bts: Drop specific functions to increase counters

It's super annoying seeing lots of functions being called everywhere
only to find out they are only incrementing a counter. Let's drop all
those functions and increment the counter so people looking at code
doesn't see dozens of code paths evyerwhere.

Most of the commit was generated by following sh snippet:
"""
 #!/bin/bash
grep -r -l ^CREATE_COUNT_INLINE . | xargs cat | grep "^CREATE_COUNT_INLINE("| tr -d ",;" | tr "()" " " | awk '{ print $2 " " $3 }' >/tmp/hello

while read -r func_name ctr_name
do
 #echo "$func_name -> $ctr_name"
files="$(grep -r -l "${func_name}()" .)"
for f in $files; do
echo "$f: $func_name -> $ctr_name";
sed -i "s#${func_name}()#do_rate_ctr_inc(${ctr_name})#g" $f
done;
done < /tmp/hello

grep -r -l "void do_rate_ctr_inc" | xargs sed -i "/void do_rate_ctr_inc(CTR/d"
grep -r -l "CREATE_COUNT_INLINE" | xargs sed -i "/^CREATE_COUNT_INLINE/d"
"""
