mount_procfs(8): Document the format of the region descriptor
lines contained in the 'map' and 'maps' special files.

branches: 1.38.8;
- options NAMECACHE_ENTER_REVERSE is no more.

- Partially sort the list of per-vnode namecache entries by using a TAILQ.
Put the real name to the head, and put dot and dotdot to the tail so that
cache_lookup_reverse() doesn't have to consider them.

Bump date for previous.

Remove the filesystem tracing feature

This is a legacy interface from 4.4BSD, and it was
introduced to overcome shortcomings of ptrace(2) at that time, which are
no longer relevant (performance). Today /proc/#/ctl offers a narrow
subset of ptrace(2) commands and is not applicable for modern
applications use beyond simplistic tracing scenarios.

This removal will simplify kernel internals. Users will still be able to
use all the other /proc files.

This change won't affect other procfs files neither Linux compat
features within mount_procfs(8). /proc/#/ctl isn't available on Linux.

Remove:
- /proc/#/ctl from mount_procfs(8)
- P_FSTRACE note from the documentation of ps(1)
- /proc/#/ctl and filesystem tracing documentation from mount_procfs(8)
- KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9)
- source code file miscfs/procfs/procfs_ctl.c
- PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h
- KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h
- PSL_FSTRACE (0x00010000) from sys/sys/proc.h
- P_FSTRACE (0x00010000) from sys/sys/sysctl.h

Reduce code complexity after removal of this functionality.

Update TODO.ptrace accordingly: remove two entries about /proc tracing.

Do not keep legacy notes as comments in the headers about removed
PSL_FSTRACE / P_FSTRACE, as this interface had little number of users
(close or equal to zero).

Proposed on tech-kern@.

All filesystem tracing utility users are encouraged to switch to ptrace(2).

whooops, bump date also

proc/#/exe is now exposed for all mounts, move it away from linux-only

Bump date for previous.

Add "cwd" and "root" symlinks to each process's directory. The cwd
link points to the process's current working directory, and the root
link points to the process's root directory. What else would you
expect?

For directories that are out of reach (caller is in a chroot, target
process is in a different chroot, etc), the links point to "/"
instead.

Fix PR#3617 and PR#3205: call realpath to convert mount points and paths to
device nodes into absolute paths before using them.

Move UCB-licensed code from 4-clause to 3-clause licence.

.Nm does not need a dummy argument ("") before punctuation or

New sentence, new line. By Robert Elz with minimal fixes.

Add descriptions of the "self" symbolic link and the "maps" pseudo file.
Also note the kernel option that is required in order to get pathnames
with file backed entries in the "maps" pseudo file.
