Set CFLAGS on top of the Makefile, to avoid using the distribution's
default CFLAGS. In debian testing and unstable, -fcf-protection was
recently added to the default CFLAGS, but it cannot be used with the
cross compiler:

DFU flashing of apps sometimes aborts, and although rare this leads to
broken devices if no boot button or serial/jtag access exists, because
the bootloader will keep trying to start a half-flashed app that then
crashes at some point.
The easiest fix that works with existing bootloaders is to prepend a
small 512 byte stub that calculcates the crc and compares it with the
crc calculated at build time, and then either starts the actual app, or
sets the dfu flag and resets. This ensures we either have a working,
running app, or end up in the bootloader, ready to flash again.
For obvious reasons this only applies to dfu apps, and not to flash
targets like the actual bootloader itself.

This bl updater can be flashed as app and will update the bootloader and
then
delete itself before resetting the sam3, so the device will end up in
the newly
updated dfu bootloader afterwards, without having to press the
bootloader button
or requring any other manual interaction, ready to receive a new
application image.
Building the blupdater requires a previously built dfu-flash bootloader
bin file that
will then be embedded into the app during building.

Single threaded evaluation is (assumed to be!) left to right, depth
first - but with concurrent make using -j this breaks, because the
actual usb string header is generated after the attempt to concurrently
compile the code that needs it, since there is no explicit order among
the all: dependencies.
This is fixed by properly adding a dependency on that header.

Disable stack protector for all boards/apps by default, not only
qmod-dfu. Use 'make STACK_PROTECTOR=1' to enable.
This was recommened by Eric:
"I'd argue that we do not want this in general, since it adds canaries
to all functions that deal with buffers, and therefore impacts the
overall timing in a non determinstic way depending on inlining and
optimizations, while contributing nothing in non debug builds."

For some reason undefined symbols were downgraded to warnings, which
means building a firmware that calls missing functions (= address zero)
was perfectly fine, which of course made development more exciting....
This applies to builtins, too, printf of one char gets downgraded to
putchar, which we don't have, so disable builtins.

Fix having the version set to UNKNOWN in all packages built by OBS. The

generate a ".tarball-version" file with a version string like
"0.7.0.70-657c", but it did not get used because the path was wrong.

this adds the DFU as application, allowing to flash the bootloader.
a USB DFU alternative is added to flash the bootloader partition.
when the DFU is started as bootloader, the partition/alternative
to flash the bootloader is marked as "not available", and
ineffective.
the same happens for the application partition when DFU is started
as application.
this distinction is make at compile time, not at runtime, because
of size restrictions (the bootloader was already close to the
16 kB limit).
*_dfu_flash.bin should not be mixed with *_dfu_dfu.bin.
*_dfu_dfu.bin should be flashed as application using the already
existing DFU bootloader.
once this images is started (as application), the *_dfu_flash.bin
should be flashed as bootloader using the DFU application.
once the DFU bootloader has been flashed, soft resetting
(not re-powering) will cause the bootloader to start, allowing to
flash the application with a normal image (e.g. not DFU),
replacing the DFU application.
this switch to DFU only happens after downloading (e.g. flashing).
it is planned to have the DFU application erase itself after
flashing, but this is currently not implemented.

There's no point in building a DFU loeader that is to be flashed
via DFU - nor is there really any need for regular cardem/trace
that can be flahsed directly without DFU. If anyone needs those,
they can still build them - but let's not confuse the average other
user.

We now generalize the USB communiction and abandon the 'req_ctx'
structure inherited from openpcd. Instead we use the libosmocore 'msgb'
structure to handle incoming and outgoing USB tranfers. We also use
linuxlist-based msgb-queues for each endpoint.
This way we can easily check with 'diff' for differences in our code and
Atmel softpack. Also, this layout is more suitable for building various
different firmware images (e.g. factory-test, dfu-loader, main
application) for a variety of different boards (simtrace, owhw, qmod).
