PR/58240: Ricardo Branco: Add missing limits

Add linux waitid(2) from GSoC 2023 (Theodore Preduta)

Add comment on packed attribution for struct linux_epoll_event on amd64.
NFC.

Add epoll(2) from Theodore Preduta as part of GSoC 2023

Always clear FUTEX_PRIVATE_FLAG for Linux processes.  NetBSD-native futexes
exist in different namespace depending on FUTEX_PRIVATE_FLAG.  This appears
not to be the case in Linux, and some futex users will mix private and non-
private ops on the same futex object.  Provide a convenience wrapper that
puts this logic in one place witn a comment explaining why.

While here, move the Linux futex wrapper out of its own file and plop
it in linux_misc.c, which is where it lives in the linux32 module.

LINUX_RLIM_INFINITY doesn't fit into the value range for linux32, so

personality() now interprets its parameter as having
the base personality type in the low byte and
various flags in the upper bytes.  for now just mask off
the flags to make sure the base type is one we accept.
store the current personality in the emuldata so that
we can return the expected value for PER_QUERY.

Split sys_wait4() so that compat code can fiddle with the returned 'status'
and 'rusage' without having to copy data to/from stackgap buffers.
The old split (find_stopped_child) could be removed.
amd64 seems to run netbsd32, linux and linux32 emulations. sparc64 compiles.

PR kern/27184: Have linux_sys_waitpid() call linux_sys_wait4() so the

Add a diagnostic check to see if the one unhandled option (__WNOTHREAD) is

proper statfs emulation...

- add a real linux_sys___sysctl because the mib numbers are different.
  implement only the kernel version getting entries.
- make the signal conversion functions consistent; dest is arg 1.
- make linux_fakedev deal with block and char devices differently.
- add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so
  that they work properly.
- add linux_mmap2 [untested].
- bump kernel to 2.4.18, and make the date be valentine's day :-)
- linux_sys_*stat64 family was totally busted. Fix it.

tested only on i386.

Status:
	gdb, telnet, work
	jdk-1.4.0 extractor works, jdk still coredumps.
