squashfs-tools: bump to version 4.4 

All patches are not needed anymore. squashfs-tools has implemented them in
one way or another.

Converted to download release tarballs. This should work better to get
notified of a newer release.

Also adds support for ZSTD compression:

From ac6268e843c43286eebff2a1052182c2393cdb2e Mon Sep 17 00:00:00 2001
From: Roy Li <rongqing.li@windriver.com>

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

Subject: [PATCH] mksquashfs/unsquashfs: fix compilation with glibc 2.25+
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From glibc 2.25 release notes:
https://sourceware.org/ml/libc-alpha/2017-02/msg00079.html
"* The inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated.
This means that in a future release, the macros “major”, “minor”, and
“makedev” will only be available from <sys/sysmacros.h>."
See glibc bug https://sourceware.org/bugzilla/show_bug.cgi?id=19239 .
