Settings: trampoline persist.logd.logpersistd to logd.logpersistd
- Deal with trampoline, where we read logd.logpersistd and
logd.logpersistd.buffer, write to persist.logd.logpersistd and
persist.logd.logpersistd.buffer and logd.logpersistd*
- Deal with an as designed requirement that empty values do not
automatically trampoline, to properly communicate state.
- check logd.logpersistd.enable boolean for support
