b697c89009 extmod: Merge old fsusermount.h header into vfs.h and vfs_fat.h.

7a7516d40d extmod/machine_signal: Implement "signal" abstraction for machine module.
A signal is like a pin, but ca also be inverted (active low). As such, it
abstracts properties of various physical devices, like LEDs, buttons,
relays, buzzers, etc. To instantiate a Signal:

pin = machine.Pin(...)
signal = machine.Signal(pin, inverted=True)

signal has the same .value() and __call__() methods as a pin.

dcb9ea7215 extmod: Add generic VFS sub-system.
This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
agnostic to the underlying filesystem type, and just require an object with
the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
then be mounted.

These mp_vfs_XXX functions would typically be used by a port to implement
the "uos" module, and mp_vfs_open would be the builtin open function.

This feature is controlled by MICROPY_VFS, disabled by default.

f5f4cdae89 extmod/vfs_fat: Rework so it can optionally use OO version of FatFS.

MICROPY_FATFS_OO.  Otherwise a port can continue to use the FatFs code
without any changes.

304cfda8c4 py/stream: Move ad-hoc ioctl constants to stream.h and rename them.
The constants MP_IOCTL_POLL_xxx, which were stmhal-specific, are moved
from stmhal/pybioctl.h (now deleted) to py/stream.h.  And they are renamed
to MP_STREAM_POLL_xxx to be consistent with other such constants.

All uses of these constants have been updated.

b7df3e541a extmod/vfs_fat: Implement POSIX behaviour of rename, allow to overwrite.
If the destination of os.rename() exists then it will be overwritten if it
is a file.  This is the POSIX behaviour, which is also the CPython
behaviour, and so we follow suit.

See issue #2598 for discussion.

a081b49d55 extmod/modframebuf: Optimise fill and fill_rect methods.
Fill is a very common operation (eg to clear the screen) and it is worth
optimising it, by providing a specialised fill_rect function for each
framebuffer format.

This patch improved the speed of fill by 10 times for a 16-bit display
with 160*128 pixels.

Also add blit() and fill_rect() methods.

e429daa572 extmod/utime_mphal: Fix implementation of new semantics of ticks_diff().
Now the function properly uses ring arithmetic to return signed value
in range (inclusive):
[-MICROPY_PY_UTIME_TICKS_PERIOD/2, MICROPY_PY_UTIME_TICKS_PERIOD/2-1].

That means that function can properly process 2 time values away from
each other within MICROPY_PY_UTIME_TICKS_PERIOD/2 ticks, but away in
both directions. For example, if tick value 'a' predates tick value 'b',
ticks_diff(a, b) will return negative value, and positive value otherwise.
But at positive value of MICROPY_PY_UTIME_TICKS_PERIOD/2-1, the result
of the function will wrap around to negative -MICROPY_PY_UTIME_TICKS_PERIOD/2,
in other words, if a follows b in more than MICROPY_PY_UTIME_TICKS_PERIOD/2 - 1
ticks, the function will "consider" a to actually predate b.

6ed5583f8c extmod/utime_mphal: ticks_diff(): switch arg order, return signed value.
Based on the earlier discussed RFC. Practice showed that the most natural
order for arguments corresponds to mathematical subtraction:

ticks_diff(x, y) <=> x - y

Also, practice showed that in real life, it's hard to order events by time
of occurance a priori, events tend to miss deadlines, etc. and the expected
order breaks. And then there's a need to detect such cases. And ticks_diff
can be used exactly for this purpose, if it returns a signed, instead of
unsigned, value. E.g. if x is scheduled time for event, and y is the current
time, then if ticks_diff(x, y) < 0 then event has missed a deadline (and e.g.
needs to executed ASAP or skipped). Returning in this case a large unsigned
number (like ticks_diff behaved previously) doesn't make sense, and such
"large unsigned number" can't be reliably detected per our definition of
ticks_* function (we don't expose to user level maximum value, it can be
anything, relatively small or relatively large).

eaef6b5324 extmod/machine_i2c: Use writes not reads in i2c.scan().
As per discussion in #2449, using write requests instead of read requests

ones that are write-only.  Even a read-only I2C device has to implement
writes in order to be able to receive the address of the register to read.

b932b2dd1f extmod/machine_spi: Use delay_half, not baudrate, for internal timing.
The delay_half parameter must be specified by the port to set up the
timing of the software SPI.  This allows the port to adjust the timing
value to better suit its timing characteristics, as well as provide a
more accurate printing of the baudrate.

5bb28c7f10 extmod/machine_spi: Simplify SPI xfer function to only take one buf len.
There is no need to take src_len and dest_len arguments.  The case of
reading-only with a single output byte (originally src_len=1, dest_len>1)
is now handled by using the output buffer as the input buffer, and using
memset to fill the output byte into this buffer.  This simplifies the
implementations of the spi_transfer protocol function.

219245e10f extmod/machine_i2c: Add support for the addrsize parameter in mem xfers.
The memory read/write I2C functions now take an optional keyword-only
parameter that specifies the number of bits in the memory address.
Only mem-addrs that are a multiple of 8-bits are supported (otherwise
the behaviour is undefined).

Due to the integer type used for the address, for values larger than 32
bits, only 32 bits of address will be sent, and the rest will be padded
with 0s. Right now no exception is raised when that happens. For values
smaller than 8, no address is sent. Also no exception then.

Tested with a VL6180 sensor, which has 16-bit register addresses.

Due to code refactoring, this patch reduces stmhal and esp8266 builds
by about 50 bytes.

7b901d6fb7 extmod/moduzlib: DecompIO: Add support for gzip-formatted streams.
This uses extension introduced in CPython 3.5: if wbits (dictionary size
code) has value 16 + 8..15, it means that gzip-formatted stream expected.
