We currently don't clean up the system_distributed.view_build_status
table after removed nodes. This can cause false-positive check for
whether view update generation is needed for streaming.
The proper fix is to clean up this table, but that will be more
involved, it even when done, it might not be immediate. So until then
and to be on the safe side, filter out entries belonging to unknown
hosts from said table.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
Move replica-oriented classes to the replica namespace. The main
classes moved are ::database, ::keyspace, and ::table, but a few
ancillary classes are also moved. There are certainly classes that
should be moved but aren't (like distributed_loader) but we have
to start somewhere.
References are adjusted treewide. In many cases, it is obvious that
a call site should not access the replica (but the data_dictionary
instead), but that is left for separate work.
scylla-gdb.py is adjusted to look for both the new and old names.
This just causes unneeded and slower recompliations. Instead replace
with forward declarations, or includes of smaller headers that were
incidentally brought in by the one removed. The .cc files that really
need it gain the include, but they are few.
Ref #1.
Closes#8403
Checking if view update path should be used for sstables
is going to be reused in row level repair code,
so relevant functions are moved to a separate header.
