Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

We need at least one per IN/IRQ endpoint, as well as at least 3 for
every OUT endpoint. Plus some more depending on the application,
in case of cardem there could be one in uart_tx and one in uart_rx.
So for cardem, it should be 7 per slot, resulting 14 for dual-slot
devices like OWHW and QMOD.
Given that we have plenty of RAM available (utilization up from 49%
to 56% with this change), we can be on the comfortable size and
easily have 20 buffers for now.
Future MITM / triple-play applications likely need more.

This helps when debugging the firmware, as it shows the current
utliization of the 10-msgb-talloc pool.

There have been tons of format-string related bugs in our code which
we never discovered due to disabling -Wformat. Let's fix that.

the curent local copies of libosmocore headers + source is a temporary
hack anyway. We should instead rely on a system-wide install of
libosmocore cross-compiled for arm-none-eabi. But leave that as a
second (later) step beyond this patch.

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.
