Dodji Seketeli bac732ff5a Add --drop/--keep options to bidiff
* include/abg-sptr-utils.h: New file.
	* include/Makefile.am: Add abg-sptr-utils. to the build system.
	* include/abg-libxml-utils.h (reader_sptr, xml_char_sptr): Remove
	these typedefs as there are now in abg-sptr-utils.
	(build_sptr): Likewise for this template and its specializations
	declarations.
	* src/abg-libxml-utils.cc (sptr_utils::build_sptr): Mode the
	definition of the specializations for xmlTextReader and xmlChar
	into the sptr_utils namespace.
	* include/abg-corpus.h
	(corpus::{get_regex_patterns_of_fns_to_suppress,
	get_regex_patterns_of_vars_to_suppress,
	get_regex_patterns_of_fns_to_keep,
	get_regex_patterns_of_vars_to_keep}): Declare new member
	functions.
	* src/abg-comparison.cc (sptr_utils::regex_t_deleter): Define new
	functor.
	(build_sptr) Define new specialization for regex_t.
	(struct array_deleter): Remove unused functor.
	(corpus::priv::regex_patterns_{fns,vars}_to_{suppress,keep}): New data
	members.
	(symtab_build_visitor_type::regex_patterns_{fns,vars}_to_{suppress,keep}):
	Likewise.
	(symtab_build_visitor_type::r_{fns,vars}_{suppress,keep})):
	Likewise.
	(symtab_build_visitor_type::symtab_build_visitor_type): Update the
	signature of this constructor to take regex patterns for functions
	and variables to suppress and to keep.  Also, initialize the data
	members from these new parameters.
	(symtab_build_visitor_type::regex_{fns,vars}_{suppress,keep}): New
	member functions.
	(symtab_build_visitor_type::{add_fn_to_wip_fns,
	add_var_to_wip_vars}): Likewise.
	(symtab_build_visitor_type::visit) Use either add_fn_to_wip_fns or
	add_var_to_wip_vars depending on the overload of the visit()
	member.
	(corpus::priv::build_symbol_table): Update for the change of the
	symtab_build_visitor_type constructor signature.
	(corpus::get_regex_patterns_of_{fns,vars}_to_{suppress,keep}):
	Define new member functions.
	* tools/bidiff.cc (options::{drop,keep}_{fn,var}_regex_patterns}):
	New data member.
	(display_usage): Add help strings for --drop, --drop-fn,
	--drop-var, --keep, --keep-fn, --keep-var
	(parse_command_line): Parse the command lines above.
	(set_corpus_keep_drop_regex_patterns): Define new static function.
	(main): Use the new set_corpus_keep_drop_regex_patterns.
