This fixes the gcc9 build of rtld-elf32 on amd64, which needed an
implementation of udivmoddi4.
rtld-elf uses certain functions normally found in libc, and so it
includes certain files from libc in its own build. It has two
mechanisms to include files from libc: one that rebuilds source files in
the rtld-elf environment, and one that extracts object files from a
purpose-built no-SSP PIC archive.
In addition to libc functions, rtld-elf may need to link functions
normally found in libcompiler_rt (formerly libgcc). Now, add an ability
to rebuild libcompiler_rt source files in the rtld-elf environment. We
don't yet have a need for an object file extraction mechanism.
libcompiler_rt could also supply udivdi3 and umoddi3, but leave them
alone for now.

ar cr is an update of an archive, not a creation of a new one. During
incremental builds (e.g. with meta mode) the archive was not getting
cleaned, and so could retain now-deleted objects from previous builds.
Now, delete the archive before creating/updating it.

This partially lifts a restriction imposed by r191639 ("Prevent a superuser
inside a jail from modifying the dedicated root cpuset of that jail") that's
perhaps beneficial after r192895 ("Add hierarchical jails."). Jails still
cannot modify their own cpuset, but they can modify child jails' roots to
further restrict them or widen them back to the modifying jails' own mask.
As a side effect of this, the system root may once again widen the mask of
jails as long as they're still using a subset of the parent jails' mask.
This was previously prevented by the fact that cpuset_getroot of a root set
will return that root, rather than the root's parent -- cpuset_modify uses
cpuset_getroot since it was introduced in r327895, previously it was just
validating against set->cs_parent which allowed the system root to widen
jail masks.

When exporting a variable we correctly check all the preconditions that
could make setenv(3) fail. Checking the setenv(3) return value seems
redundant, but given that login(1) is critical, it doesn't hurt to have
a post-check.
This change is based on the "Principles of Secure Coding" course by
Matthew Bishop, PhD., which specifically discusses this code in FreeBSD.

These Mini-Box LCDs are using Microchip components and sub-licensed product
IDs. Whilst here, update the constant names and descriptions for the products
to use the names listed on the manufacturer's website rather than vague ones.
The picoLCD 4x20 is named that on the manufacturer's website so prefer that
name, even though linux-usb.org lists it with the numbers reversed as one might
expect.

rtsock code was build around the assumption that each rtentry record
in the system radix tree is a ready-to-use sockaddr. This assumptions
turned out to be not quite true:
* masks have their length tweaked, so we have rtsock_fix_netmask() hack
* IPv6 addresses have their scope embedded, so we have another explicit
deembedding hack.
Change the code to decouple rtentry internals from rtsock code using
newly-created rtentry accessors. This will allow to eventually eliminate
both of the hacks and change rtentry dst/mask format.

The SRAT may contain multiple distinct entries that together describe a
contiguous region of physical memory. In this case we were not
coalescing the corresponding entries in the memory affinity table, which
led to fragmented phys_avail[] entries. Since r338431 the vm_phys_segs[]
entries derived from phys_avail[] will be coalesced, resulting in a
situation where vm_phys_segs[] entries do not have a covering
phys_avail[] entry. vm_page_startup() will not add such segments to the
physical memory allocator, leaving them unused.

This caused us to write to the low half of the feature word twice, once with
the high bits and once with the low bits. Common legacy device implementations
seem to be fairly lenient about being able to write to the feature bits
multiple times, but Arm's models use a stricter implementation that will ignore
the second write. This fixes using vtnet(4) on those models.

Fix error in extent_try_coalesce_impl(), which could cause abort
to happen when trying to coalesce extents backwards. The error could
happen because of how extent_before_get() function works. This function
gets address of previous extent, by subtracting page size from current
extent address. If current extent is located at PAGE_SIZE offset, this
address resolved to 0x0000. An assertion in rtree_leaf_elm_lookup
then caused the running program to abort.
This problem was discovered when trying to build world on 32-bit
machines with ASLR and PIE enabled. The problem was encountered
on armv7 and i386 machines, but most likely other 32-bit
architectures are affected as well.
While this patch fixes one problem with buildworld on 32-bit platforms
with ASLR, the build still fails, however it happens much later
and due to lack of memory.
The change is aligned with accepted fix in the upstream Jemalloc
repository (https://github.com/jemalloc/jemalloc/pull/1973).
As it doesn't apply on top of Jemalloc tree, its updated version
was eventually merged: https://github.com/jemalloc/jemalloc/pull/2003
