This patch series adds support for software single step and conditional
breakpoints on ARM in GDBServer.

Patches 1 and 2 fix general issues in the software single step control flow.

Patches 3 to 5 Removes the too simple implementations of software single
step that were in place and paves to way for full software single step to
be implemented.

Patches 6 and 7 Prepares the sharing of the software single step code for
ARM in GDB with GDBServer.

Patch 8 Implements the support for ARM software single step.

Patch 9 Adds support for while-stepping actions.

Patch 10 Adds supports for conditional breakpoints in GDBServer.

This patchset has no observed regressions, tested on ubuntu 14.04 ARMv7 and x86.
With gdbserver-{native,extended} / { -marm -mthumb }

Note also that while I could not test directly thumbv1 instructions with gcc
-marmv4t , manual testing of the software single step was done for thumv1
instructions.
