This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
At the moment it is a bit hard to distinguish which of the functions we are using belong to ctags. To make more explicit what we need from ctags, wrap all ctags-related code and access ctags only using this layer. The interface from tm_ctags_wrappers.h can serve as a base for proper ctags interface if ctags becomes a library.
