Rename common to gdbsupport
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.

remote: one struct remote_state per struct remote_target
'struct remote_state' today contains per-connection state, however
there's only a single global instance of that type. In order to
support multiple connections, we must have one such object per
connection.
Thus this patch eliminates the 'remote_state' global in favor of
having a remote_state instance per remote_target instance.
The get_remote_state free function is eliminated as well, by making it
a remote_target method instead.
The patch then fixes the fallout by making all free functions that
refer to get_remote_state() directly or indirectly be methods of
remote_target too.
Likewise, remote-fileio.c and remote-notif.c routines are
parameterized with a remote_target pointer too, so they can call into
the right remote_target instance.
References to the global 'get_remote_state ()->remote_desc' to tell
whether the remote target is open (!= nullptr) must be replaced with
something else:
- Command implementations use a new get_current_remote_target free
function.
- remote_target::open_1 checks the exception type instead.
Finally, remote_target and extended_remote_target are made
heap-allocated targets. As with the earlier core target patches, it
still won't be possible to have more than one remote_target instance
in practice, but this puts us closer.
