Add a parameterized AMP argument type which can serialize and unserialize 0 or more of a specified type

New submission from exarkun <[email protected]>:

There's presently no argument type which supports several integers, or several strings.  Strangely, there is an argument type for several dictionaries (`AmpList`).  Supporting some other types would be nice.

This might look something like `ListOf(String())`.  `AmpList` might be expressed in terms of this as `ListOf(Dict())`, although there is presently no `Dict` argument type.

I'm most immediately motivated to have such an argument type for #1784: code for that ticket smashes a list of strings together in one process and then splits it up again in another process.  Supremely gross.  I'm certain there are many other similar use cases, though.
