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.

Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in

bfd_bread and bfd_bwrite.

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}_*)

Define bfd_find_line entry of BFD_JUMP_TABLE_SYMBOLS using NAME.
In https://www.sourceware.org/ml/binutils/2005-06/msg00082.html
HJ implemented bfd_find_line for DWARF2, but cheated a little in not
using the usual NAME##_find_line, saving quite a lot of boring
editing. However that shortcut probably contributed to
bfd_find_nearest_line_discriminator being implemented the same way,
and missing support for some targets.

Rewrite __start and __stop symbol handling
This arranges for __start and __stop symbols to be defined before
garbage collection, for all target formats. That should allow the
COFF and PE --gc-sections to keep a singleton orphan input section,
a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF
treatment of keeping all input sections associated with a __start or
__stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained.
.startof. and .sizeof. symbols are deliberately not defined before
garbage collection, so these won't affect garbage collection of
sections.
The patch also ensures __start, __stop, .startof. and .sizeof. symbols
are defined before target size_dynamic_sections is called, albeit
with a preliminary value, so that target code doesn't need to cope
with a symbol changing from undefined at size_dynamic_sections to
defined at relocate_section.
Also, a number of problems with the testcases have been fixed.
