6a78e9df77 Detect (probably inadvertent) attempts to inherit reactive contexts across processes
Example (we want this to fail):

library(shiny)
library(future)
plan(multicore)

r <- reactiveVal(TRUE)
isolate({
  f <- future({
    r()
  })
  value(f)
})

27cae0065e Fix bug where req(cancelOutput=TRUE) would leave things grey
This was introduced by some changes to shinyapp.js that were necessary
before async outputs and sync outputs were held/flushed together. Now
that async/sync outputs are held/flushed together, these changes are
not necessary and removing them fixes the problem.

The test app is in shiny-examples/205-async-req. I also moved a test
app from manualtests/async/download.R to shiny-examples/204-async-download.

6a1f9677a5 Support async downloadHandler content functions
If a downloadHandler content function returns a promise (or future)
then Shiny will wait for the promise to resolve before serving up
the file download.

2602dc15b0 Changes to flush cycle to support async
- Moved (in|de)crementBusyCount calls out of Context and into Observer
- decrementBusyCount is (effectively) deferred for async observers until
  the async operation is complete
- invalidateLater didn't force(session), almost certainly was buggy
- invalidateLater, reactiveTimer, and manageInputs all now use a new
  session$cycleStartAction, which delays their effect until observers
  (including async ones) are done executing
