This is the patch to add new option '--skip-unavailable' to MI
commands '-stack-list-{locals, arguments, variables}'. This patch
extends list_args_or_locals to add a new parameter 'skip_unavailable',
and don't list locals or arguments if values are unavailable and
'skip_unavailable' is true.
This is inspecting a trace frame (tfind mode), where only a few
locals have been collected.
-stack-list-locals, no switch vs new switch:
-stack-list-locals --simple-values
^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
-stack-list-locals --skip-unavailable --simple-values
^done,locals=[{name="array",type="unsigned char [2]"}]
-stack-list-arguments, no switch vs new switch:
-stack-list-arguments --simple-values
^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}]
-stack-list-arguments --skip-unavailable --simple-values
^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}]
-stack-list-variables, no switch vs new switch:
-stack-list-variables --simple-values
^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
-stack-list-variables --skip-unavailable --simple-values
^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}]
tests are added to test these new options.

There's no need for deprecated_xfer_memory nowadays. Memory access
goes through target_xfer_partial/TARGET_OBJECT_MEMORY, etc. In fact,
the remote target already handles that, and is deferring to the same
helpers the deprecated_xfer_memory hook is. Basically, only a few
adjustments to make these helper routines's interfaces closer to
target_xfer_partial's were necessary.
Tested on x86_64 Fedora 17 w/ gdbserver.
