This encapsulates what our multi-client IPC servers typically do on
startup:
1. Create a Core::LocalServer
2. Take over a listening socket file descriptor from SystemServer
3. Set up an accept handler for incoming connections
IPC::MultiServer does all this for you! All you have to do is provide
the relevant client connection type as a template argument.
These ones all manage their storage internally, whereas the WebContent
and ImageDecoder ones require the caller to manage their lifetime. This
distinction is not obvious to the user without looking through the code,
so an API that makes this clearer would be nice.
Everyone used this hook in the same way: immediately accept() on the
socket and then do something with the newly accepted fd.
This patch simplifies the hook by having LocalServer do the accepting
automatically.
This functionality, while neat, isn't really something you need enabled
all the time. Let's make it opt-in instead. Pass MakeInspectable::Yes
to the Core::EventLoop constructor if you want your program to become
inspectable.
This service daemon will act as an intermediary between the Inspector
program and the inspectable programs it wants to inspect.
Programs can make themselves available for inspection by connecting
to /tmp/portal/inspectables using the Core::EventLoop RPC protocol.
