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.

79b40d1127 docs/machine*: Remove explicit targets and "machine." prefixes on classes.
With currentmodule:: set properly, none are needed. Extra "machine." prefix
produces wrong indexing data.

7d7243f44c docs/machine.*: Use proper class case in method headers.
Class designator will be used as is in indexes, so must match actual class
name.

c8b7628094 docs/machine.*: Add "currentmodule:: machine" directive.
Makes sure that classes described in these separate files are properly
designated as belonging to "machine" module in indexes.

c816b89353 docs/library/machine.I2C: Update to reflect ESP8266 implementation.
This machine.I2C documentation is now closer to a more port-neutral
description, although there are still differences between WiPy and
ESP8266.

70ff7350e7 stmhal, cc3200: Change i2c.scan() method to scan addresses 0x08-0x77.
A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx
are reserved.  The scan() method is changed to reflect this, along with
the docs.
