This commits allows `heim_object_t` as a type and causes the generated code to use the `heim_retain()` and `heim_release()` functions for copying and releasing values of such types. Also, now one can have more than one decoration per-type.

/*
|
|
* XXX We need to move all module state out of globals and into a struct that
|
|
* we pass around when parsing and compiling a module, and also that we keep on
|
|
* a linked list of parsed modules.
|
|
*
|
|
* This is needed to:
|
|
*
|
|
* - implement IMPORTS correctly, because we need to know the type of a symbol
|
|
* in order to emit an extern declaration of it
|
|
* - implement value parsing
|
|
* - implement an ASN.1 library that does value parsing
|
|
*
|
|
* Value parsing, in particular, would be fantastic. We could then have
|
|
* options in hxtool(1) to load arbitrary ASN.1 modules and then parse SAN
|
|
* values given in ASN.1 value syntax on the command-line or in files. Eat
|
|
* your heart out OpenSSL if we do this!
|
|
*
|
|
* As well we'll need a `-I' option to the compiler so it knows where to find
|
|
* modules to IMPORT FROM.
