This is a modified version of a previous patch that was reverted: https://reviews.llvm.org/D119797
This version only waits for the process to stop when using "launchCommands" or "attachCommands"...
...and doesn't play with the async mode when doing normal launch/attach.
We discovered that when using "launchCommands" or "attachCommands" that there was an issue where these commands were not being run synchronously. There were further problems in this case where we would get thread events for the process that was just launched or attached before the IDE was ready, which is after "configurationDone" was sent to lldb-vscode.
This fix introduces the ability to wait for the process to stop after "launchCommands" or "attachCommands" are run to ensure that we have a stopped process point that is ready for the debug session to proceed. We spin up the thread that listens for process events before we start the launch or attach, but we don't want stop events being delivered through the DAP protocol until the "configurationDone" packet is received. We now always ignore the stop event with a stop ID of 1, which is the first stop. All normal launch and attach scenarios use the synchronous mode, and "launchCommands and "attachCommands" run an array of LLDB commands in async mode.
This should make our launch with "launchCommands" and attach with "attachCommands" avoid a race condition when the process is being launched or attached.

We discovered that when using "launchCommands" or "attachCommands" that there was an issue where these commands were not being run synchronously. There were further problems in this case where we would get thread events for the process that was just launched or attached before the IDE was ready, which is after "configurationDone" was sent to lldb-vscode.
This fix introduces the ability to wait for the process to stop after the run or attach to ensure that we have a stopped process at the entry point that is ready for the debug session to proceed. This also allows us to run the normal launch or attach without needing to play with the async flag the debugger. We spin up the thread that listens for process events before we start the launch or attach, but we stop the first eStateStopped (with stop ID of zero) event from being delivered through the DAP protocol because the "configurationDone" request handler will deliver it manually as the IDE expects a stop after configuration done. The request_configurationDone will also only deliver the stop packet if the "stopOnEntry" is False in the launch configuration.
Also added a new "timeout" to the launch and attach launch configuration arguments that can be set and defaults to 30 seconds. Since we now poll to detect when the process is stopped, we need a timeout that can be changed in case certain workflows take longer that 30 seconds to attach. If the process is not stopped by the timeout, an error will be retured for the launch or attach.
Added a flag to the vscode.py protocol classes that detects and ensures that no "stopped" events are sent prior to "configurationDone" has been sent and will raise an error if it does happen.
This should make our launching and attaching more reliable and avoid some deadlocks that were being seen (https://reviews.llvm.org/D119548).

A few users recently were trying to set environment values when using lldb-vscode and were unsure of the format of the "env" launch configuration setting. Clarify the exact format as when users add the "env" launch config setting, they can see this help string in the IDE.

This diff ass postRunCommands, which are the counterpart of the preRunCommands. TThey will be executed right after the target is launched or attached correctly, which means that the targets can assume that the target is running.

The tests seem to be timing out in all linux bots. Need further analysis.
Revert "run in terminal"
This reverts commit de6caf871be79dc7549aebe4e4fb57d52f6ed202.
When lldb cannot find source file thus IDE renders a disassembly view, add syntax highlighting for constants, registers and final line comments for better debugging experience.
The original plain disassembly view looks like:
{F12401687}
An ideal view is like the screenshot attached.
{F12401515}
In this diff, the mimeType is a kind of media type for formatting the content in the response to a source request. Elements in the disassembly view, like constants, registers and final line comments are colored for highlighting.
A built-in support in the VSCode IDE for syntax highlighting will identify the which mimeType to apply and render the disassembly view as expected.

Summary:
Running `vsce package` to package lldb-vscode as an installable .vsix file errors with:
```
ERROR Invalid publisher name 'llvm.org'. Expected the identifier of a publisher, not its human-friendly name.
```
This patch fixes the publisher name and bumps a required dependency so that `vsce package` succeeds.

Summary:
Currently loading core files on lldb-vscode is broken because there's a check in the attach workflow that asserts that the PID is valid, which of course fails for this case.
Hence, I'm adding a "coreFile" argument for the attach request, which does the work correctly.
I don't know how to test it effectively so that it runs on the buildbots and the debugger can in fact makes sense of it. Anyway, the change has been relatively simple.

Summary:
If no custom launching is used, lldb-vscode launches a program with an empty environment by default. In some scenarios, the user might want to simply use the same environment as the IDE to have a set of working environment variables (e.g. PATH wouldn't be empty). In fact, most DAPs in VSCode have this behavior by default. In other cases the user definitely needs to set their custom environment, which is already supported. To make the first case easier for the user (e.g. not having to copy the PATH to the launch.json every time they want to debug simple programs that rely on PATH), a new option is now offered. inheritEnvironment will launch the program copying its own environment, and it's just a boolean flag.

This commit fixes an issue with lldb-vscode failing to run programs that
use different architecture/platform than the "empty" in the target.
Original implementation was creating a default target without specifying
the target architecture, platform or program, and then would set
executable file through SBLaunchInfo, assuming that this would update
architecture and platform accordingly. However this wasn't really
happening, and architecture and platform would remain at whatever values
were in the "empty" target. The simple solution is to create target
already for a desired architecture and platform.
Function request_attach is updated in a similar fashion.
This commit also adds new JSON properties to "launch" and "attach"
packets to allow user to override desired platform and architecture.
This might be especially important for cases where information in ELF is
not enough to derive those values correctly.
New code has a behavior similar to LLDB MI [1], where typically IDE would
specify target file with -file-exec-and-symbols, and then only do -exec-run
command that would launch the process. In lldb-vscode those two actions are
merged into one request_launch function. Similarly in the interpreter
session, user would first do "file" command, then "process launch"

Windows can't use standard i/o system calls such as read and write
to work with sockets, it instead needs to use the specific send
and recv calls. This complicates matters for the debug adapter,
since it needs to be able to work in both server mode where it
communicates over a socket, as well as non-server mode where it
communicates via stdin and stdout. To abstract this out, I've
introduced a class IOStream which hides all these details and
exposes a read/write interface that does the right on each
platform.
