pointer that owns a single Python reference to a PyObject.  This class
acts a bit like unique_ptr, but also a bit like shared_ptr (in that
copies do what you might expect); I considered going solely with
unique_ptr but it seemed quite strange to have a unique_ptr that

Fix inferior memory reading in GDBServer for arm/aarch32

Before this patch, some functions would read the inferior memory with
(*the_target)->read_memory, which returns the raw memory, rather than the
shadowed memory.

This is wrong since these functions do not expect to read a breakpoint
instruction and can lead to invalid behavior.

Use of raw memory in get_next_pcs_read_memory_unsigned_integer for example
could lead to get_next_pc returning an invalid pc.

Here's how this would happen:

In non-stop:

the user issues:

thread 1
step&
thread 2
step&
thread 3
step&

In a similar way as non-stop-fair-events.exp (threads are looping).

GDBServer:

 linux_resume is called
 GDBServer has pending events,
 threads are not resumed and single-step breakpoint for thread 1 not installed.

 linux_wait_1 is called with a pending event on thread 2 at pc A
 GDBServer handles the event and calls proceed_all_lwps
 This calls proceed_one_lwp and installs single-step breakpoints on all
 the threads that need one.

 Now since thread 1 needs to install a single-step breakpoint and is at pc B
 (different than thread 2), a step-over is not initiated and get_next_pc
 is called to figure out the next instruction from pc B.

 However it may just be that thread 3 as a single step breakpoint at pc
 B. And thus get_next_pc fails.

This situation is tested with non-stop-fair-events.exp.

In other words, single-step breakpoints are installed in proceed_one_lwp
for each thread.  GDBserver proceeds two threads for resume_step, as
requested by GDB, and the thread proceeded later may see the single-step
breakpoints installed for the thread proceeded just now.

Tested on gdbserver-native/-m{thumb,arm} no regressions.
