runtime: just do file/line lookup in C, move Func to Go
In order to port stack backtraces to Go, we need the ability to look up
file/line information for PC values without allocating memory. This
patch moves the handling of Func from C code to Go code, and simplifies
the C code to just look up function/file/line/entry information for a PC.
