Printing a string slice ("&str") in Rust would print until the
terminating \0; but that is incorrect because a slice has a length.
This fixes &str printing, and arranges to preserve the type name when
slicing a slice, so that printing a slice of an "&str" works as well.
This is PR rust/22236.

In gdbserver, target descriptions need to be initialized by calling
init_target_desc. Because i386_create_target_description is shared with

This changes read_memory_robust to return a std::vector, allowing the
removal of free_memory_read_result_vector and associated cleanups.
This patch also changes the functions it touches to be a bit more

read_memory_robust could have leaked in some situations.
This patch is based on my earlier series to remove some MI cleanups.
