The SoftI2C constructor is now used soley to create SoftI2C instances, it
can no longer delegate to create a hardware-based I2C instance.

Also rename machine_i2c_type to mp_machine_soft_i2c_type. These changes
make it clear that it's a soft-I2C implementation, and match SoftSPI.

Some downstream projects may use tags in their repositories for more than
just designating MicroPython releases. In those cases, the
makeversionhdr.py script would end up using a different tag than intended.
So tell `git describe` to only match tags that look like a MicroPython
version tag, such as `v1.12` or `v2.0`.
Zephyr v2.4.0 added a const qualifier to usages of struct device to
allow storing device driver instances exclusively in flash and thereby
reduce ram footprint.

The use of -S ensures that only the CPython standard library is accessible,
which makes tests run the same regardless of any site-packages that are
installed. It also improves start-up time of CPython, reducing the overall
time spent running the test suite.
tests/basics/containment.py is updated to work around issue with old Python
versions not being able to str-format a dict-keys object, which becomes
apparent when -S is used.

A read-only memoryview object is a better representation of the data, which
is owned by the ubluetooth module and may change between calls to the
user's irq callback function.

Calling the bytes constructor on a bytes object returns the original bytes
object. This saves allocating a new instance, and matches CPython.

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.
Prior to this commit, uos.chdir('/') followed by uos.stat('noexist') would
succeed that stat even though the entry did not exist (some other functions
like listdir would have similar issues). This is because, if the current
directory was the root and the path was relative, mp_vfs_lookup_path would
return success for bad paths.

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.

is needed so the test can run on CPython versions prior to "@=" operator
support.

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.

To portably get the Epoch. This is simply aliased to localtime() on ports
that are not timezone aware.

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.
