Update list of filesystems that support ID-mapped mounts.

Newer kernels in principle support the creation of ID-mapped mounts for
filesystems mountable in non-initial user namespaces. Currently, no such
filesystem has been ported to support this though. But we should
nonetheless update the conditions.

In order to ID-map a mount it must not have any writers. If the mount
has writers and the caller tries to ID-map the mount EBUSY will be

This adds very basic information about the notification pipe that have
been added into Linux 5.8.
There is some description about the interface at:
https://www.kernel.org/doc/html/latest/core-api/watch_queue.html
(I think that there is at least on bug in that page, since the
notification pipe has to be opened with O_NOTIFICATION_PIPE which is
defined to O_EXCL not O_TMPFILE)
The ENOPKG error should be clear from this header (see
watch_queue_init() at the end):

This differs from what was being done until now. Before, we were
updating the timestamp with the date of the release, but that's
unnecessarily unprecise. With this, we have the actual date of
when the last change was committed.

A valid file descriptor will be non-negative, i.e., 0 <= fd <= INT_MAX.
When all of the bits of a valid file descriptor are flipped, the result
is a negative value: ~0 = -1, ~1 = -2, ..., ~INT_MAX = INT_MIN. If all
of these bits are flipped again, then the file descriptor is recovered.
Negating the file descriptor does not quite achieve this, because there
will be no change for fd 0. (Likewise, negating INT_MIN would not cause
any change in value, but it is never a valid file descriptor.)

Change "supported only since" to "support was added in".
Previously, this said, "MAP_POPULATE is supported for private mappings only
since Linux 2.6.23." This could be parsed as "MAP_POPULATE is supported
for private mappings only [not shared mappings] since Linux 2.6.23."
Someone (a native English speaker) tried to tell me this.
Change to "Support for MAP_POPULATE in conjunction with private mappings
was added in Linux 2.6.23." This is unambiguous, and "support was
added" is more common in other man pages.
There are more instances of "supported only since", but they seem
clearer. I could send a separate patch for them if desired.

It was straight after a note that they are nonstandard functions,
which already tells the user that if portability is in mind, they
shouldn't be used, so this recommendation adds nothing in that
sense.
Also, there's a note that timelocal() should _never_ be used, due
to mktime() being identical and in the POSIX standard (it is also
in C99), so this note would also add nothing in that sense.
So the only uses not covered by those other notes are non-portable
uses of timegm(3). In that scenario, it is an excellent function.

Userfaultfd minor fault mode is supported starting from Linux 5.13.
This commit adds a description of the new mode, as well as the new ioctl
used to resolve such faults. The two go hand-in-hand: one can't resolve
a minor fault without continue, and continue can't be used to resolve
any other kind of fault.
v1->v2:
- Some spelling / phrasing improvements
v2->v3:
- Improved line wrapping in man2/ioctl_userfaultfd.2
v3->v4:
- Rebased onto http://www.alejandro-colomar.es/src/alx/linux/man-pages/man-pages.git/ main
- Mentioned minor fault shmem support

So, since URI and URL have been used as synonims and it wasn't

have explicitly avoided URL, and now use URI as the only term,
which still means what it meant (so now URL is just a synonim for
URI).

fstatat(..., AT_NO_AUTOMOUNT) has had the following history in Linux:
v2.6.37-7314-g6f45b65672c8
add AT_NO_AUTOMOUNT and fstatat honors it
v3.1-rc7-68-gb6c8069d3577
ignore AT_NO_AUTOMOUNT since default operation now less eagerly mounts
v4.10-11255-ga528d35e8bfc
adds statx which reinstated 2.6.38 behavior for fstatat (not released)
v4.11-rc7-14-gdeccf497d804
adjust fstatat so that AT_NO_AUTOMOUNT always specified (to statx)
* man2/stat.2:
Adjust AT_NO_AUTOMOUNT description for fstatat.2 as per the above,
to indicate AT_NO_AUTOMOUNT should be avoided with fstatat() since
it's ignored since 3.1 and implied since 4.11.
Don't mention commit v4.13-9318-g42f461482178 as it was reverted,
and moot anyway since we can't adjust AT_NO_AUTOMOUNT since 3.1.
* man2/statx.2:
Mention that stat(), lstat(), and fstatat() imply AT_NO_AUTOMOUNT.

With only the default debug level documented, neither the possible
range of the debug levels nor their purpose was apparent. This made it
hard to use debug levels. So we add a short description of them.

It was a residue from old code, before the FTM subsection.

This function doesn't encrypt. It encodes, which is different.
But I used the word obfuscate, which is the same that glibc uses,
and it is very clear, I think.
