aarzilli 454491ce86 service,logflags: log all RPC messages 
We occasionally receive bug reports from users of VSCode-go and GoLand.
GoLand has its own way of capturing the packet exchange between itself
and delve but VSCode-go (supposedly) doesn't.
So far this hasn't been a problem since all bug reports were obvious
bugs on the plugin or easy to reproduce without VSCode-go, but it might
be helpful in the future to have a way to log the packet exchange
between dlv and a frontend.

This commit adds a --log-output option to enable logging of all rpc
messages and changes service/rpccommon accordingly.

dlv attach

Attach to running process and begin debugging.

Synopsis

Attach to an already running process and begin debugging it.
