[PATCH v2 00/23] examples: fix -Wshadow warnings

[Stephen Hemminger <stephen@networkplumber.org>]

Several DPDK examples had -Wshadow disabled via no_shadow_cflag in
their meson.build files. This series fixes all shadow variable
warnings and removes the suppression flag, so that -Wshadow is
enabled uniformly across every example.

The fixes fall into three categories:
 - Renaming function parameters or local variables that shadow
   globals (most patches)
 - Removing unused function parameters that duplicated globals
   (dma, bond, flow_filtering, ipsec-secgw, vhost, qos_sched)
 - Simply removing no_shadow_cflag where there were no warnings
   (vm_power_manage, bbdev_app, l2fwd-crypto, l2fwd-event,
   l3fwd-graph)

v2 - fix additional shadow warnings only visible with clang
