The traditional ptimer behaviour includes a collection of weird edge case behaviours. In 2016 we improved the ptimer implementation to fix these and generally make the behaviour more flexible, with ptimers opting in to the new behaviour by passing an appropriate set of policy flags to ptimer_init(). For backwards-compatibility, we defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old weird behaviour. This turns out to be a poor choice of name, because people writing new devices which use ptimers are misled into thinking that the default is probably a sensible choice of flags, when in fact it is almost always not what you want. Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that new devices should not be using it. The code-change part of this commit was produced by sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT) with the exception of a test name string change in tests/unit/ptimer-test.c which was added manually.
