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.
The database, keyspace, and table classes represent the replica-only
part of the objects after which they are named. Reading from a table
doesn't give you the full data, just the replica's view, and it is not
consistent since reconciliation is applied on the coordinator.
As a first step in acknowledging this, move the related files to
a replica/ subdirectory.
We were not consistent about using '#include "foo.hh"' instead of
'#include <foo.hh>' for scylla's own headers. This patch fixes that
inconsistency and, to enforce it, changes the build to use -iquote
instead of -I to find those headers.

Use std::function instead of a template parameter. Likely doesn't gain
anyting, because the template was always instantiated with the same type
(the result of std::bind() with the same signatures), but still good practice.
std::function was used instead of noncopyable_function because
sharded::map_reduce0() copies the input function.

Many headers don't really need to include database.hh, the include can
be replaced by forward declarations and/or including the actually needed
headers directly. Some headers don't need this include at all.
Each header was verified to be compilable on its own after the change,
by including it into an empty `.cc` file and compiling it. `.cc` files
that used to get `database.hh` through headers that no longer include it
were changed to include it themselves.
This adds a stub implementation to the commit log metrics.
The calls return the currect value type with a stub value.
After this patch the following url will be available:
/commitlog/metrics/completed_tasks
/commitlog/metrics/pending_tasks
/commitlog/metrics/total_commit_log_size

This adds the implementation of the commitlog API.
Current implementation contains:
/commitlog/segments/active
That returns a list of the active file names, and
/commitlog/segments/archiving
Which always return an empty list as we archiving is not supported at
the moment
The doc file is under:
