Add support for array and pointer typedefs

[Schamper]

While the current syntax parser is quite restricting and due a rewrite, this will add support for a long time outstanding annoyance where the following syntax would not behave as expected:

typedef char uuid_t[16];

Previously, this would simply add a type alias for "char" as the literal string "uuid_t[16]". With this PR, this finally behaves as expected and allows you to typedef UUID character arrays!

Not sure if we also want to support multiple typedefs on a single line, for example:

typedef char uuid_t[16], UUID[16];

If not, then it LGTM!

Edit: nevermind about the multiple typedefs on single line, i see that it's not part of this change :)
