In older distros we need bsd/stdlib.h but newer distro doesn't
need it. Also old distro will need libbsd-devel installed and newer
doesn't. To remove a possible dependency on libbsd-devel replace usage
of reallocarray to realloc.
dcb_app.c: In function ‘dcb_app_table_push’:
dcb_app.c:68:25: warning: implicit declaration of function ‘reallocarray’; did you mean ‘realloc’?

DCB APP interfaces are standardized in 802.1q-2018, and allow configuration
of traffic prioritization rules based on several possible headers.
Add a dcb subtool for maintenance and display of the APP table. For
example:
# dcb app add dev eni1np1 dscp-prio 0:0 CS3:3 CS6:6
# dcb app show dev eni1np1
dscp-prio 0:0 CS3:3 CS6:6
# dcb app add dev eni1np1 dscp-prio CS3:4
# dcb app show dev eni1np1
dscp-prio 0:0 CS3:3 CS3:4 CS6:6
# dcb app replace dev eni1np1 dscp-prio CS3:5
# dcb app show dev eni1np1
dscp-prio 0:0 CS3:5 CS6:6
