5ff2e55e00 bin/pkill: Fix {pgrep,pkill}-j_test.sh
The POSIX sh case statement does not allow for pattern matching using the
regex + qualifier so this case statement never matches. Instead just check
for a string starting with a digit followed by any character.

While touching these files also fix various shellcheck warnings.

`kyua -v parallelism=4 test` failed before, succeeds now.

90b5fc9583 lib/libc/tests/rpc: Correctly set timeout
The rpc_control() API does not accept the CLCR_SET_RPCB_TIMEOUT command,
it only accepts RPC_SVC_CONNMAXREC_GET/RPC_SVC_CONNMAXREC_SET, so it was
not doing anything.
Instead of incorrectly calling this API, use clnt_create_timed() instead.

I noticed this because the test was timing out after 120s in the CheriBSD CI.

0ff1014944 Update Subversion to 1.14.1 LTS. See contrib/subversion/CHANGES for a
summary of changes, or for a more thorough overview:

https://subversion.apache.org/docs/release-notes/1.14

NOTE 1: There is no need to dump and reload repositories, and the
working copy format is still the same as Subversion 1.8 through 1.13.

NOTE 2: The upstream release also contains a fix for a security issue in
mod_dav_svn (CVE-2020-17525), but since we do not build or use any
Apache modules, it is not an issue for the FreeBSD base system.

c975494ad7 build: turn off FMTREE by default to prepare for removal
nmtree is derived from fmtree, and has been the default mtree(8) since
6adfbbbf16, a little over a year after its introduction.

fmtree has not seen any substantial work since then, except for build
fixes and runtime issues that were diagnosed in nmtree and backported
because this was still in the tree.

Turn it off by default.

f540cb27a2 mount_nullfs: rename a local variable
The "source" variable was introduced in r26072, probably as the
traditional counterpart to "target".  But the "source"/"target" names
suggest the opposite of their actual meaning.  With ln, for example, the
source is the real file and the target is the newly created link.  In
mount_nullfs the meaning is the opposite: the target is the existing
file system and the source is the newly created mountpoint.  Better to
use "target"/"mountpoint" terminology, which matches the man page.

8563de2f27 Fix bug 253158 - Panic: snapacct_ufs2: bad block - mksnap_ffs(8) crash
The panic reported in 253158 arises because the /mnt/.snap/.factory
snapshot allocated the last block in the filesystem. The snapshot
code allocates the last block in the filesystem as a way of setting
its length to be the size of the filesystem. Part of taking a
snapshot is to remove all the earlier snapshots from the image of
the newest snapshot so that newer snapshots will not claim the blocks
of the earlier snapshots. The panic occurs when the new snapshot
finds that both it and an earlier snapshot claim the same block.

The fix is to set the size of the snapshot to be one block after
the last block in the filesystem. This block can never be allocated
since it is not a valid block in the filesystem. This extra block
is used as a place to store the initial list of blocks that the
snapshot has already copied and is used to avoid a deadlock in and
speed up the ffs_copyonwrite() function.

ede40b0675 ffs softdep: remove will_direnter argument of softdep_prelink()
Originally this was done in 8a1509e442 to forcibly cover cases
where a hole in the directory could be created by extending into
indirect block, since dependency of writing out indirect block is not
tracked.  This results in excessive amount of fsyncing the directories,
where all creation of new entry forced fsync before it.  This is not needed,
it is enough to fsync when IN_NEEDSYNC is set, and VOP_VPUT_PAIR() provides
the required hook to only perform required syncing.

The series of changes culminating in this commit puts the performance of
metadata-intensive loads back to that before 8a1509e442.

06f2918ab8 ufs_direnter: directory truncation does not need special case for rename
In ufs_rename case, tdvp is locked from the place where ufs_direnter()
is done till VOP_VPUT_PAIR(), which means that we no longer need to specially
handle rename in ufs_direnter().  Truncation, if possible, is done in the
same way in ffs_vput_pair() both for rename and other VOPs calling
ufs_direnter().  Remove isrename argument and set IN_ENDOFF if
ufs_direnter() succeeded and directory needs truncation.

In ffs_vput_pair(), stop verifying the condition that directory needs
truncation when IN_ENDOFF is set, instead assert that the condition is
true.

74a3652f83 ufs_direnter: move directory truncation to ffs_vput_pair().
VOP_VPUT_PAIR() provides the hook to do the truncation right before
unlock, which is required since truncation might need to fsync(), which
itself might unlock the directory vnode.

Set new flag IN_ENDOFF which indicates that i_endoff is valid and should
be checked against inode size. Excessive size is chomped, but this
operation is advisory and failure to truncate should not result in the
failure of the main VOP.

30bfb2fa0f ffs_vput_pair(): try harder to recover from the vnode reclaim
In particular, if unlock_vp is false, save vp's inode number and
generation. If ffs_inotovp() can re-create the vnode with the same
number and generation after we finished with handling dvp, then we most
likely raced with unmount, and were able to restore atomicity of open.
We use FFSV_REPLACE_DOOMED there, to drop the old vnode.

This additional recovery is not strictly required, but it improves the
quality of the implementation.

49c117c193 Add VOP_VPUT_PAIR() with trivial default implementation.
The VOP is intended to be used in situations where VFS has two
referenced locked vnodes, typically a directory vnode dvp and a vnode
vp that is linked from the directory, and at least dvp is vput(9)ed.
The child vnode can be also vput-ed, but optionally left referenced and
locked.

There, at least UFS may need to do some actions with dvp which cannot be
done while vp is also locked, so its lock might be dropped temporary.
For instance, in some cases UFS needs to sync dvp to avoid filesystem
state that is currently not handled by either kernel nor fsck. Having
such VOP provides the neccessary context for filesystem which can do
correct locking and handle potential reclamation of vp after relock.

Trivial implementation does vput(dvp) and optionally vput(vp).
