Branch: next
Switch to the the CMake-ified Seastar
This change allows Scylla to be compiled against the `master` branch of
Seastar.
The necessary changes:
- Add `-Wno-error` to prevent a Seastar warning from terminating the
build
- The new Seastar build system generates the pkg-config files (for
example, `seastar.pc`) at configure time, so we don't need to invoke
Ninja to generate them
- The `-march` argument is no longer inherited from Seastar (correctly),
so it needs to be provided independently
- Define `SEASTAR_TESTING_MAIN` so that the definition of an entry
point is included for all unit test compilation units
- Independently link Scylla against Seastar's compiled copy of fmt in
its build directory
- All test files use the (now public) Seastar testing headers
- Add some missing Seastar headers to source files

This commit adds statistics to row_locker class. Metrics are
independendly counted for all lock types: row<->partition and
exclusive<->shared.
Metrics gathered:
- total acquisitions
- operations that wait on the lock
- histogram of the time spent on waiting on this type of lock

This ensures we respect the write timeout set by the client when
applying base writes, in case a writes takes too long to acquire the
row lock for the read-before-write phase of a materialized view
update.

This is a unit test for the row_locker facility. It tests various
combination of shared and exclusive locks on rows and on partitions,
some should succeed immediately and some should block.
This tests the row_locker's API only, it does not use or test anything
in Materialized Views.
