Since fdb987bebd it is not possible anymore to use inp_next
iterator for bound, but unconnected sockets. This applies
to TCP listening sockets. Therefore the metioned commit broke
tcpsso on listening sockets if the -i option was not used.
Fix this by iterating through all endpoints instead of only
through the bound, but unconnected ones.

In particular, don't reserve resources added by drivers via other
means (e.g. acpi_bus_alloc_gas which calls bus_alloc_resource
right after adding the resource).
The intention of reserved resources is to ensure that a resource range
that a bus driver knows is assigned to a device is reserved by the
system even if no driver is attached to the device. This prevents
other "wildcard" resource requests from conflicting with these
resources. For ACPI, the only resources the bus driver knows about
for unattached devices are the resources returned from _CRS. All of
these resources are already reserved now via acpi_reserve_resources
called from acpi_probe_children.
As such, remove the logic from acpi_set_resource to try to reserve
resources when they are set. This permits RF_SHAREABLE to work with
acpi_bus_alloc_gas without requiring hacks like the current one for
CPU device resources in acpi_set_resource.

memdesc_alloc_ext_mbufs constructs a chain of external (M_EXT or
M_EXTPG) mbufs backed by a data buffer described by a memory
descriptor.
Since memory descriptors are not an actual buffer just a description
of a buffer, the caller is required to supply a couple of helper
routines to manage allocation of the raw mbufs and associating them
with a reference to the underlying buffer.

- Fail if source block is smaller than destination. We can only

- Fail if we do not have full znode range lock. In that case grow

to know when cloning needs to grow the block size unlike write.
- Fail of we tried to resize, but failed. There are many reasons
for it to fail that we can not predict at this level, so be ready
for them. Unlike write, that may proceed after growth failure,
block cloning can't and must return error.
This fixes assertion inside dmu_brt_clone() when it sees different
number of blocks held in destination than it got block pointers.

This function decompresses to two buffers and then compares them to
check whether the (opaque) decompression process filled the whole
buffer. Previously it began with lbuf uninitialized and lbuf2 filled
with pseudorandom data. This neither guarantees that any bytes not
written by the compressor would be different, nor seems incredibly
sound otherwise!
After these changes, instead of filling one buffer with generated
pseudorandom data we overwrite each buffer with completely different
data. This should remove the possibility of low-probability failures,
as well as make the process simpler and cheaper.

The standard is somewhat unclear, but on the balance, I believe that the
phrase “the rest of the input line” should be interpreted to mean the
rest of the input line including the terminating newline if and only if
there is one. This means the current implementation is incorrect on two
points:
- First, it suppresses the previous line's newline in the '1' case.
- Second, it unconditionally emits a newline at the end of the output
for non-empty input, even if the input did not end with a newline.
Resolve this by rewriting the main loop. Instead of special-casing the
first line and then assuming that every line ends with a newline, we
remember how each line ends and emit that either at the beginning of
the next line or at the end of the file except in the one case ('+')
where the standard explicitly says not to.
While here, try to reduce diff to upstream a little and update their
RCS tag to reflect the fact that while we've diverged significantly
from them, we've incorporated all their changes. Remove the useless
second RCS tag.
We also update the tests to account for the change in interpretation
of the '1' case and add a test case for unterminated input.

2. On both arm and arm64, the definitions of these symbols are guarded
