perf symbols: Add interface to read DSO image data
Adding following interface for DSO object to allow
reading of DSO image data:
dso__data_fd
- opens DSO and returns file descriptor
Binary types are used to locate/open DSO in following order:
DSO_BINARY_TYPE__BUILD_ID_CACHE
DSO_BINARY_TYPE__SYSTEM_PATH_DSO
In other word we first try to open DSO build-id path,
and if that fails we try to open DSO system path.
dso__data_read_offset
- reads DSO data from specified offset
dso__data_read_addr
- reads DSO data from specified address/map.
