As discussed in the vAttachWait patch (https://reviews.llvm.org/D93895), I've
implemented a jAttachWait packet with supports two additional parameters
(polling interval and polling duration) when attaching to a process by name and
waiting for it to appear.
`jAttachWait` send a json packet of the format: `{"process_name": string,
"include-existing: bool, "waitfor-interval-usec": microseconds,
waitfor-duration-sec: seconds}` where `waitfor-interval-usec` and
`waitfor-duration-sec` are only sent if specified by the user.
For this first implementation I decided to add the arguments as additional
flags to `process attach`, but I can change this if you think that's not a good
idea.
I was also wondering if this could/should be expanded in a more general
`jAttach` packet, where the packet contents would specify if lldb-server should
wait or not, what are your thoughts on that?
Lastly, this current implementation has a bug I couldn't figure out, where if
we're sending l an error response, `lldb` loses connection to `lldb-server`
(this happens even if the first thing I do in the `handle_jAttachWait` function
is return an error) and, also, CTRL+C from `lldb` doesn't interrupt
`lldb-server`. If anyone know why this might be happening, I'd be glad to hear
it.
