30c7698970 optimize ZSTDMT_compress() memory usage
does no longer allocate temporary buffers
when there is enough room in dstBuffer to decompress directly there.
(previous method would skip that for 1st chunk only).

Also : fix ZSTD_compressBound() for small srcSize

3f75d52527 Changed ZSTD_compressBound()
required so that if Total = A+B
compressBound(Total) <= compressBound(A) + compressBound(B)
under condition of a minimum size for A and B

Will help for ZSTDMT_compress() memory allocation

274f59919d Changed memory strategy to __packed for gcc
Method 1 __packed is always as good or better than memcpy().
But it's not portable, as it depends on compiler extension.

For gcc, __pakced directive works fine.
Furthermore, gcc has serious performance issues with memcpy() on ARM 32 bits.
See #620
