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
NOTE: it has only be tested for the SIMtrace board

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.

The current protocol was card-emulation specific. The new protocol is
generic/flexible enough to accommodate both tracing and card emulation,
as well as modem control and other future extensions.
