8157a4c3cc Fix dictionary loading bug causing an MSAN failure 
Offset rep codes must be in the range `[1, dictSize)`.
Fix dictionary loading to reject `0` as a offset rep code.

064a143520 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`.

e474aa55b4 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`.

0012332ce0 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.
