This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

This is more preparation bits for multi-target support.
In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID. E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines. Or maybe we've loaded multiple
instances of the same core file. Etc.
To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively. I.e.,
each process_stratum instance has its own thread/process number space.
As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int. E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.
In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid. Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.
So that's what this patch does. In a bit more detail:
- Changes a number of functions and methods to take a thread_info or
inferior pointer instead of a ptid_t or int parameter.
- Changes a number of structure fields from ptid_t/int to inferior or
thread_info pointers.
- Uses the inferior_thread() function whenever possible instead of
inferior_ptid.
- Uses thread_info pointers directly when possible instead of the
is_running/is_stopped etc. routines that require a lookup.
- A number of functions are eliminated along the way, such as:
int valid_gdb_inferior_id (int num);
int pid_to_gdb_inferior_id (int pid);
int gdb_inferior_id_to_pid (int num);
int in_inferior_list (int pid);
- A few structures and places hold a thread_info pointer across
inferior execution, so now they take a strong reference to the
(refcounted) thread_info object to avoid the thread_info pointer
getting stale. This is done in enable_thread_stack_temporaries and
in the infcall.c code.
- Related, there's a spot in infcall.c where using a RAII object to
handle the refcount would be handy, so a gdb::ref_ptr specialization
for thread_info is added (thread_info_ref, in gdbthread.h), along
with a gdb_ref_ptr policy that works for all refcounted_object types
(in common/refcounted-object.h).
