* changes:
adbd: avoid compiling more code in the daemon.
adb: don't run all of the tests again over TCP in coverage.
adbd: respect ADB_TRACE on host adbd.
adb: mark kMaxProcessNameLength as constexpr.
They take forever, and we're only really interested in the transport
related code, so test that more directly.
Test: ./coverage/gen_coverage.sh
