vty: sub-divide talloc contexts and include them in talloc report
The VTY code makes so many allocations that a full report is
simply too long to provide any useful information. So we sub-divide
it in multiple contexts, and report only one level deep at SIGURS1.
We also introduce SIGUSR2 for the full detailed VTY report.
