[PATCH 2/3] ctf-reader: Use smart pointers in create_read_context

["Guillermo E. Martinez" <guillermo.e.martinez@oracle.com>]

	* include/abg-ctf-reader.h (read_context_sptr): New typedef.
	(create_read_context): Use read_context_sptr as return value.
	* src/abg-ctf-reader.cc (create_read_context): Likewise.
	* tools/abidiff.cc (main): Use read_context_sptr.
	* tools/abilint.cc: Likewise.
