Namespaced the generated headers with `zephyr` to prevent potential conflict with other headers. Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH` that is enabled by default. This allows the developers to continue the use of the old include paths for the time being until it is deprecated and eventually removed. The Kconfig will generate a build-time warning message, similar to the `CONFIG_TIMER_RANDOM_GENERATOR`. Updated the includes path of in-tree sources accordingly. Most of the changes here are scripted, check the PR for more info. Signed-off-by: Yong Cong Sin <ycsin@meta.com> |

.. _posix-env-sample: POSIX Environment Variables ########################### Overview ******** In this sample application, the POSIX :c:func:`setenv`, function is used to populate several environment variables in C. Then, all environment variables are then printed. If the user sets a new value for the ``ALERT`` environment variable, it is printed to standard output, and then cleared via :c:func:`unsetenv`. Building and Running ******************** This project outputs to the console. It can be built and executed on QEMU as follows: .. zephyr-app-commands:: :zephyr-app: samples/posix/env :host-os: unix :board: qemu_riscv32 :goals: run :compact: Sample Output ============= The program below shows sample output for a specific Zephyr build. .. code-block:: console BOARD=qemu_riscv32 BUILD_VERSION=zephyr-v3.5.0-5372-g3a46f2d052c7 ALERT= Setting Environment Variables ============================= The shell command below shows how to create a new environment variable or update the value associated with an existing environment variable. The C code that is part of this sample application displays the value associated with the ``ALERT`` environment variable and then immediately unsets it. .. code-block:: console uart:~$ posix env set ALERT="Happy Friday!" uart:~$ ALERT="Happy Friday!" uart:~$ posix env set HOME="127.0.0.1" uart:~$ Getting Environment Variables ============================= The shell command below may be used to display the value associated with one environment variable. .. code-block:: console uart:~$ posix env get BOARD qemu_riscv32 The shell command below may be used to display all environment variables and their associated values. .. code-block:: console uart:~$ posix env get BOARD=qemu_riscv32 BUILD_VERSION=zephyr-v3.5.0-5372-g3a46f2d052c7 ALERT= Unsetting Environment Variables =============================== The shell command below may be used to unset environment variables. .. code-block:: console uart:~$ posix env unset BOARD
