We don't have any upgrade_to_v2() left in production code, so no need to
keep testing it. Removing it from this test paves the way for removing
it for good (not in this series).
In most files it was unused. We should move these to the patch which
moved out the last interesting reader from mutation_reader.hh (and added
the corresponding new header include) but its probably not worth the
effort.
Some other files still relied on mutation_reader.hh to provide reader
concurrency semaphore and some other misc reader related definitions.
This method used to be a static one in
boost/flat_mutation_reader_test.cc. Turns out it is useful for other
tests based on the mutation source test suite, so move it into the
header of the latter to make it accessible.
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
There are 4 flavours of mutation source tests that are all ran
sequentially -- plain, reversed and upgrade/downgrade ones that
check v1<->v2 conversions.
This patch splits them all into individual calls so that some
tests may want to have dedicated cases for each. "By default" they
are all run as they were.

The random mutation generator currently generates data and tombstones
with random timestamps selected from a pre-determined range. This
results in mutations where tombstones often cover each other and data.
There is nothing wrong with this, as this is how real data is too.
However for certain tests this is problematic, as compacting the
mutations will result in a different mutations. To cater for these users
too, introduce a `generate_uncompactable` option. When set to `yes`, the
generated mutations will be uncompactable, i.e. no tombstone will cover
lower-level tombstones and no tombstone will cover data. The mutations
will not change after compacted.
Move another small subset of headers to test/
with the same goals:
- preserve bisectability
- make the revision history traceable after a move
Update dependent files.
