Retry property set failures
SystemProperties.set() is not a reliable method, for reasons that are
unknown. This change adds the utility class SystemPropertySetter with
a static setWithRetry() method. There are two overloads: one which
takes the maximum number of retries and the delay between retries, and
one which uses new system constants.
Clients should use the new method if set() failures are fatal.
Note that some failures cannot be recovered by retrying. SELinux
denials are one example. However, such errors are almost always
coding errors and not operational errors, and so should be discovered
during development.
The code, along with the constants, is ported from
PropertyInvalidatedCache, where it has been use successfully for
several years.
The new method is used in AudioService and in PIC.
The new methods are not system APIs and do not have CTS tests.
