[PATCH 0/3] Apply fixme notes for multi-target support

[Christina Schimpe <christina.schimpe@intel.com>]

Hi all, 

this is a set of patches that apply the fixme notes described in commit 5b6d1e4
"Multi-target support".

"You'll notice that remote.c includes some FIXME notes.  These refer to
the fact that the global arrays that hold data for the remote packets
supported are still globals.  For example, if we connect to two
different servers/stubs, then each might support different remote
protocol features.  They might even be different architectures, like
e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a
host/controller scenario as a single program.  That isn't going to
work correctly today, because of said globals.  I'm leaving fixing
that for another pass, since it does not appear to be trivial, and I'd
rather land the base work first.  It's already useful to be able to
debug multiple instances of the same server (e.g., a distributed
cluster, where you have full control over the servers installed), so I
think as is it's already reasonable incremental progress."

Due to the global array and variables used by all remote targets, the command
line configuration for remote targets' features before this set of patches
affected existing remote targets and future remote targets.  It was not
possible to individually configure a remote target's feature.
This behavior is now different.  With this patch series, the currently selected
remote target's as well as a future remote target's feature set can be
configured, without affecting the feature sets of the existing remote targets.

Any feedback about this series of patches is appreciated.

Regards,
Christina
