If a recipe can do stable version upgrade and the stable parts of the version
is seperated by '.', then it can inherit this bbclass.

By default, the stable parts number is 2, which means the following upgrades
are stable version upgrades:
x.y.z -> x.y.z+1
x.y.z+1 -> x.y.z+1.zz
x.y.z+1.zz -> x.y.z+2

Recipes that have different stable version parts can also inherit this bbclass
and set STABLE_VERSION_PARTS. For example, systemd sets this variable to "1".

For recipes whose stable version part is not separated by '.', they should not
inherit this bbclass and intead set UPSTREAM_STABLE_RELEASE_REGEX themselves.
For example, openssh's stable part is separted by 'p' and should not inherit
this bbclass.
