Anas Nashif 52b3d2b671 cleanup: include/: move tty.h to console/tty.h
move tty.h to console/tty.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Paul Sokolovsky 0925411356 tty: Remove buffer params from tty_init()
Let's have more orthogonal and cleaner API, where buffers are
configured by tty_set_rx_buf/tty_set_tx_buf, and only them. It
means that newly initialized tty starts in unbuffered mode, which
is somewhat a sidestep from a main usecase behind tty, which is
buffered operation, but again, having a cleaner API (and good
docs, explaining users how it should be and what they should do)
prevails.

Paul Sokolovsky ed852e8b4a subsys: console: Split tty definitions into tty.h, to form its own API
This patch proceeds with the separation of older serial console
subsystem into device-independent console subsytem and buffered
serial device ("tty") API.

Paul Sokolovsky 6203020bfd subsys: console: Switch to POSIX-like read/write interface
Tty device gets only read/write calls, but console retains
getchar/putchar for convenience.

Paul Sokolovsky 680085b3e2 subsys: console: tty: Allow to specify receive timeout
This allows to specify receive timeout, instead of previously
hardcoded K_FOREVER value. K_FOREVER is still the default, and can
be changes after tty initialization using tty_set_rx_timeout() call,
and timeout is stored as a property of tty. (Instead of e.g. being
a param of each receive call. Handling like that is required for
POSIX-like behavior of tty).

Paul Sokolovsky ca8aea1a62 subsys: console: Split serial tty handling to a separate module
Before going further for API refactoring in console subsys, makes
sense to split "tty" implementation from "console" implementation,
to make it clearer that "console" is just a "tty" instantiated on
a particular UART device.

Paul Sokolovsky 95b64fb776 subsys: console: Refactor code to allow per-UART "tty" wrapper
Instead of having just one static "UART console" device, allow to
instantiate buffered, interrupt-driven POSIX-like "tty" wrapper for
any underlying device. Then, use this functionality to provide
compatible "console API".

Paul Sokolovsky c524ff6b8c subsys: console: getchar: Use consistent var names for RX path
Initially, there was support only for buffered input, and adhoc var
names used. Later, buffered output support was added, with variables
consistently using "tx_" prefix. Now, rename the original RX path
to use symmetric "rx_" prefix.

Johan Hedberg 253a7f7064 Revert "subsys/console: Yield on char availability."
This reverts commit 4e2eaec268.

It's invalid to call k_yield from ISR. In fact, it'll trigger an
__ASSERT.

Paul Sokolovsky 4e2eaec268 subsys/console: Yield on char availability.
If this is not done, there is common pattern that on big input block
(e.g. from a clipboard paste), IRQ routine is called in a tight loop,
leading to circular buffer overflow.

Paul Sokolovsky 542c2b93d0 subsys: console: Add pull-style console API support.
This change introduces console_getchar() and console_getline() API
calls which can be used to get pending console input (either one
char or whole line), or block waiting for one. In this regard, they
are similar to well-known ANSI C function getchar/gets/fgets, and
are intended to ease porting of existing applications to Zephyr, and
indeed, these functions (shaped as an external module) are already
used by few applications.

The implementation of the functions is structured as a new "console"
subsystem. The intention is that further generic console code may be
pulled there instead of being in drivers/console/. Besides the
functions themselves, initialization code and sample applications
are included.

At this time, there're may limitations of how these functions can
be used. For example, console_getchar() and console_getline() are
mutually exclusive, and both are incompatible with callback
(push-style) console API (and e.g. with console shell subsystem
which uses this API). Again, the intention is to make a first step
towards refactoring console subsystem to allow more flexible
real-world usage, better reusability and composability.
