gsapi_set_param improvements.

Allow for a 'parsed' param type; this leverages the functions in
gsparaml.c to parse an input string into a param list, coping
with dictionaries and arrays.

We update those functions to improve behaviour on more exotically
formed numbers ("- 0.3e-10" etc), on 'tricksy' inputs (e.g.
"<< /Foo (>>) >>" etc) and to cope without relying on whitespace
(e.g. "<</Foo/Bar/Baz[1 0]/Fizz<1234>/Bang(A)>>" etc).

Update pl_implementation set_param entrypoint so that the language
interface itself is based upon param lists, rather than typed
params.

Update both implementations of gsapi_set_params so that if
we are too early in the setup process stuff goes into the list
and is held until we have devices/languages to pass it to. Also
add a flag to allow for 'more to come' so that we can effectively
set multiple params at once.
