[PATCH v1 00/14] Several clean-ups and refactorings before a long patch series on AArch64 build attributes

[Matthieu Longo]

This patch series contains clean-ups and refactorings required for a future patch series implementing AArch64 AEABI build attributes.

## Space fixes:
clean-up: fix annoying spaces in binutils/readelf.c
clean-up: fix conflicting symbol with unknown from bfd/elf-bfd.h

## Improve code readability
clean-up bfd/elf-attrs.c: change return type of uleb128_size to unsigned
clean-up readelf: simplify and flatten body of process_attributes
clean-up: move writing of build attributes section into a function
refactoring bfd_linear_search_one_with_gnu_property
refactoring _bfd_elf_get_property
refactoring elf_find_and_remove_property

## Clarifications:
clean-up create_obj_attrs_section: comment about .gnu.attributes VS .gnu.build.attributes

## Configuration reusability:
clean-up aarch64: move the name of the build attributes section into include/elf/aarch64.h

## Prepare object attributes v2 (based on AArch64 AEABI build attributes specifications)
clean-up bfd: rename functions for object attributes v1
clean-up bfd/elf-attrs.c: move specific-code to parse object attributes v1 into a new function

## Fix logic
aarch64: setup_gnu_properties only creates the notes section when none exists


Regression tested on aarch64-unknown-linux-gnu, and no regression found.

Ok for binutils-master ?

Regards,
Matthieu.
