    Support for HWbreak/watchpoint across fork/vfork on arm-native
    
    This patch updates arm native support for hwbreak-/watchpoints to enable
    support for hwbreak-/watchpoints across fork/vfork. This involves changes to
    hwbreak-/watchpoint insertion mechanism to the modern way, by marking debug
    registers as needing update, but only really updating them on resume, which is
    necessary for supporting watchpoints in non-stop mode. This also updates a
    previously maintained per thread hwbreak-/watchpoint cache to a per process
    cache which allows target specific code to come in sync with gdb-linux calls to
    threads create/destroy and process fork/exit hooks.
