remove instances of CALL

[MichaelRawson]

In #412 we removed the need for CALL macros, but didn't actually remove them to facilitate easy code review. This actually removes them.

This was done mostly automatically with the following AWK script to conservatively remove CALL macros followed by any number of trailing blank lines:

BEGIN {
  trailing = 0
}

/^[[:space:]]*CALL *\( *".*" *\)( *;)* *$/ {
  trailing = 1
  next
}

/^[[:space:]]*$/ {
  if(!trailing) print $0
  next
}

{
  trailing = 0
  print $0
}

People with branches might want to apply the following one-liner to new files in their branches to get the same effect, although it's probably easier to merge/rebase/cherry-pick for existing files.

for file in `git ls-files | egrep '\.(hpp|cpp|c|h|cc)$'`; do echo $file; awk 'BEGIN {trailing=0}; /^[[:space:]]*CALL *\( *".*" *\)( *;)* *$/ { trailing=1; next } /^[[:space:]]*$/ { if(!trailing) print $0; next } { trailing=0; print $0 }' $file > /tmp/out; mv /tmp/out $file; done

I then manually cleaned up some awkward cases, deleted the macro definitions, and removed most includes of Debug/Tracer.hpp.
