[PATCH] Fix merge-by-content to not merge atoms with different custom sections

[kledzik at apple.com]

Hi ruiu, t.p.northover, shankar.easwaran,

The mergeByContent attribute on atoms triggers the symbol table to coalesce atoms with the exact same content.  The problem is that atoms can also have a required custom section.  The coalescing should never change the custom section of an atom.  

The fix is to only consider to atoms to have the same content if their sectionChoice() and customSectionName() attributes match.
