use abstracted bit count functions

Now that DPDK provides such bit count functions, make use of them.

This patch was prepared with a "brutal" commandline:

use abstracted bit count functions

Now that DPDK provides such bit count functions, make use of them.

This patch was prepared with a "brutal" commandline:

$ old=__builtin_clzll; new=rte_clz64;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"
$ old=__builtin_clz; new=rte_clz32;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"

$ old=__builtin_ctzll; new=rte_ctz64;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"
$ old=__builtin_ctz; new=rte_ctz32;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"

$ old=__builtin_popcountll; new=rte_popcount64;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"
$ old=__builtin_popcount; new=rte_popcount32;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"

Then inclusion of rte_bitops.h was added were necessary.
