Luigi Semenzato d8abf55c1b metrics client: add basic sanity check for numeric arguments 
"atoi" and "atod" don't do any conversions or error checks, they
just return 0 on error.  They should be illegal.

Luigi Semenzato 3268422240 Add generic "event of interest" enumerated histogram. 
This change aims to simplify the addition of events we may
want to track in the field, more specifically hard-to-reproduce
bugs.  Before this change, this requires creating a new histogram
and registering it via histograms.xml, which is not in the Chrome OS
repositories.  With this change, a new event just requires claiming
an event name (such as ModemManagerCommandSendFailure) in
metrics_library.cc, and running "metrics_client -v <event name>"
or calling SendCrosEventToUMA(event_name).

I can make up a bug for this.  Or not.
