPrefix` is less than `MINMATCH`, and
`op-(16-MINMATCH) >= oMatchEnd > op-16`.

Fix compression segfault
...
When the overflow protection kicks in, it makes sure that ip - ctx->base
isn't too large. However, it didn't ensure that saved offsets are
still valid. This change ensures that any valid offsets (<= windowLog)
are still representable after the update.
The bug would shop up on line 1056, when `offset_1 > current + 1`, which
causes an underflow. This in turn, would cause a segfault on line 1063.
The input must necessarily be longer than 1 GB for this issue to occur.
Even then, it only occurs if one of the last 3 matches is larger than
the chain size and block size.
