ed14435a8e extmod/modbluetooth: Refactor stack/hci/driver/port bindings.
Previously the interaction between the different layers of the Bluetooth
stack was different on each port and each stack.  This commit defines
common interfaces between them and implements them for cyw43, btstack,
nimble, stm32, unix.

27767aafa2 lib/libm_dbl: Add round.c source code.
This code is imported from musl, to match existing code in libm_dbl.

The file is also added to the build in stm32/Makefile.  It's not needed by
the core code but, similar to c5cc64175b,
allows round() to be used by user C modules or board extensions.

5264478007 extmod/modussl_mbedtls: Integrate shorter error strings.
The stm32 and esp32 ports now use shorter error strings for mbedtls errors.
Also, MBEDTLS_ERROR_C is enabled on stm32 by default to get these strings.

710426024a all: Factor gchelper code to one place and use it for unix & ARM ports.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port.  This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.

Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.

The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

8ee2e1fdbc stm32/mboot: Expose custom DFU USB VID/PID values at makefile level.
In mboot, the ability to override the USB vendor/product id's was added
back in 5688c9ba09.  However, when the main
firmware is turned into a DFU file the default VID/PID are used there.
pydfu.py doesn't care about this but dfu-util does and prevents its use
when the VID/PID don't match.

This commit exposes BOOTLOADER_DFU_USB_VID/PID as make variables, for use
on either command line or mpconfigboard.mk, to set VID/PID in both mboot
and DFU files.

30840ebc99 all: Enable extra conversion warnings where applicable.
Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out
implicit floating point conversions, and add extra Travis builds using
MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found
previously.  For the unix port -Wsign-comparison is added as well but only
there since only clang supports this but gcc doesn't.

c5cc64175b ports: Add lib/libm/roundf.c to bare-metal Makefile's.
This function is not used by the core but having it as part of the build
allows it to be used by user C modules, or board extensions.  The linker
won't include it in the final firmware if it remains unused.

Move extmod/modbluetooth_nimble.* to extmod/nimble.  And move common
Makefile lines to extmod/nimble/nimble.mk (which was previously only used
by stm32).  This allows (upcoming) btstack to follow a similar structure.

799b6d1e0c extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it.  It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.

For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile.  This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.

48b25a841b stm32: Add machine.Timer with soft timer implementation.
This commit adds an implementation of machine.Timer backed by the soft
timer mechanism.  It allows an arbitrary number of timers with 1ms
resolution, with an associated Python callback.  The Python-level API
matches existing ports that have a soft timer, and is used as:

    from machine import Timer
    t = Timer(freq=10, callback=lambda t:print(t))
    ...
    t = Timer(mode=Timer.ONE_SHOT, period=2000, callback=lambda t:print(t))
    ...
    t.deinit()

a5d97f1db9 stm32: Add soft timer implementation, using SysTick at 1ms resolution.
This commit adds an implementation of a "software timer" with a 1ms
resolution, using SysTick.  It allows unlimited number of concurrent
timers (limited only by memory needed for each timer entry).  They can be
one-shot or periodic, and associated with a Python callback.

There is a very small overhead added to the SysTick IRQ, which could be
further optimised in the future, eg by patching SysTick_Handler code
dynamically.

902bb4ceae stm32: Extract port-specific Nimble implementation.
On other ports (e.g. ESP32) they provide a complete Nimble implementation
(i.e. we don't need to use the code in extmod/nimble). This change
extracts out the bits that we don't need to use in other ports:
 - malloc/free/realloc for Nimble memory.
 - pendsv poll handler
 - depowering the cywbt

Also cleans up the root pointer management.

5fd62c8992 stm32: Remove SystemInit funcs, use stm32lib versions instead.
stm32lib now provides system_stm32XXxx.c source files for all MCU variants,
which includes SystemInit and prescaler tables.  Since these are quite
standard and don't need to be changed, switch to use them instead of custom
variants, making the start-up code cleaner.

The SystemInit code in stm32lib was checked and is equivalent to what is
removed from the stm32 port in this commit.

04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

SCSI can support multiple logical units over the one interface (in this
case over USBD MSC) and here the MSC code is reworked to support this
feature.  At this point only one LU is used and the behaviour is mostly
unchanged from before, except the INQUIRY result is different (it will
report "Flash" for both flash and SD card).

97753a1bbc stm32: Move factory reset files and code to separate source file.
The new function factory_reset_make_files() populates the given filesystem
with the default factory files.  It is defined with weak linkage so it can
be overridden by a board.

This commit also brings some minor user-facing changes:

- boot.py is now no longer created unconditionally if it doesn't exist, it
  is now only created when the filesystem is formatted and the other files
  are populated (so, before, if the user deleted boot.py it would be
  recreated at next boot; now it won't be).

- pybcdc.inf and README.txt are only created if the board has USB, because
  they only really make sense if the filesystem is exposed via USB.

aa7b32c811 stm32/dac: Rework DAC driver to use direct register access.
This patch makes the DAC driver simpler and removes the need for the ST
HAL.  As part of it, new helper functions are added to the DMA driver,
which also use direct register access instead of the ST HAL.

Main changes to the DAC interface are:

- The DAC uPy object is no longer allocated dynamically on the heap,
  rather it's statically allocated and the same object is retrieved for
  subsequent uses of pyb.DAC(<id>).  This allows to access the DAC objects
  without resetting the DAC peripheral.  It also means that the DAC is only
  reset if explicitly passed initialisation parameters, like "bits" or
  "buffering".

- The DAC.noise() and DAC.triangle() methods now output a signal which is
  full scale (previously it was a fraction of the full output voltage).

- The DAC.write_timed() method is fixed so that it continues in the
  background when another peripheral (eg SPI) uses the DMA (previously the
  DAC would stop if another peripheral finished with the DMA and shut the
  DMA peripheral off completely).

Based on the above, the following backwards incompatibilities are
introduced:

- pyb.DAC(id) will now only reset the DAC the first time it is called,
  whereas previously each call to create a DAC object would reset the DAC.
  To get the old behaviour pass the bits parameter like: pyb.DAC(id, bits).

- DAC.noise() and DAC.triangle() are now full scale.  To get previous
  behaviour (to change the amplitude and offset) write to the DAC_CR (MAMP
  bits) and DAC_DHR12Rx registers manually.
