libctf: lookups by name and symbol
These functions allow you to look up types given a name in a simple subset of C declarator syntax (no function pointers), to look up the types of variables given a name, and to look up the types of data objects and the type signatures of functions given symbol table offsets. (Despite its name, one function in this commit, ctf_lookup_symbol_name(), is for the internal use of libctf only, and does not appear in any public header files.) libctf/ * ctf-lookup.c (isqualifier): New. (ctf_lookup_by_name): Likewise. (struct ctf_lookup_var_key): Likewise. (ctf_lookup_var): Likewise. (ctf_lookup_variable): Likewise. (ctf_lookup_symbol_name): Likewise. (ctf_lookup_by_symbol): Likewise. (ctf_func_info): Likewise. (ctf_func_args): Likewise. include/ * ctf-api.h (ctf_func_info): New. (ctf_func_args): Likewise. (ctf_lookup_by_symbol): Likewise. (ctf_lookup_by_symbol): Likewise. (ctf_lookup_variable): Likewise.
