Optimization for tiny x in cos and sin
Subset of FreeBSD commit
4339c67c485f0b1f7699863fc29f6c06862d1dde:
Moved the optimization for tiny x from __kernel_{cos,sin}[f](x) to
{cos_sin}[f](x) so that x doesn't need to be reclassified in the
"kernel" functions to determine if it is tiny (it still needs to be
reclassified in the cosine case for other reasons that will go away).

- Cluster requests when sending them to backends
- Return a better error code in a lot of cases.
- Allow bulkget to return row by row instead of column by column (as per
RFC3416)
- Better SNMPv1 mapping as per RFC3584
- Allow registration of overlapping regions.
- Stricter OID comparison.
- We loose write support. Previous write support didn't guarantee
atomicity, wasn't persistent across restarts and didn't implement
anything useful. This can be added later if it's missed.
- This is quite a bit slower, but this should clear up once the current
mps.c and mib.c code gets pushed out. Other tricks could help speed
things up, but I don't want to resort to extra tricks if it's not needed.

Cleanup the scattered OBJ_txt2obj() calls and move them into
x509_init_oid() to initalize all necessary OID objects at start.

Properly handle read-only clusters in m_pullup(9).
If the first mbuf of a chain in m_pullup is a cluster, check if the
cluster is read-only (shared or an external buffer). If so, don't
touch it and create a new mbuf for the pullup data.
This restores original 4.4BSD m_pullup, that not only returned
contiguous mbuf data of the specified length, but also converted
read-only clusters into writeable memory. The latter feature was
lost during some refactoring.

Improve how quirks are handled on sdhc(4)-compatible drivers. So far
we have passed a modified version of the contents in the capabilities
register if we wanted to override what sdhc(4) would otherwise read.
Unfortunately there's a second capabilities register that we did not
yet take into consideration, which is why to disable DDR50 support we
created a quirk flag in the softc. The sdhc(4) ACPI nodes have a way
to mask and set bits in both of the capabilities register, which is a
flexible approach to solving that issue and using that for our sdhc(4)
drivers even improves readability.

return EIO, not ENXIO, when the interface underneath ifq_deq_sleep dies.
this is consistent with other drivers when they report their
underlying device being detached.

plic: Fix cpuid handling
Make `cpu' signed so that the possible return value -1 from
plic_get_cpuid() gets handled correctly in the (cpu < 0) condition.
This prevents plic_attach() from updating sc_contexts[] out of bounds.
When plic_get_cpuid() returns -1, ignore the entry and continue
processing. The error is not fatal. It is normal that secondary CPUs
are not found when running a non-MULTIPROCESSOR kernel on
a multiprocessor machine.
