This library will be used by clang-query. I can imagine LLDB becoming another client of this library, so I think LLVM is a sensible place for it to live. It wraps libedit, and adds tab completion support. The code is loosely based on the line editor bits in LLDB, with a few improvements: - Polymorphism for retrieving the list of tab completions, based on the concept pattern from the new pass manager. - Tab completion doesn't corrupt terminal output if the input covers multiple lines. Unfortunately this can only be done in a truly horrible way, as far as I can tell. But since the alternative is to implement our own line editor (which I don't think LLVM should be in the business of doing, at least for now) I think it may be acceptable. - Includes a fallback for the case where the user doesn't have libedit installed. Note that this uses C stdio, mainly because libedit also uses C stdio.
