From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: feat: Add data parameter to ProcessSingleton
Subject: feat: Add data transfer mechanism to requestSingleInstanceLock flow
This patch adds an additional_data parameter to the constructor of
ProcessSingleton, so that the second instance can send additional
data over to the first instance while requesting the ProcessSingleton
lock.
This patch adds code that allows for the second instance to send
additional data to the first instance, and for the first instance
to send additional data back to the second instance, during the
app.requestSingleInstanceLock call.
On the Electron side, we then expose an extra parameter to the
app.requestSingleInstanceLock API so that users can pass in a JSON
object for the second instance to send to the first instance.
Firstly, this patch adds an additional_data parameter
to the constructor of ProcessSingleton, so that the second instance
can send additional data over to the first instance
while requesting the ProcessSingleton lock.
Then, we add additional processing to the second-instance event, both
so the first instance can receive additional data from the second
instance, but also so the second instance can send back additional
data to the first instance if needed.
