2824b29025 Bug 895322 - Part 1: Replace the usages of MOZ_STATIC_ASSERT with C++11 static_assert; r=Waldo 
This patch was mostly generated by running the following scripts on the codebase, with some
manual changes made afterwards:

# static_assert.sh
#!/bin/bash
# Command to convert an NSPR integer type to the equivalent standard integer type

function convert() {
echo "Converting $1 to $2..."
find . ! -wholename "*nsprpub*" \
       ! -wholename "*security/nss*" \
       ! -wholename "*/.hg*" \
       ! -wholename "obj-ff-dbg*" \
       ! -name nsXPCOMCID.h \
       ! -name prtypes.h \
         -type f \
      \( -iname "*.cpp" \
         -o -iname "*.h" \
         -o -iname "*.cc" \
         -o -iname "*.mm" \) | \
    xargs -n 1 `dirname $0`/assert_replacer.py #sed -i -e "s/\b$1\b/$2/g"
}

40a94b7921 Remove some extraneous includes and a function, all added in bug 714260. They were initially necessary when that patch was written, but they became vestigial during rebasing prior to landing, and this disuse wasn't noticed til now. r=lumpy 2012-04-19 16:36:31 -07:00
