We have installed kernel debug data under /usr/lib/debug/ for some time
now, so the suggestion to set WITHOUT_KERNEL_SYMBOLS for small root
partitions is no longer valid.
Also call them "debug symbol files" rather than just "symbol files",
since they contain much more than just symbols. The kernel also
includes (some) symbols, regardless of the setting of this knob.

6cafdee71d2b adapted the pkgbase build for 1.17, but broke Cirrus-CI's
use of PKG_FORMAT=tar (the quarterly package set still has pkg 1.16).
Because of this I disabled the pkgbase build and test in 2bfba2a04b05.
Now, check `pkg --version` and use the old logic for < 1.17.
To be reverted once we no longer encounter pkg 1.16 in Cirrus-CI (i.e.,
via GCP cloud images) to avoid keeping this extra complexity around.

Stop using temporal page table with 1:1 mapping of low 1G populated over
the whole VA. Use 1:1 mapping of low 4G temporarily installed in the
normal kernel page table.
The features are:
- now there is one less step for startup asm to perform
- the startup code still needs to be at lower 1G because CPU starts in
real mode. But everything else can be located anywhere in low 4G
because it is accessed by non-paged 32bit protected mode. Note that
kernel page table root page is at low 4G, as well as the kernel itself.
- the page table pages can be allocated by normal allocator, there is
no need to carve them from the phys_avail segments at very early time.
The allocation of the page for startup code still requires some magic.
Pages are freed after APs are ignited.
- la57 startup for APs is less tricky, we directly load the final page
table and do not need to tweak the paging mode.

The upper vnode reference to the lower vnode is the only reference that

during the VOP call, upper vnode might become unlocked and reclaimed,
