joerg 5df6c2ea3b Format the diagnostic with vasprintf once and use plain syslog instead 
of messing with format strings.

tls 4147a3c54a Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the 
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry.  RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros.  Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default.  Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

mrg 0c37c63edc change (mostly) int to socklen_t. GCC 4 doesn't like that int and 
socklen_t are different signness.

lukem 0beaa38406 If we're going to replace strtok() with strtok_r(), and the caller of the 
latter is invoked recursively, use static (instead of automatic) storage

thorpej 9c33b55e7c Split the notion of building Hesiod, Kerberos, S/key, and YP 
infrastructure and using that infrastructure in programs.

	* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
	  of the infratsructure (libraries, support programs, etc.)

	* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
	  building of support for using the corresponding API
	  in various libraries/programs that can use it.

As discussed on tech-toolchain.
