[legacy] Fix ZSTDv0*_decodeSequence()
...
* Version <= 0.5 could read beyond the end of `dumps`, which points into
the input buffer.
* Check the validity of `dumps` before using it, if it is out of bounds
return garbage values. There is no return code for this function.
* Introduce `MEM_readLE24()` for simplicity, since I don't want to trust
that there is an extra byte after `dumps`.

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 stack buffer overrun when weightTotal == 0
...
If `weightTotal == 0`, then `BIT_highbit32(weightTotal)` is
undefined behavior in the case that it calls `__builtin_clz()`.
If `tableLog == HUF_TABLELOG_ABSOLUTEMAX` then we will access one
byte beyond the end of the buffer.
