make V=1 can be used to echo all compilation commands, which is useful
because it allows IDEs to parse the gcc output in oder to properly index
the source files using the actual defines passed to the compiler.

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.

this change is mainly relevant for the SIMtrace board, but also
affects the others.
First we ensure VCC_PHONE is not forwarded to VCC_SIM because the
card could affect the signal (card could draw too much current or
feed back current in).
next we disable VCC_SIM. the card slot does not need to be
powered, and the FPF2019 leaks current back to VCC_PHONE, even
with forwarding disabled (the reverse current protection only
kicks in when VCC_PHONE is briefly shorted to ground, but still
leaks 0.6V).
enable the ADC channels normally used to measure VCC, even if
not used. the dedicated ADC pins leak current when left
unconfigured. enabling them puts them in high impedance.

the reset/ATR handling has been heavily updated/fixed.
instead of using the timer counter peripheral to handle
the waiting time and corresponding timeout, the USART peripheral
internal timeout mechanism is used.
this is particularly important for the SIMtrace board since the
clock signal is not connected to the timer counter.
thus this change adds card emulation support for SIMtrace boards.
Fi and Di have been properly rename to F and D since the "i"
stands only for an "indicated" value, not the actual value.
this does not change the USB protocol (the variable have just been
renamed).
additional variables store more information about the card
capabilities

The original code assumes that calls to PIO_ConfigureIt() are only
made once e.g. during board start-up. Hoewever, we call those
at USB SetConfiguration time, when we know which particular hardware
function we are supposed to perform. This means that after the host
has issued SetConfiguration more than a given number of times, the
code will assert() due to overflow of the static array.
Let's check if we already have allocated an array slot for a given pin
and reuse that allocated array bucket rather than allocating new ones
for the same pin.

Reading the Unique ID from flash is a rather tricky procedure: After the
STUI command has been issued, we cannot read normal flash anymore.
Rather, the unique ID is mapped at 0x00000000. This is unfortuantely
also where the exception vector table is stored.
EEFC_ReadUniqueID() is already linked to RAM, which is good. Hoewver,
if an Interrupt happens between STUI and SPUI, then we try to access
the vector table and code from flash, which is illegal. We run into
a hardfault and stay there until the watchdog resets the processor.

As reported in https://osmocom.org/issues/4335, there appear to

it needs to be *that* large.

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.

The new SIMTRACE_MSGT_BD_CEMU_CONFIG command can be used to set/change
a bitmask of optional features that can be enabled in the simtrace
by the host software. This is useful for enabling features in the
firmware which are not supported by older host utilities.
The firmware will return the actually set/configured features in
response.
The feature bitmask is not yet used anywhere; it will be by subequent
patches.

A function that is called to set the state should not in itself
contain logic to issue further state changes.
Let's shift the related block out to the end of card_emu_io_statechg(),
which is the only source of card_set_state() calls for the
WAIT_{POWER,CLK,RST} states anyway.
As an added benefit, the block of statements is now also executed if
there's no state change - something that was prevented by the
"if old == new" state guard at the top of card_set_state(). I believe
this may help us to cover more (non-standard) card activation sequences.

So far, we called card_emu_io_statechg() from interrupt context, which
was safe with the current code. However, as we want to trigger a more
comprehensive reset of data structures, including the flushing of
message queues, it is best to shift this processing from interrupt
context to main loop context.

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.
