tools/squashfs4: add new tool for squashfs4 images
squashfs tool is finally reborn and correctly maintained. Introduce the new version as a replacement for squasfs4kit as it was a fork and also abandoned. Add additional patch to add the missing feature present in squashfskit4 but still missing on this new project. Backport each required patch that fix compilation error on macos.

Subject: [PATCH] Only use available CPUs
|
||||
|
||||
Not all online CPUs may be available for the current process,
|
||||
especially when CPU affinity is involved. In such cases too many
|
||||
threads will be created, which will then compete unnecessarily
|
||||
for CPU time.
|
||||
|
||||
Use sched_getaffinity() to determine the correct number of threads
|
||||
to create.

Subject: [PATCH] Don't use sigwaitinfo()/sigtimedwait() if not supported
|
||||
|
||||
If sigwaitinfo() and sigtimedwait() are not supported,
|
||||
use sigwait() instead.
|
||||
|
||||
This will disable the queue/caches dump if ^\ (SIGQUIT)
|
||||
is hit twice within a second.
|
||||
|
||||
But the queue/caches dump is still available if SIGHUP
|
||||
is sent to the program.
|
||||
|
||||
Currently this check is applied to MAC OS X. FreeBSD and
|
||||
NetBSD appear to have these functions.

Subject: [PATCH] Move sysinfo.h into the linux-only section, should fix build

on MacOS.
|

|

All compilers set `__linux__`, but `linux` may not be defined, and usage
|

was mixed. Use `__linux__` everywhere instead.

macos

Currently the include of sys/sysctl.h is guarded and done only for

FreeBSD system. Remove this to fix compilation error on macos following

the same pattern done in mksquashfs.c
