liblog: Add private interfaces for buffer size properties
Add private function __android_logger_get_buffer_size() to read
properties and compose the default buffer size. This interface
complements the existing android_looger_get_size() which returns
the logd setting which can differ at runtime. For use in logd
and dumpstate. Side effect is we also add the private functions
__android_logger_property_get_bool() and
__android_logger_valid_buffer_size() for reuse in logd.
Test: gTest liblog-unit-test, logd-unit-tests and logcat-unit-tests in
combination with commit 'logd: Use private interfaces for
buffer size properties'
