Audit of the paths that drop or refuse something. registerEvent() dropped an eleventh
handler and a second one for the same name without a word: the name now gets the new
handler, an eleventh name and a call without a name or a function print an error. A
device that cannot be announced printed two lines, one without its id; it prints one.
setLogLevel() above ALEX2ESP_LOG_MAX prints an error that names the build flag.
"the handler sent no answer" is an error for a handler of onDirective() only: a 1.x
handler may answer from a later loop(), its silence is a line at DEBUG.
getDevice() returning nullptr and printMemoryInfo() are documented; keywords.txt has
the 2.0 names and loses three that were removed.
basicLight: static RAM 30,520 B, flash 333,989 B (+600); ALEX2ESP_LOG_MAX=0 30,496 /
327,953, =3 30,520 / 334,477; five examples, log0 and log3 build with 0 warnings.
Host tests: 135 (dispatch 11 -> 16).
