Variable name "args" can be confused with "*args"

[Pennycook]

Several functions in CBI take a parameter called args, intended to mean the "arguments" list that appears in a compilation database entry.

This can easily be confused with *args, and should be changed to something like argv: list[str] across all impacted functions.

I think the association is that args is usually used like (*args, **kwargs) and unpacked, so I mentally assume multiple things will be passed into the function like so:

def func(*args):
    for arg in args: ...

where I can use the function like func(a, b, c, d), whereas this current style I can only use it via func((a, b, c, d)).

Hey @Pennycook, if you could assign me, I'll open a PR for review.

Thanks, @itsjayway! Please note that both @laserkelvin and I will be out of the office after today, so apologies in advance if it takes us a few weeks to get around to reviewing your PR.
