Both `jsmntok_t` and `jsmn_parser` are declared as anonymous structures
that are typedeffed to their actual name. This forces all downstream
users of jsmn to always use the typedef name, instead of using e.g.
`struct jsmn_parser`. While this might be considered a matter of taste,
using typedefs only has the technical downside of disallowing forward
declarations. E.g. if a dependent whishes to declare a pointer to
`jsmntok_t` without actually pulling in the "jsmn.h" header, then he is
not able to do so because there is no way in C to provide a forward
declaration for typedefs to anonymous structs.
Fix this by providing names for both `jsmntok_t` and `jsmn_parser`
structures.
