721728e7de Support reading and comparing soname from ELF files
Libabigail's DWARF reader doesn't read the DT_SONAME tag from the
.dynamic section.  The abigail::corpus type doesn't have a property
for that tag either.  And the comparison engine doesn't take that tag
in when comparing corpora.

This patch modifies the DWARF reader to read the DT_SONAME and
DT_NEEDED tags from the .dynamic section.  The value of DT_SONAME tag
is then saved in the new corpus property accessed by the new
abigail::corpus::get_soname() accessor.  The comparison engine has
also been modified to compare the sonames of two corpora being
compared.  Note that the value of the DT_NEEDED elf tag is saved in a
new corpus property that is accessed via the new
abigail::corpus::get_needed() getter.  This property is not used yet.

This patch also adds a unit test for this new feature.

ef7e71febf Initial implementation of the abicompat tool
Given an application A that links to a shared library L of version V
denoted L(V) and a subsequent version of that library denoted L(V+P),
the 'abicompat' tool tells the user if L(V+P) is still ABI compatible
with L(V+P).  And if it is not, abicompat gives a reports that shows
the differences between L(V) and L(V+P) that makes L(V+P)
ABI-incompatible with A.

The source code of this tool is in the tools/abicompat.cc source
file.  To support this new tool, this commit changes the comparison
engine to optionally avoid showing added symbols that were not
referenced by any debug info.  It changes the ABI corpus type to allow
the specification of a list of variables and functions symbols to keep
(and drop all other functions and variables which have other symbols
on the floor even before starting to compare the two libraries).

This is how the abicompat tool itself works.  It basically compares
L(V) and L(V+P) but it only looks at their exported functions and
variables which symbols are undefined in application A.  If the list
of exported and defined variables and functions of L(V) whose symbols
are undefined in A equals that of L(V+P) (including the sub-types of
these variables and functions) A is still compatible with L(V+P).
Otherwise, they might not be compatible depending on the kind of
differences that are found.

06279598c8 Support reading undefined symbols from an ELF file
In preparation to support the upcoming 'abicompat' tool, we need the
ABI corpus type to capture the symbols that are undefined in a given
ELF file.

This patch changes the ELF reader to capture the undefined symbols as
well as the symbol versions they need to be satisfied.  These
undefined symbols are then stored in the instance ABI corpus build as
a result of the reading of the ELF file.

At the moment, these undefined symbols are not serialized to the
native XML format of libabigail yet.  I guess I'll do that in a
subsequent patch.

	set_undefined_var_symbol_map, get_undefined_fun_symbol_map_sptr,
	get_undefined_fun_symbol_map, get_sorted_undefined_fun_symbols,

	we want the definition version or the needed version of a symbol.
	Extend the implementation using the two new function
	get_version_needed_for_versym() and

	returns the version either for a defined & exported symbol, or for
	an undefined symbol.

6d5f7c1223 Move location, location_manager & translation_unit back into abg-ir.h
* include/abg-corpus.h: Move location location_manager,
	translation_unit from here ...
	* include/abg-ir.h: ... to here.  The reason being that these are
	really constructs of the Internal Representation of the ABI/API of
	a translation unit.  What is left in abg-corpus is really
	exclusively related to an ABI Corpus, which I see more as a
	"packaging" construct that abstracts the bundling of several
	translation units together.  Also, I fixed some comments about the
	location/location_manger types; now a location is made specific to
	a translation unit; to an abi corpus.  A location of a given
	translation unit has to be decoded by the location manager of that
	same translation unit.
