new inotify support GSoC 2023 (Theodore Preduta)

Add memfd_create(2) from GSoC 2023 by Theodore Preduta

- Add compat_linux statx(2) syscall.
- The AT_EMPTY_PATH processing from the modification of
sys/compat/linux/common/linux_file64.c r1.63 has been separated, and made
common to linux_statat(), so that it can be used not only by
linux32_sys_fstatat64() but also by other *statat() variants.

add support COMPAT_LINUX for aarch64

When dealing with an unknown value, set -1, to prevent (harmless)
uninitialized accesses later.

branches: 1.17.10; 1.17.18; 1.17.22;
Add Linux specific fcntl(2) commands. Support F_DUPFD_CLOEXEC.

branches: 1.16.2; 1.16.4; 1.16.10;
Cleanup pipe(2) flags, now that native handle them.

branches: 1.15.2;
Add utimensat(2) for compat linux.

branches: 1.14.34; 1.14.44; 1.14.50;
Remove clause 3 and 4 from TNF licenses

branches: 1.13.2; 1.13.4;
Catch up with descriptor handling changes. See kern_descrip.c revision
1.173 for details.

branches: 1.12.6;
Fix the linux32 emulations of fcntl() locking.
The 64bit linux emulation versions can't be used because the lock structure
alignment and field sizes all differ.
Since there need to be 4 different versions of the linux struct flock, and
amd64 kernel needs 3 of them compiled in, rather than replicating the same
code block twice more, move the body of the code into a few #defines
that can be expanded with the correct types in the linux[32]_sys_fcntl[64]()
functions.
Should fix problems running progams like skype running under linux32
emulation on amd64.

branches: 1.11.46; 1.11.52;
merge ktrace-lwp.

branches: 1.10.2;
First work on COMPAT_LINUX/amd64
Process startup and dynamiclinking work, but processes hang due to
Linux arch_prctl(2) not being really supported yet.

branches: 1.9.10;
implement the locking calls for linux_file64.

Crude first cut at ARMLinux binary compatibility. Successfully runs
"/emul/linux/bin/echo hello, world", dynamically linked.

Enable Mips Linux emulation in header files

branches: 1.6.2; 1.6.4; 1.6.6;
Added Linux compatibility support for powerpc ports

branches: 1.5.8;
Added linux compat support on m68k ports.

Assign my copyright to TNF. Merge with others were appropriate.
Regen syscall files after script change.

Attempt to fix the mess.

Split linux_fcntl.h into i386 and common parts.

Added Linux compat code.
