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.

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.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.
