rin | ld(4): Convert blkno argument for sc_dump() to daddr_t
PR kern/59153
(1) For backends that accept 64-bit block address, i.e.,
nvme(4), virtio(4), aac(4), iop(4), and mainbus(usermode/4),
this should enable to dump beyond 2Gi blocks.
(2) sdmmc(4) backend allows to dump up to the last block.
(3) For other backends, block address is handled as `int`.
Some of them may support blocks up to 4Gi, but I do not have
enough time to examine datasheets. So, continue to reject >2Gi
blocks as before.
XXX
This is KABI change, and cannot be pulled up into netbsd-{10,9}.
XXX
Compile-test only (for amd64/ALL) due to lack of large SSDs ;)
Thanks mlelstv@ for discussion and careful review!!

mlelstv | While ld(4) is MP safe, many backends are not.
Add a flag for backends that are MP safe. Take KERNEL_LOCK when calling
into a backend that doesn't have the flag set. Do the same for the
discard routine.
Fixes PR 52462.

Entropy-pool implementation move and cleanup.
1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.
ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

While ld(4) is MP safe, many backends are not.
Add a flag for backends that are MP safe. Take KERNEL_LOCK when calling
into a backend that doesn't have the flag set. Do the same for the
discard routine.
Fixes PR 52462.
Defer sdmmc discard operations to the sdmmc task queue. Fixes a panic
introduced by ld.c r1.102.
validate length for discard operation and split operation when byte length
doesn't fit into 'int'.
make the sc_discard interface for the ld backend asynchronous and
signal completion through new callback lddiscardend. Use a standard
struct buf to pass disk address and range instead of two off_t values.
make lddiscard synchronous again. This is a requirement of the current
ffs discard code.
Initialize error also in the case where len=0, which just succeeds.
while here, assert that the len is indeed non-negative. this is already
confirmed by sys_fdiscard, but let's be sure.
reported by: GCC, but with different compile flags
