Mark Salyzyn 71919f4f5d liblogcat: measure performance
Existing dummy benchmark converted to a single-pass benchmark.

Add support for ">[filename]" interpretation in liblogcat, helpful to
provide more consistent benchmark results when sending output to
/dev/null.

NB: results are not consistent as there is a roundtrip to logd
    service, but they are indicative of better performance for
    liblogcat.
