[legacy] Fix buffer overflow in v0.2 and v0.4 raw literals decompression
...
Extends the fix in PR#1722 to v0.2 and v0.4. These aren't built into
zstd by default, and v0.5 onward are not affected.
I only add the `srcSize > BLOCKSIZE` check to v0.4 because the comments
say that it must hold, but the equivalent comment isn't present in v0.2.
Credit to OSS-Fuzz.

[fuzz] Improve fuzzer build script and docs
...
* Remove the `make libFuzzer` target since it is broken and obsoleted
by `CC=clang CXX=clang++ ./fuzz.py build all --enable-fuzzer`. The
new `-fsanitize=fuzzer` is much better because it works with MSAN
by default.
* Improve the `./fuzz.py gen` command by making the input type explicit
when creating a new target.
* Update the `README` for `--enable-fuzzer`.
Fixes #1727 .

fixed very minor inefficiency (nbSeq==127)
...
The nbSeq "short" format (1-byte)
is compatible with any value < 128.
However, the code would cautiously only accept values < 127.
This is not an error, because the general 2-bytes format
is compatible with small values < 128.
Hence the inefficiency never triggered any warning.
Spotted by Intel's Smita Kumar.

Fix the build on GCC 4.x after 812e8f2a1
...
The ancient GCC 4.x doesn't understand the "optimize" attribute until 4.4.
Fix the build on platforms with GCC 4.x < 4.4 by limiting the DONT_VECTORIZE
definition to GCC 5 and greater.
Noticed and patch proposed by Warner Losh <imp@FreeBSD.org >.
