Bring in the last version of the optimized memset from the Cortex
Strings library that didn't use the VFP registers. While here clean up
to use the ENTRY/EDIT macros.

These are from the Arm Optimized Routines and don't use the VFP so are

Routing daemons such as bird need to know if they install certain route
 so they can clean it up on startup, as a form of achieving consistent
 state during the crash recovery.
Currently they use combination of routing flags (RTF_PROTO1) to detect
 these routes when interacting via route(4) rtsock protocol.
Netlink protocol has a special "rtm_protocol" field that is filled and
 checked by the route originator. To prepare for the upcoming netlink
 introduction, add ability to record origing to both nexthops and
 nexthop groups via <nhop|nhgrp>_<get|set>_origin() KPI. The actual
 calls will be used in the followup commits.

In 8db2e8fd16c4 ("Remove the secondary_stacks array in arm64 [...]"),
bootstacks was setup to be allocated dynamically.  While this is
generally how x86 does it, it inadvertently shrunk each boot stack from
KSTACK_PAGES pages to a single page.

Resize these back up to the expected size using the kstack_pages
tunable, as we'll need larger stacks with upcoming sanitizer work.

Change RB_INSERT_COLOR and RB_REMOVE_COLOR so that the blocks of code
that are identical except for left and right being exchanged are made
only one block with a variable to indicate left- or right-handedness.

Rename RB macros so that those not intended for external use begin
with an underscore.

Add comments to the balancing code so that another might understand it.

With _RB_DIAGNOSTIC defined, provide an RB_RANK method to compute the
rank of a node in an rb-tree, if the subtree rooted at that node is
rank-balanced, and -1 otherwise.

In rb_test, rewrite a bit to avoid malloc/free and nondeterministic
running times because of randomness. Allocate all the nodes on the
stack, and shuffle a set of keys to get randomness for the testing.

Add a rank-balance check for the completed tree.

This corrects an issue introduced in b4cb3fe0e39a3, where a freshly
allocated `DOS_FS` structure would not be initialized properly before
use in `dos_open`.

In case of FAT32 file systems, this would leave `fs->dirents`
uninitialized and - depending on its content and due to checks in
`parsebs` - prevent mounting the file system successfully.

This particularily impacted the EFI loader, as it was sometimes not
able to read files from a FAT32-formatted EFI partition, including
LoaderEnv (`/efi/freebsd/loader.env`).
