75bc289911 Fix Makefile Variable Concatenation Order 
Previously, this construct would add `-O3` onto the end of the compiler flags
variable, **after** `MOREFLAGS`, which meant that it was impossible to over-
ride. This commit fixes this order and should otherwise be a no-op.

39a32f40c9 fixed default rule for lib/Makefile 
default rule is `lib-release`

`lib-release` wasn't working : it was just skipped.

Removing `lib-release` from the list of .PHONY targets fixes it.

Same for `lib-mt`.

082755bd3f do not install zbuff.h 
this API is deprecated, for a loong time now,
all related symbols will be removed in a future version (likely v1.5.0)
and the header file `zbuff.h` doesn't compile from `include/` anyway,
because it needs to be positioned one directory below `zstd.h`.

Also removed `cover.h` from `cmake` installer,
as it should have never been part of this list to begin with.

15561bcf74 Fix pkg-config File Generation Again Again 
Resubmission of #2001. This switches the `sed` invocations to use `-E`,
extended regex syntax, which is better standardized across platforms.
I guess.

Same test plan:

```

cf854f4660 support for verbose make 
A commonly accepted makefile idiom is V=1 or VERBOSE=1
to request the printing of all commands.

This is not "default" though, and must be manually added.

Example :
Before :
```
make libzstd
compiling dynamic library 1.4.5
creating versioned links

make libzstd V=1
compiling dynamic library 1.4.5
creating versioned links
```

After :
```
make libzstd
compiling dynamic library 1.4.5
creating versioned links

make libzstd V=1
compiling dynamic library 1.4.5

fa5e01c467 Add Space-Optimized Helper Variable to Lib Makefile 
This diff reorganizes the `lib/Makefile` to extract various settings that a
user would normally invoke together (supposing that they were aware of them)
if they were trying to build the smallest `libzstd` possible. It collects
these settings under a master setting `ZSTD_LIB_MIN_SIZE`.

Also document this new option.

c6ae2e83bc fix libzstd-mt underlinking issue 
fix #2045
When compiling `libzstd` in multithreading mode,
the `libzstd-mt` recipe would not include `-pthread`,
resulting in an underlinked dynamic library.

Added a test on Travis to check that the library is fully linked.

This makes it possible, in some future release,
to build a multi-threaded `libzstd` dynamic library by default
as it would no longer impact the build script of user programs.

ac58c8d720 Fix copyright and license lines 
* All copyright lines now have -2020 instead of -present
* All copyright lines include "Facebook, Inc"
* All licenses are now standardized

The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.

The copyright and license of `divsufsort.{h,c}` is not changed.

73737231b9 Allow Manual Overriding of pkg-config Lib and Include Dirs 
When the `PCLIBDIR` or `PCINCDIR` is non-empty (either because we succeeded
in removing the prefix, or because it was manually set), we don't need to
perform the check. This lets us trust users who go to the trouble of setting
a manual override, rather than still blindly failing the make.

They'll still be prefixed with `${prefix}/` / `${exec_prefix}/` in the
pkg-config file though.

74bd76c3ff In pkg-config File, Derive Lib and Include Dir from Prefix at Use-Time 
Addresses #1794. Instead of deriving the lib dir and include dir at
build-time, let's do it like everyone else does at pkg-config run-time.

This has the disadvantage that we can no longer override LIBDIR and
INCLUDEDIR in the Makefile and have that reflected in the .pc file.

812e8f2a16 perf improvements for zstd decode (#1668) 
* perf improvements for zstd decode

tldr: 7.5% average decode speedup on silesia corpus at compression levels 1-3 (sandy bridge)

Background: while investigating zstd perf differences between clang and gcc I noticed that even though gcc is vectorizing the loop in in wildcopy, it was not being done as well as could be done by hand.  The sites where wildcopy is invoked have an interesting distribution of lengths to be copied.  The loop trip count is rarely above 1, yet long copies are common enough to make their performance important.The code in zstd_decompress.c to invoke wildcopy handles the latter well but the gcc autovectorizer introduces a needlessly expensive startup check for vectorization.

See how GCC autovectorizes the loop here:
https://godbolt.org/z/apr0x0

Here is the code after this diff has been applied: (left hand side is the good one, right is with vectorizer on)
After: https://godbolt.org/z/OwO4F8

Note that autovectorization still does not do a good job on the optimized version, so it's turned off\
 via attribute and flag.  I found that neither attribute nor command-line flag were entirely successful in turning off vectorization, which is why there were both.

    silesia benchmark data - second triad of each file is with the original code:

* makefile changed to only pass -fno-tree-vectorize to gcc

* <Replace this line with a title. Use 1 line only, 67 chars or less>

Don't add "no-tree-vectorize" attribute on clang (which defines __GNUC__)

* fix for warning/error with subtraction of void* pointers

* fix c90 conformance issue - ISO C90 forbids mixed declarations and code

* Fix assert for negative diff, only when there is no overlap

* fix overflow revealed in fuzzing tests

* tweak for small speed increase

9a0643b633 lib/Makefile: create include directory before headers installation 
Make sure that $(INCLUDEDIR) exists before copying the headers there.
Otherwise, the contest of header files is copied over
$(DESTDIR)$(INCLUDEDIR), making it a regular file.

While at it, remove $(DESTDIR)$(INCLUDEDIR) from the list of directories
to create in the install-pc target. The install-pc target does not need
this directory.

2d4d31c18a removed gcc compilation flag -Wbad-function-cast 
It makes it more difficult to directly cast the result of a function,
requiring to store the result in an intermediate variable.
It does not necessarily help readability,
and this restriction can be difficult to overcome in some constructions,
like some macros.

Zstd has been introduced to FreeBSD ports

uses.  FreeBSD and DragonFly use the install targets (albeit modified in
some cases) so they must be added to the associated Makefile filters.
