The DWARF reader is no longer the only ELF-based reader in libabigail:
the CTF reader also operates on ELF files. Other ELF-based formats
(such as BTF) may also join in the future. These readers share a lot
of similarities: they all operate on object files, they fetch
debugging information from certain sections, they rely on the symtab
of the read object, the debugging info may be in a separated file (for
certain formats) and so on.
It follows that a lot of logic can be shared among all the ELF-based
readers. This patch is oriented to that direction.
A new namespace, abigail::elf_reader, is introduced with the goal of
holding features and definitions useful for any ELF-based abigail
reader. Then all the definitions related to the status resulting from
extracting a corpus from an object file (the dwarf_reader::status) are
moved to abigail::elf_reader. The utilities and tests are adjusted
accordingly.
