Use unique_xmalloc_ptr for read_string
This changes read_string's "buffer" out-parameter to be a
unique_xmalloc_ptr, then updates the users. This allows for the
removal of some cleanups.
I chose unique_xmalloc_ptr rather than byte_vector here due to the way
Guile unwinding seems to work.
Tested by the buildbot.
