[PATCH v1 00/24] Migrate threads to the DPDK service framework and refactor naming for exported symbols

This modification provides better resource (CPU) management for NTNIC PMD.

The following threads are migrated:
        * FLM update thread
        * Statistic thread
        * Port event thread
        * Adapter monitoring thread
Additionally, a warning is added to inform users about the importance of
dedicating lcores to the DPDK service framework when using the NTNIC PMD.
The code is also cleaned up to use pthreads and rte_thread APIs.

After this patch series, an each application using NTNIC PMD should
dedicate at least five(5) cores for DPDK service framework to ensure
proper operation of the NTNIC PMD.

The service cores can be dedicated by EAL options:
        * s SERVICE COREMASK Hexadecimal bitmask of cores to be used as service cores
        * S SERVICE CORELIST List of cores to run services on
Or with a special API by the application itself.
        * rte_pmd_ntnic_service_set_lcore to map a service to a specific lcore
        * rte_pmd_ntnic_service_get_id to get a service ID.

This patch series also includes aligning the naming of the exported symbols to avoid
potential conflicts with other applications and libraries.
The main change is to add the prefix "nthw_".
