* include/abg-libxml-utils.h (new_reader_from_istream): Declare
new public entry point.
* src/abg-libxml-utils.cc (xml_istream_input_read)
(xml_istream_input_close): New static functions.
(new_reader_from_istream): Define new public input function.
* include/abg-reader.h (read_translation_unit_from_istream):
Declare new entry points.
* src/abg-reader.cc (read_translation_unit_from_istream): Define
new entry points.
* tools/bilint.cc (options::{read_from_stdin, noout}): New
members.
(display_usage): Document --stdin and --noout.
(parse_command_line): Adjust to consider that no option on the
command line means reading from stdin, just like --stdin. Support
the --noout option as well.
(main): Support Read the abi instr from stdin; in that case, what
was read is just serialized back to stdout, unless --noout was
supplied.
