This is a generally useful feature and because it's part of the object
model it cannot be added at runtime by some loadable Python code, so enable
it on the standard unix build.
The last argument of TUD_CDC_DESCRIPTOR() is the endpoint size (or
wMaxPacketSize), not the CDC RX buffer size (which can be larger than the
endpoint size).

When installing WS firmware, the very first GET_STATE can take several
seconds to respond (especially with the larger binaries like
BLE_stack_full).
Allows stm.rfcore_sys_hci to take an optional timeout, defaulting to
SYS_ACK_TIMEOUT_MS (which is 250ms).

The flash can sometimes be in an already-unlocked state, and attempting to
unlock it again will cause an immediate reset. So make _Flash.unlock()
check FLASH_CR_LOCK to get the current state.
Also fix some magic numbers for FLASH_CR_LOCK AND FLASH_CR_STRT.
The machine.reset() could be removed because it no longer crashes now that
the flash unlock is fixed.

This commit adds a script that can be run on-device to install FUS and WS
binaries from the filesystem. Instructions for use are provided in
the rfcore_firmware.py file.
The commit also removes unneeded functionality from the existing rfcore.py
debug script (and renames it rfcore_debug.py).
The new functions provide FUS/WS status, version and SYS HCI commands:
- stm.rfcore_status()
- stm.rfcore_fw_version(fw_id)
- stm.rfcore_sys_hci(ogf, ocf, cmd)
Changes are:
- Fix missing IRQ handler when SDMMC2 is used instead of SDMMC1 with H7
MCUs.
- Removed outdated H7 series compatibility macros.
- Defined common IRQ handler macro for F4 series.
It requires mp_hal_time_ns() to be provided by a port. This function
allows very accurate absolute timestamps.
Enabled on unix, windows, stm32, esp8266 and esp32.

With a warning that this way of constructing software I2C/SPI is
deprecated. The check and warning will be removed in a future release.
This should help existing code to migrate to the new SoftI2C/SoftSPI types.

Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances. Such
construction is now split to explicit soft and non-soft types.
This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.
This is a breaking change for use of software-based I2C and SPI. Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:
machine.I2C(-1, ...) -> machine.SoftI2C(...)
machine.I2C(scl=scl, sda=sda) -> machine.SoftI2C(scl=scl, sda=sda)
machine.SPI(-1, ...) -> machine.SoftSPI(...)
machine.SPI(sck=sck, mosi=mosi, miso=miso)
-> machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)
Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

Make the instructions more complete by documenting all needed steps for
starting from scratch. Also add a section for MSYS2 since the Travis build
uses it as well and it's a good alternative for Cygwin. Remove the mingw32
reference since it's not readily available anymore in most Linux distros
nor compiles successfully.
The device info table has a different layout when core 2 is in FUS mode.
In particular it's larger than the 32 bytes used when in WS mode and if the
correct amount of space is not allocated then the end of the table may be
overwritten with other data (eg with FUS version 0.5.3). So update the
structure to fix this.
Also update rfcore.py to disable IRQs (which are enabled by rfcore.c), to
not depend on uctypes, and to not require the asm_thumb emitter.

For time-based functions that work with absolute time there is the need for
an Epoch, to set the zero-point at which the absolute time starts counting.
Such functions include time.time() and filesystem stat return values. And
different ports may use a different Epoch.
To make it clearer what functions use the Epoch (whatever it may be), and
make the ports more consistent with their use of the Epoch, this commit
renames all Epoch related functions to include the word "epoch" in their
name (and remove references to "2000").
Along with this rename, the following things have changed:
- mp_hal_time_ns() is now specified to return the number of nanoseconds
since the Epoch, rather than since 1970 (but since this is an internal
function it doesn't change anything for the user).
- littlefs timestamps on the esp8266 have been fixed (they were previously
off by 30 years in nanoseconds).
Otherwise, there is no functional change made by this commit.

This commit removes release-specific builds for the esp8266 and makes the
normal build of the GENERIC board more like the release build. This makes
esp8266 like all the other ports, for which there is no difference between
a daily build and a release build, making things less confusing.
Release builds were previously defined by UART_OS=-1 (disable OS messages)
and using manifest_release.py to include more frozen modules.
The changes in this commit are:
- Remove manifest_release.py.
- Add existing modules from manifest_release.py (except example code)
to the GENERIC board's manifest.py file.
- Change UART_OS default to -1 to disable OS messages by default.

PPP support was disabled in 96008ff59a -
marked as "unsupported" due to an early IDF v4 release. With the currently
supported IDF v4.x version - 4c81978a - it appears to be working just fine.
This commit changes the default logging level on all esp32 boards to ERROR.
The esp32 port is now stable enough that it makes sense to remove the info
logs to make the output cleaner, and to match other ports. More verbose
logging can always be reenabled via esp.osdebug().
This also fixes issue #6354, error messages from NimBLE: the problem is
that ble.active(True) will cause the IDF's NimBLE port to reset the
"NimBLE" tag back to the default level (which was INFO prior to this
commit). Even if the user had previously called esp.osdebug(None), because
the IDF is setting the "NimBLE" tag back to the default (INFO), the
messages will continue to be shown.
The one quirk is that if the user does want to see the additional logging,
then they must call esp.osdebug(0, 3) after ble.active(True) to undo the
IDF setting the level back to the default (now ERROR). This means that
it's impossible (via Python/esp.osdebug) to see stack-startup logging,
you'd have to recompile with the default level changed back to INFO.
Support freezing modules via manifest.py for consistency with the other
ports. In essence this comes down to calling makemanifest.py and adding
the resulting .c file to the build. Note the file with preprocessed qstrs
has been renamed to match what makemanifest.py expects and which is also
the name all other ports use.
The mpconfigport.h file is an internal header and should only ever be
included once by mpconfig.h.

This allows prototyping rfcore.c improvements from Python.
This was mostly written by @dpgeorge with small modifications to work after
rfcore_init() by @jimmo.
Before this change there was up to a 128ms delay on incoming payloads from
CPU2 as it was polled by SysTick. Now the RX IRQ immediately schedules the
PendSV.
This is required to allow using WS firmware newer than 1.1.1 concurrently
with USB (e.g. USB VCP). It prevents CPU2 from modifying the CLK48 config
on boot.
Tested on WS=1.8 FUS=1.1.
