nfs_diskless: Fix handling of nfsuserd case for NFSv4
Commit 8b9775912cbc added support for an NFSv4 mounted
root file system, but only if the NFSv4 configuration
used id numbers in the strings.
This patch adds support for the case where the NFSv4
configuration uses name<-->id mappings via nfsuserd(8)
by priming the mapping cache with just enough entries
so that it works until the nfsuserd(8) is running.
They are listed in nfs_prime_userd[] in
sys/fs/nfs/nfs_commonsubs.c.
The entries in nfs_prime_userd[] are also wired into
the kernel's cache for name<-->id mappings when nfsuserd(8)
starts up. This is necessary, since an upcall to the
nfsuserd(8) daemon for a mapping when looking up the
path to the passwd/group database files (/etc) will
hang the system, due to a vnode lock being held on

sh: Increase default history size to POSIX mandated minimum of 128
The default history size in bin/sh is currently 100 however POSIX.1-2024
mandates that a default greater than or equal to 128 shall be used,
therefore this increases the default history size in /bin/sh to 128.

manuals: System message vs kernel message
Wordsmith mentions throughout the manual of syslog and dmesg, to clearly
differentiate them in an externally consisteny way, increasing operator
onboarding speed and elegance.
The daemon that handles general system messages, syslog, describes them
as "system messages", and "messages" is the standard filename. Rewrite
syslog related manual titles to align search results with this, and hier
entries to align the index. Use care to maintain keywords and not add
extra lines. Newsyslog trades "maintain" with "rotate" for visibility.

pkgbase: remove incorrect clang shlib requires
The FreeBSD-clang package contains a 32-bit shared object at
/usr/lib/clang/19/lib/freebsd/libclang_rt.asan-i386.so
This is expected, since clang uses this object when compiling for i386
targets with asan enabled.
What is not expected is that the FreeBSD-clang package currently depends
on 32-bit libc packages due to pkg's shared library analysis, making it
impossible to install pkgbase on x86_64 without any lib32 packages.
This commit leverages a new pkg feature implemented in [1], but could
be landed before a pkg version including that feature is released
without any ill effects. Unknown keys in package manifests are ignored.
