This release adds Ruby 2.7, 3.0, and 3.1 support.
This also fixes breakage in urcu v0.11.4, v0.12.3, and v0.13.1.
While urcu v0.12.4 and v0.13.2 were released 2022-08-18,
old versions will continue to be in distros for a while
(and urcu v0.11.x won't be updated).
There are also several updates ported from the Perl version.
7 changes since v2.1.0 in 2018:
memalign: perform rcu_read_unlock on ENOMEM
workaround breakage from urcu v0.11.4
constify arg for totals_add_rcu
support Ruby 3.0.x
disable HeapPageBody count test for Ruby 3.1
quiet uninitialized and unused variable warnings
various doc updates
Available via RubyGems and https://80x24.org/mwrap/

We must not forget to release RCU read locks even if the
process will probably die, soon, due to ENOMEM.
I noticed this while working on the Perl5/XS port.
