Add transport_opt() watchdog_config

To make the number of watchdogs sent before the transitions REOPEN ->
OKAY and OKAY -> SUSPECT configurable. Using anything other then the
default config is non-standard and should only be used for test.
Minor spec fix
Rework stats to avoid concurrent read and write

Counters read by diameter:service_info(SvcName, transport) can be
selected at the same time as the diameter_stats server is folding them
into another key, possibly resulting in inaccurate values. Have
diameter_stats select from the server process to avoid this and add
diameter_stats:sum/1 to sum values from all contributors on a given
term.
Rework watchdog suite to remove most timing dependencies

Count watchdog messages instead when this is an alternative.
