This error of building any EF targets was found on Windows if used with
make V=1 verbose output option. The '--verbose' python script option was
used by the Windows make as a part of python script file name with
'file not found' error. Now it works. Still can't get the cause of that
error, though...
Moves the CMSIS system_stm3210x.c from library.mk to the individual Makefiles for the F1 targets. This allows for custom SystemInit functions where necessary.
The ST USB code will automatically receive on any
endpoint that is opened but not in the NAK state.
Make sure we set OUT endpoints to NAK initially.
It also happily writes via a NULL pointer in ep->xfer_buff
which writes to address 0x0000_0000. Since address
0x0 is aliased onto the internal flash by the BOOT0/1 pins
and the internal flash is (normally) in the LOCKED state,
this write puts the internal flash into an errored state.
This errored state means that writes to internal flash
are no longer allowed and all further writes fail.
This is required so that we can always respond to HID and
CDC requests via the control endpoint (ep0). The F1/F3
implementation gets away with disabling these interfaces
because all of the ep0 handling is in the usbhook code
rather than (properly) split out into class-specific
drivers like it is done on the F4 implementation.

The CDC descriptor was not advertising support the the line
coding and serial state messages. This was preventing Mac
from sending the SetControlLineState message to indicate
that a DTE (ie terminal program) was present and reading
from the serial port.
We support (and depend on) the DTE indication now so this
was making CDC not work on Mac.
Linux seems to provide the indication regardless of whether
it is advertised in the descriptor or not.

The interface numbers differ for the HID interface between
the BL and FW. This is required to keep windows happy.
In HID+CDC, the CDC interfaces must come first with HID last
which makes it #2. In HID only mode, we can't use #2 for HID
since windows doesn't like the first/only interface to be
anything other than #0.
