And fix minor typo in docs when referring to SDCard class.

Damien George 8bec0e869d docs/machine.I2C: Add writevto method to write a vector of byte bufs.
This allows to efficiently send to an I2C slave data that is made up of
more than one buffer.  Instead of needing to allocate temporary memory to
combine buffers together this new method allows to pass in a tuple or list
of buffers.  The name is based on the POSIX function writev() which has
similar intentions and signature.

The reasons for taking this approach (compared to having an interface with
separate start/write/stop methods) are:
- It's a backwards compatible extension.
- It's convenient for the user.
- It's efficient because there is only one Python call, then the C code can
  do everything in one go.
- It's efficient on the I2C bus because the implementation can do
  everything in one go without pauses between blocks of bytes.
- It should be possible to implement this extension in all ports, for
  hardware and software I2C.

Further discussion is found in issue #3482, PR #4020 and PR #4763.

Damien George 34942d0a72 stm32/machine_uart: Change default UART timeout to 0, for non blocking.
It's more common to need non-blocking behaviour when reading from a UART,
rather than having a large timeout like 1000ms (the original behaviour).
With a large timeout it's 1) likely that the function will read forever if
characters keep trickling it; or 2) the function will unnecessarily wait
when characters come sporadically, eg at a REPL prompt.

Damien George 6fa830bfd8 docs/library/machine.Pin: Add PULL_HOLD constant to possible pin pulls.
As already mentioned in the docs, not all constants may be available on all
ports, so this is optional to implement.

Yonatan Goldschmidt 9521399044 docs/uos: Document extra requirements on stream objs passed to dupterm.
This is only correct for the extmod/uos_dupterm.c implementation however,
as e.g cc3200 implementation does the mp_load_method() itself, and anyway
requires `read` instead of `readinto`.

Damien George b16146d189 docs/machine: Change sleep to lightsleep and add timeout arguments.
The machine.sleep() function can be misleading because it clashes with
time.sleep() which has quite different semantics.  So change it to
machine.lightsleep() which shows that it is closer in behaviour to
machine.deepsleep().

Also, add an optional argument to these two sleep functions to specify a
maximum time to sleep for.  This is a common operation and underlying
hardware usually has a special way of performing this operation.

The existing machine.sleep() function will remain for backwards
compatibility purposes, and it can simply be an alias for
machine.lightsleep() without arguments.  The behaviour will be the same.

Paul Sokolovsky dd76c8dc0f docs/library/uctypes: Add examples and make general updates.
Examples are added to the beginning of the module docs, similarly to docs
for many other modules.

Improvements to grammar, style, and clarity. Some paragraphs are updated
with better suggestions. A warning added of the effect incorrect usage of
the module may have. Describe the fact that offset range used in one
defined structure is limited.

Damien George f5d46a88aa lib/utils/pyexec: Forcefully unlock the heap if locked and REPL active.
Otherwise there is really nothing that can be done, it can't be unlocked by

Damien George 217566b764 docs/library/network: Move specific network classes to their own file.
All concrete network classes are now moved to their own file (eg
network.WLAN.rst) and deconditionalised (remove ..only:: directives).  This
makes the network documentation the same for all ports.  After this change
there are no more "..only::" directives for different ports, and the only
difference among ports is the very front page of the docs.

Damien George d8e0320485 docs: Move WiPy specific Timer class to separate doc file.
The WiPy machine.Timer class is very different to the esp8266 and esp32
implementations which are better candidates for a general Timer class.  By
moving the WiPy Timer docs to a completely separate file, under a new name
machine.TimerWiPy, it gives a clean slate to define and write the docs for
a better, general machine.Timer class.  This is with the aim of eventually
providing documentation that does not have conditional parts to it,
conditional on the port.

While the new docs are being defined it makes sense to keep the WiPy docs,
since they describe its behaviour.  Once the new Timer behaviour is defined
the WiPy code can be changed to match it, and then the TimerWiPy docs would
be removed.

Damien George 81e320aecc docs/library/machine: Remove conditionals in machine class index.
The machine module should be standard across all ports so should have the
same set of classes in the docs.  A special warning is added to the top of
the machine.SD class because it is not standardised and only available on
the cc3200 port.

Damien George 84d5dd46fe docs/library/index: Remove all conditionals from library index.
It's fair to just provide a link to all available modules, regardless of
the port.  Most of the existing ports (unix, stm32, esp8266, esp32) share
most of the same set of modules anyway, so no need to maintain separate
lists for them.  And there's a big discussion at the start of this index
about modules not being available on a given port.

For port-specific modules, they can also be listed unconditionally because
they have headings that explicitly state they are only available on certain
ports.

Damien George 4cc65e22d4 docs/library/machine.UART: Remove conditional docs for wipy port.
The UART.init() method is now included unconditionally and its wording
adjusted to better describe ports other than the cc3200.

UART.irq() is also included unconditionally, but this is currently only
available on the WiPy target.

Damien George 805fd0cfe6 docs/library: Remove "only" directive from all pyb module docs.
By virtue of its name, the pyb module would only be available on a pyboard
and so does not need to have conditional "only" directives throughout its
documentation.

These conditionals were added mostly in
cfcf47c064 in the initial development of the
cc3200 port, which had the pyb module before it switched to the machine
module.  And wipy only conditionals were removed from the pyb module
documentation in 4542643025, so there's no
need to retain any more conditionals.

Paul Sokolovsky 2e3468a68c docs/usocket: getaddrinfo: Describe af/type/proto optional params.
These can be optionally specified, but all ports are expected to be able to
accept them, at the very least ignore, though handling of "type" param
(SOCK_STREAM vs SOCK_DGRAM) is recommended.
