Ehsan Akhgari b6e35bb4b4 Bug 1118486 - Part 1: Use = delete instead of MOZ_DELETE directly; r=Waldo
Most of this patch (with the exception of dom/bindings/Codegen.py) was
generated by the following bash script:

#!/bin/bash

function convert() {
echo "Converting $1 to $2..."
find . ! -wholename "*nsprpub*" \
       ! -wholename "*security/nss*" \
       ! -wholename "*/.hg*" \
       ! -wholename "*/.git*" \
       ! -wholename "obj-*" \
         -type f \
      \( -iname "*.cpp" \
         -o -iname "*.h" \
         -o -iname "*.cc" \
         -o -iname "*.idl" \
         -o -iname "*.ipdl" \
         -o -iname "*.ipdlh" \
         -o -iname "*.mm" \) | \
    xargs -n 1 sed -i -e "s/\b$1\b/$2/g"
}

convert MOZ_DELETE '= delete'
