Re: add file I/O support when debugging an embedded target via jtag

Thank you for your comments on Bart Veer's original proposal and
subsequent patch for file I/O support when debugging via JTAG.

Proposal: http://sourceware.org/ml/gdb/2008-07/msg00045.html
Patch: http://sourceware.org/ml/gdb-patches/2008-08/msg00315.html

We now need to draw this to a conclusion and move on.

The principle objection to the patch is that it introduces a new target
ops stratum which might break other configurations or impede future
developments. During our initial investigation we came to the conclusion
that introducing a new stratum was the most elegant way to implement
this functionality in a generic manner. In his response to the original
proposal, Daniel wrote:

Is there anything we can now do to make the patch acceptable short of a
re-implemention to avoid introducing a new stratum?
