Some exported symbols should stay hidden ?

[kapouer]

When building a shared libllhttp library (using cmake), the list of exported symbols (attached)
contains a lot of llhttp__internal__c* symbols.
I suppose these should not be exported, i.e. be protected or with visiblity attribute set.

llparse probably needs to support this too.
