squashfs-tools: upgrade to commit f95864afe883

The master branch's current tip commit as of this writing is [1], see the
squashfs-tool's repo at [0].

Because of commits [2]-[4] which are included in the master branch three
corresponding patches are dropped as they are not needed anymore. The single
remaining patch was rebased on top of [1] to apply cleanly.

Commits [5] & [6] introduced interesting features, namely zstd support and
reproducibility of created SquashFS images. They are reflected in two new
PACKAGECONFIG options now, but only the latter ("reproducible") is appended to
the default options as OE-core does not contain a recipe to build zstd at the
moment (a working zstd recipe can be found e.g. in meta-rauc, see [7]).

-Subject: [PATCH] mksquashfs.c:  get inline functions work with both gnu11 and gnu89
-
-Upstream-Status: Pending
-
-After gcc upgraded to gcc5, and if the codes is compiled without optimization(-O0),
-and the below error will happen:
-
-| mksquashfs.o: In function `create_inode':
-| git/squashfs-tools/mksquashfs.c:897: undefined reference to `get_inode_no'
-| git/squashfs-tools/mksquashfs.c:960: undefined reference to `get_parent_no'
-| git/squashfs-tools/mksquashfs.c:983: undefined reference to `get_parent_no'
-| mksquashfs.o: In function `reader_read_process':
-| git/squashfs-tools/mksquashfs.c:2132: undefined reference to `is_fragment'
-| mksquashfs.o: In function `reader_read_file':
-| git/squashfs-tools/mksquashfs.c:2228: undefined reference to `is_fragment'
-| mksquashfs.o: In function `dir_scan':
-| git/squashfs-tools/mksquashfs.c:3101: undefined reference to `create_dir_entry'
-
-gcc5 defaults to -std=gnu11 instead of -std=gnu89, and it requires that exactly one C
-source file has the callable copy of the inline function. Consider the following
-program:
-
-  inline int
-  foo (void)
-  {
-    return 42;
-  }
-
-  int
-  main (void)
-  {
-    return foo ();
-  }
-
-The program above will not link with the C99 inline semantics, because no out-of-line
-function foo is generated. To fix this, either mark the function foo as static, or
-add the following declaration:
-  static inline int foo (void);
-
-more information refer to: https://gcc.gnu.org/gcc-5/porting_to.html;
-
-but the use of "extern inline" will lead to the compilation issue if gcc is not
-gcc5, as the commit in oe-core d0af30c92fde [alsa-lib: Change function type to
-"static __inline__"]
-    "extern __inline__ function()" is the inlined version that
-    can be used in this compilation unit, but there will be another
-    definition of this function somewhere, so compiler will not emit
-    any code for the function body. This causes problem in -O0,
-    where functions are never inlined, the function call is preserved,
-    but linker can't find the symbol, thus the error happens.
-
-so replace "inline" with "static inline" to make it work with both gnu11 and gnu89
