Reto Schneider 7eabab2f5d samples, tests: Use semi-accurate project names
When using an IDE (e.g. Eclipse, Qt Creator), the project name gets
displayed. This greatly simplifies the navigation between projects when
having many of them open at the same time. Naming every project "NONE"
defeats this functionality.

This patch tries to use sensible project names while not duplicating
too much of what is already represented in the path. This is done by
using the name of the directory the relevant CMakeLists.txt file is
stored in. To ensure unique project names in the samples (and again, in
the tests folder) folder, small manual adjustments have been done.

console_getline() Sample Application
####################################

Overview
********

This example shows how to use :cpp:func:`console_getline()` function.
Similar to the well-known ANSI C gets() and fgets() functions,
:cpp:func:`console_getline()` either returns the next available input
line or blocks waiting for one. Using this function, it should be fairly
easy to port existing ANSI C, POSIX, or Linux applications which process
console input line by line. The sample also allows to see details of how
a line is returned by the function.

If you are interested in character by character console input, see
:ref:`console_getchar_sample`.


Requirements
************

UART console is required to run this simple.


Building and Running
********************

The easiest way to run this sample is using QEMU:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/console/getline
   :host-os: unix
   :board: qemu_x86
   :goals: run
   :compact:

Now start pressing keys on a keyboard, followed by Enter. The input line
will be printed back, with a hex code of the last character, to show that
line does not include any special "end of line" characters (like LF, CR,
etc.)
