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.

        in _any_ of the address ranges associated with a compilation unit.
        (_bfd_dwarf2_find_nearest_line): Call comp_unit_find_nearest_line
        on the first comp_unit that contains the address.

* dwarf2.c (struct line_info): Add member END_SEQUENCE to keep
        track of end_sequence markers.
        (add_line_info): Add END_SEQUENCE arg.
        (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
        unit results in a contiguous set of code sequences, but this is
        quite tricky to get right for arbitrary DWARF2 files.
        (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
        compilation units, check all compilation units with each->high==0
        just like when reading compilation units.
        * dwarf2.c (decode_line_info): Initialize table->files and
        table->last_line to NULL to avoid segfaults due to random
        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).
        (lookup_address_in_function_table): Ditto.
        (comp_unit_contains_address): Ditto.

        assignment from "unsigned char *" to "char *".
