Dodji Seketeli c57e950ec7 Initial writing/reading of an ABI corpus to an archive
* configure.ac: Support detection of libzip dependency. Define
        new DEPS_CFLAGS and DEPS_LIBS variables for use in
        Makefile.am to refer to the dependency headers and
        libraries.
	* doc/website/mainpage.txt: Update this to talk about the new
	libzip dependency.
	* include/Makefile.am: Add abg-libzip-utils.h to the build system.
	* include/abg-corpus.h (corps): Hide abigail::corpus's private behind a
	pimpl idiom.
	(corpus::{drop_translation_units, get_file_path, set_file_path,
	write, read}): New methods.
	* include/abg-libxml-utils.h (new_reader_from_buffer): Declare new
	function.
	* include/abg-libzip-utils.h: New file.
	* src/Makefile.am: Add abg-corpus.cc and abg-libzip-utils.cc to
	the build system.  Refer to the library and headers dependencies
	via the new DEPS_LIBS and DEPS_CFLAGS variables.
	* src/abg-corpus.cc: New file.
	* src/abg-ir.cc (translation::set_path): New method.
	* src/abg-libxml-utils.cc (new_reader_from_buffer): Define new
	function.
	* src/abg-libzip-utils.cc: New file.
	* src/abg-reader.cc (translation_unit::read): New overload.
	* src/abg-writer.cc: Inject the names from the std namespace into
	the abigail namespace, rather than into abigail::writer.
	(abigail::translation_unit::write): New overload.  This can now
	use ofstream and the other stuff from std that are injected in the
	abigail:: namespace.
	* tests/Makefile.am: Add tests/test-write-read-archive.cc to the
	build system; use that to build runtestwritereadarchive.  Also add
	the input test data from
	tests/data/test-write-read-archive/test[0-4].xml.
	* /tests/data/test-write-read-archive/test[0-4].xml: New test
	input data files.
	* tests/test-write-read-archive.cc: New test for this archive
	write/read support.
