This adds support for reading the "bigobj" variant of COFF produced by cl's /bigobj and mingw's -mbig-obj. The most significant difference that bigobj brings is more than 2**16 sections to COFF. bigobj brings a few interesting differences with it: - It doesn't have a Characteristics field in the file header. - It doesn't have a SizeOfOptionalHeader field in the file header (it's only used in executable files). - Auxiliary symbol records have the same width as a symbol table entry. Since symbol table entries are bigger, so are auxiliary symbol records. Write support will come soon.
