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.

lukem b234edd83d * Support reading multiple keys with the same name if '-D' is given,
using db->seq() and match comparison rather than db->get().
* Deleting multiple keys of the same name appears to already work as-is
  with a single db->del() call; I had code to implement this if '-D'
  is given but it appears to be unnecessary.
* Cosmetic/KNF tweaks.

lukem 50ec57658e Allow the input [file] field separator to be a string and not just a
single character.
Use argument-specific value names in the usage string & manual page
to simplify searching for the value's use.

the item's size is > 0.

jmmv b635f565e7 Homogenize usage messages: make the 'usage' word all lowercase, as this seems
to be the most common practice in our tree.

seb c4cd748ebd Add option -S to specify strvis(3) encoding of keys and/or values
when reading a database.  Add options -T and -X to tweak encoding.

Add option -U to specify strunvis(3) decoding of keys and/or values
when writing a database or deleting entries from a database.

Kill TODO item 'add option to strunvis(3) key (& value) from infile
?': unvis(1) can be used to achieve that.

Approved by lukem@. And thanks to him for suggestions.
