4fd40ca0d2 gcs uploader: add support for "Safe Boot" to the GCS uploader
When halted in the bootloader or while rescuing a board, the
user can press the "Safe Boot" button in the uploader gadget
to force the FW to boot with a default hwsettings configuration.

The default conditions of the hwsettings uavo will disable all
optional modules, disable all serial port config, and ensure that
the board can communicate via the USB HID telemetry interface.

Once booted in this mode, a user can easily reconfigure the
hwsettings uavo through the config GUI and save the fixed
settings to the board to be used on the next reboot.  No need
to wipe all settings just to recover from a non-functional
HW config.

NOTE: The GCS needs to grow some very clear visual clues to
      indicate when the board has booted in safe mode.  The
      firmware helpfully raises a (new) critical alarm called
      BootFault whenever it boots in safe mode.

4d2760f11d cc bl: allow bootloader to force safe-boot into firmware
This can be used by the GCS firmware uploader widget to boot
the firmware with a (temporarily) defaulted hwsettings uavo
so that a user can easily recover from a bad/incompatible
hwsettings configuration without wiping all settings.

This uses the same mechanism that the BootFault auto-recovery
code already uses in the CC firmware.  The auto-recovery is
triggered by setting the failed-boot counter to a maximum
value forcing recovery on the next FW init.

b94f4b49a4 usb: major refactoring of USB descriptors, CDC and HID
Summary of changes:
 * USB CDC and HID drivers are completely split apart.
   * This will allow different max buffer sizes for HID and CDC.
 * USB descriptors have been overhauled:
   * Proper structs/macros/enums declared for USB (see pios_usb_defs.h)
   * Two common descriptor definitions.  One for HID+CDC another for HID only.
     See pios_usb_desc_{hid_cdc,hid_only}.c for details.
   * Long standing bugs in OP USB descriptors became much more obvious with the
     new struct definitions.
   * Board specific USB initialization is now in pios_usb_board_data.h in each build target.
   * Definition of USB descriptors is now entirely indpendent of STM32 libs.
     Glue into STM32 libs is provided by pios_usbhook.c.
 * Removed a lot of stale/irrelevant USB #defines throughout the tree.
 * Improved naming consistency throughout USB code:
   * PIOS_USB_HID_* now refers to the HID endpoint code.
   * PIOS_USB_CDC_* now refers to the CDC endpoint code.
   * PIOS_USB_* now refers to the low-level USB code.
   * PIOS_USB_BOARD_* now refers to board-specific USB data
   * PIOS_USBHOOK_* is glue between PIOS and STM32 USB libs.
   * struct usb_* and enum usb_* and USB_* and HID_* are all types from the USB spec.
 * Shrunk the buffer size on the CDC call mgmt endpoint to save some RAM.
 * Made a few more USB related variables static to save some RAM.

075eb65603 bootfault: fail initialization if no telemetry link is configured
This detects a locked out state and fails the init.  The new
bootfault detection code will automatically drop to default
hwsettings after 3 consecutive boot failures.  That will put
the board back into an unlocked state where the user can now
enable a telemetry link using the GCS and everything will be
OK.

NOTE: Any configured telemetry link will be considered enough
      to boot up.  If you only configure a serial telemetry
      link but don't know how to hook anything up to it, this
      will not save you.

As the ultimate recovery, you can always load firmware on the
board that wipes the settings entirely and start over.

5c0921e92c fault: add optional fault insertion module
This module and its associated settings uavo can be used
to test various fault conditions during initialization.

To enable the module, add the TEST_FAULTS=YES to your make
command line:
  make fw_coptercontrol TEST_FAULTS=YES

Once this module is part of your firmware load, you can
enable it in the hwsettings uavo and then select the
type of fault to insert by editing the faultsettings uavo.
On the next reset, the configured fault will be inserted
into the init sequence to allow you to test the boot fault
recovery code.

With a fault inserted, you should see 3 failed boot attempts
followed by a successful (recovery) boot.  You will see the
BootFault alarm set to Critical, and the RAM version of your
hwsettings will be reset to defaults.  Since the defaults have
all optional modules disabled, the fault module will be out of
the way during the recovery boot.

You can then "Load" the flash version of the hwsettings uavo
in the object browser, disable the Fault module and then "Save"
the hwsettings module back to the board.  The next reset will
boot normally without the fault inserted.

f886af186d bootfault: add support for recovery from init failures
After 3 failed warm start attempts, the init sequence
will force the RAM version of the HWSettings object
to its defaults.  This should allow a user to regain
connectivity to a board that is continually faulting
during init.

This is accomplished by:
 - Incrementing a boot counter that is stored in the
   STM32 BKP registers.  These registers survive a
   warm start but are cleared on a cold start (ie. powerup).
 - On multiple failures, force hwsettings to defaults
   and raise the (new) BootFault alarm to prevent arming.
 - Resetting the boot counter whenever the system manages
   to successfully run the System Module task.

NOTE: This does not actually change the hwsettings object in
      flash.  That's up to the user.

This is intended to catch ONLY faults during early initialization.
It should not be used to recover from faults after the application
is up and running.

1543a6dbd3 hwsettings: allow disabling of USB telemetry entirely
The GCS hwsettings config widget now disallows any
configuration that disables both HID and VCP telemetry
over the USB port.

The firmware will allow it if the UAVObj is set manually.

This allows a mechanism to reduce RAM usage by another
500 more bytes if USB telemetry can be sacrificed in
certain configurations.

fa9702db97 gcs serial: fix broken baud rate selection
The difference between 56000 and 57600 baud is very
important.

When using a USB to serial adapter that is capable
of synthesizing arbitrary baud rates, these errors
resulted in a completely mismatched/unusable serial
link.

2cf1fe93c6 com: don't block forever waiting for a transmitter
Not all transmitters will continue to run when disconnected.
USB is one example of this.  When the USB cable was disconnected,
any transmitter blocked here would wait forever.

This was particularly noticeable when the telemetry Tx task
blocked forever on USB disconnect.  This also resulted in
the telemetry Rx task blocking forever waiting on the UAVTalk
connection lock.

We now block for a max of 5s waiting for space in the transmit
buffer.

60969b57d8 usb-hid: split apart hwsettings for HID and VCP ports
This allows the HID and VCP functions to be configured
separately so that additional functions can be more easily
bound to the VCP port.

This change also provides a safety net that forces either
the HID or VCP to be configured for USB Telemetry.  This
safety net may vanish in the future once the GCS can check
it.  Disabling USB Telemetry entirely would save more than
400 bytes of RAM.

785a7ccd88 uavtalk: convert tx to use blocking send routines
The uavtalk layer was previously implementing a poor
version of packet fragmentation based on a hard-coded
max packet size.  Since this was hard-coded, there was
no guarantee that it would match the underlying devices.

Now that the COM layer sending routines support fragmentation,
remove fragmentation and use the COM layer directly.

This will support future buffer size reductions in the COM
layer.

80e0be3cec com: fragment transmitted buffers to match underlying device
PIOS_COM_SendBufferNonBlocking() will now fragment its buffer
to match the max size of the underlying device.

This allows the buffer size of the underlying device to shrink
below the maximum message size, thus allowing us to use smaller
buffers on memory-constrained platforms.
