[dpdk-dev] [PATCH v2 1/4] doc: remove outdated guidelines for library addition

[Thomas Monjalon]

There was a doc about how to extend DPDK by adding a library.
It could have been useful but was never updated,
so it is lacking a lot of explanations about doxygen,
meson, versioning, maintainership, etc.

Anyway such guidelines should fit in the contributors guide.
Better to completely remove this obsolete document.

-Extending the DPDK
-=========================
-
-This chapter describes how a developer can extend the DPDK to provide a new library,
-a new target, or support a new target.
-
-Example: Adding a New Library libfoo
-------------------------------------
-
-To add a new library to the DPDK, proceed as follows:
-
-#. Add a new configuration option:
-
-   .. code-block:: bash
-
-        for f in config/\*; do \
-            echo CONFIG_RTE_LIBFOO=y >> $f; done
-
-#. Create a new directory with sources:
-
-   .. code-block:: console
-
-        mkdir ${RTE_SDK}/lib/libfoo
-        touch ${RTE_SDK}/lib/libfoo/foo.c
-        touch ${RTE_SDK}/lib/libfoo/foo.h
-
-#. Add a foo() function in libfoo.
-
-    Definition is in foo.c:
-
-    .. code-block:: c
-
-        void foo(void)
-        {
-        }
-
-    Declaration is in foo.h:
-
-    .. code-block:: c
-
-        extern void foo(void);
-
-
-#. Update lib/Makefile:
-
-    .. code-block:: console
-
-        vi ${RTE_SDK}/lib/Makefile
-        # add:
-        # DIRS-$(CONFIG_RTE_LIBFOO) += libfoo
-
-#. Create a new Makefile for this library, for example, derived from mempool Makefile:
-
-    .. code-block:: console
-
-        cp ${RTE_SDK}/lib/librte_mempool/Makefile ${RTE_SDK}/lib/libfoo/
-
-        vi ${RTE_SDK}/lib/libfoo/Makefile
-        # replace:
-        # librte_mempool -> libfoo
-        # rte_mempool -> foo
-
-
-#. Update mk/DPDK.app.mk, and add -lfoo in LDLIBS variable when the option is enabled.
-   This will automatically add this flag when linking a DPDK application.
-
-
-#. Build the DPDK with the new library (we only show a specific target here):
-
-    .. code-block:: console
-
-        cd ${RTE_SDK}
-        make config T=x86_64-native-linux-gcc
-        make
-
-
-#. Check that the library is installed:
-
-    .. code-block:: console
-
-        ls build/lib
-        ls build/include
-
-Example: Using libfoo in the Test Application
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The test application is used to validate all functionality of the DPDK.
-Once you have added a library, a new test case should be added in the test application.
-
-*   A new test_foo.c file should be added, that includes foo.h and calls the foo() function from test_foo().
-    When the test passes, the test_foo() function should return 0.
-
-*   Makefile, test.h and commands.c must be updated also, to handle the new test case.
-
-*   Test report generation: autotest.py is a script that is used to generate the test report that is available in the
-    ${RTE_SDK}/doc/rst/test_report/autotests directory. This script must be updated also.
-    If libfoo is in a new test family, the links in ${RTE_SDK}/doc/rst/test_report/test_report.rst must be updated.
-
-*   Build the DPDK with the updated test application (we only show a specific target here):
-
-
-    .. code-block:: console
-
-        cd ${RTE_SDK}
-        make config T=x86_64-native-linux-gcc
-        make
