dc810e3900 Touches most files in bfd/, so likely will be blamed for everything..
o  bfd_read and bfd_write lose an unnecessary param and become
   bfd_bread and bfd_bwrite.

o  bfd_*alloc now all take a bfd_size_type arg, and will error if
   size_t is too small.  eg. 32 bit host, 64 bit bfd, verrry big files
   or bugs in linker scripts etc.

o  file_ptr becomes a bfd_signed_vma.  Besides matching sizes with
   various other types involved in handling sections, this should make
   it easier for bfd to support a 64 bit off_t on 32 bit hosts that
   provide it.

o  I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
   generally available.  They now cast their args to bfd_vma and
   bfd_byte * as appropriate, which removes a swag of casts from the
   source.

o  Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
   aout-encap.c.

o  Zillions of formatting and -Wconversion fixes.

        (decode_line_info): Don't try to infer lo_pc and hi_pc from the
        debug-line info---it doesn't work right if a compilation unit
        consists of multiple discontiguous code-sequences.  It would be
        worthwhile to optimize for the common case where a compilation

        (lookup_address_in_line_info_table): Don't use the last line entry
        for a compilation unit for anything with an address higher than
        this line entry.  Also, check for end_sequence markers to
        correctly handle discontinuities.
        (_bfd_dwarf2_find_nearest_line): When checking previously loaded

        just like when reading compilation units.
        * dwarf2.c (decode_line_info): Initialize table->files and

        values in these members.
        (concat_filename): Check for out-of-range file number before
        indexing filename table.  Segfaults suck.
        * dwarf2.c (decode_line_info): Don't truncate address to least
        significant 32 bits (breaks 64 bit targets).
