Exceptions breakpoints get set once at the beginning of the session after the
"initialized" event is sent back to the debugger. The ClearBreakpoint is just
for cleanup after all is said and done.

No. It doesn't actually share anything from BreakpointBase. You would think it
would, but it doesn't.

it keeps the code much cleaner. Some of the LLVM JSON calls return an
"llvm::json::Object *" when fetching a value for a key which can be NULL. The
primary reason for these functions it to keep the code clean and simple. I
prefer to keep these overloads.

+std::vector<std::string> GetStrings(const llvm::json::Object *obj,
+ llvm::StringRef key);
+
----------------
Need to keep as is because as noted in the description, numbers and booleans
will be converted to strings. This is in case you specify arguments for your
program as:
```
"args": [ 123, "hello", true ]
```

I am gonna leave this one as is because we must pass a "const char *" the API
that is called inside the body of this method:
```
lldb::SBBreakpoint lldb::SBTarget::BreakpointCreateByLocation(const char
*file, uint32_t line);
```

Causes build errors when I tried switching.

Doesn't work with std::string and we need the std::string to back the string
content.
================
Comment at: tools/lldb-vscode/VSCode.h:83
+ std::vector<std::string> exit_commands;
+ std::vector<std::string> stop_commands;
+ lldb::tid_t focus_tid;

These are usually empty. No need to use SmallVector and force storage when we
don't need it.

This is iterating through an array of classes and check if the member variable,
which is a std::string is equal. Leaving as std::string

Leaving as std::string as we need to guarantee null termination

I will add an anonymous namespace around all local functions.
