cb5eba8e20 add zcat symlink support, suggested by @wtarreau 
added some test
also updated relevant doc

+ fixed a mistake in `lz4` symlink support :
  lz4 utility doesn't remove source files by default (like zstd, but unlike gzip).
  The symlink must behave the same.

05dffe43a7 Fixed Btree update 
ZSTD_updateTree() expected to be followed by a Bt match finder, which would update zc->nextToUpdate.
With the new optimal match finder, it's not necessarily the case : a match might be found during repcode or hash3, and stops there because it reaches sufficient_len, without even entering the binary tree.
Previous policy was to nonetheless update zc->nextToUpdate, but the current position would not be inserted, creating "holes" in the btree, aka positions that will no longer be searched.
Now, when current position is not inserted, zc->nextToUpdate is not update, expecting ZSTD_updateTree() to fill the tree later on.

Solution selected is that ZSTD_updateTree() takes care of properly setting zc->nextToUpdate,
so that it no longer depends on a future function to do this job.

It took time to get there, as the issue started with a memory sanitizer error.
The pb would have been easier to spot with a proper `assert()`.
So this patch add a few of them.

Additionnally, I discovered that `make test` does not enable `assert()` during CLI tests.
This patch enables them.

Unfortunately, these `assert()` triggered other (unrelated) bugs during CLI tests, mostly within zstdmt.
So this patch also fixes them.

- Changed packed structure for gcc memory access : memory sanitizer would complain that a read "might" reach out-of-bound position on the ground that the `union` is larger than the type accessed.
  Now, to avoid this issue, each type is independent.
- ZSTD_CCtxParams_setParameter() : @return provides the value of parameter, clamped/fixed appropriately.
- ZSTDMT : changed constant name to ZSTDMT_JOBSIZE_MIN
- ZSTDMT : multithreading is automatically disabled when srcSize <= ZSTDMT_JOBSIZE_MIN, since only one thread will be used in this case (saves memory and runtime).
- ZSTDMT : nbThreads is automatically clamped on setting the value.

5eb749e734 ZSTDMT_compress() creates a single frame 
The new strategy involves cutting frame at block level.
The result is a single frame, preserving ZSTD_getDecompressedSize()

As a consequence, bench can now make a full round-trip,
since the result is compatible with ZSTD_decompress().

This strategy will not make it possible to decode the frame with multiple threads
since the exact cut between independent blocks is not known.
MT decoding needs further discussions.

0d07ec0c0c Enable build on FreeBSD ports (includes DragonFly BSD) 
Zstd has been introduced to FreeBSD ports
(http://www.freshports.org/archivers/zstd/) which DragonFly BSD also
uses.  FreeBSD and DragonFly use the install targets (albeit modified in
some cases) so they must be added to the associated Makefile filters.
