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.

going from:

This is because we choose to insert "reset -" before the current line,

cleareol code did not handle this case properly; we now cleareol to
the maximum number of characters of the first difference, the second
difference and the difference in line length.

3cfbfdb2ef Bug reported from Martin Dietze: 
The place to change the completion_append_character is
    usually somewhere in the `rl_completion_entry_function'
    callback which is where one usually can distinguish between
    file- or dir-like entries to append a slash for dirs etc.

    This does no longer work since `fn_complete()' takes the
    `append_character' as argument before the callback is executed,
    so that changes to the variable `rl_completion_append_character'
    have in fact no effect for the current completion.

Fix by adding a function that returns the rl_completion_append_character,
when it gets passed in a filename in readline emulation.

917b5f36b1 PR/25694: Luke Mewburn: Don't abuse unconstify'ing a string and writing to 
it, because you'll core dump. Also remove extra const that gives pain to
the irix compiler.

26abf58dee Sync the alternative readline interface with reality: 
+ the rl_callback_handler_install takes a pointer to a void function
  which has one char * argument (it's called that way in the readline
  emulation source, otherwise there's no way to pass the line buffer
  to the function which processes the line when EOL is encountered)

+ provide a prototype for that function signature and use it

Makes the callback readline interface work now.

41a59814ed Separate out the filename completion functions from the readline() code. 
Pass in loads of parameters instead of relying on shed-loads of global
variables to modify the behaviour.
The filename completion code can now be enabled by code that uses el_gets().
