Implement range-checking in all counts in apps.  Turns out only a couple

Loading the config file after processing command line options can
cause problems, e.g. where an engine provides new ciphers/digests
these are not then recoginised on the command line. Move the
default config file loading to before the command line option
processing. Whilst we're doing this we might as well centralise
this instead of doing it individually for each application. Finally
if we do it before the OpenSSL_add_ssl_algorithms() call then
ciphersuites provided by an engine (e.g. GOST) can be available to
the apps.

To set both the incoming and outgoing data when 'encrypting' or

If the output to stdout or the input from stdin is meant to be binary,
it's deeply unsetting to get the occasional LF converted to CRLF or
the other way around.  If someone happens to forget to redirect stdin
or stdout, they will get gibberish anyway, line ending conversion will
not change that.

Therefore, let's not have dup_bio_* decide unilaterally what mode the
BIO derived from stdin and stdout, and rather let the app decide by
declaring the intended format.

The different apps had the liberty to decide whether they would open their
input and output files in binary mode or not, which could be confusing if
two different apps were handling the same type of file in different ways.

The solution is to centralise the decision of low level file organisation,
and that the apps would use a selection of formats to state the intent of
the file.

clang suggests %llu instead, but it isn't clear that is portable on
all platforms.

C99 and above define a handy macro for us, so we try to use that
definition and fall back to current definition if needed (though we
switch to 'u' for unsigned).

Here are the "rules" for handling flags that depend on #ifdef:

- Do not ifdef the enum.  Only ifdef the OPTIONS table.  All ifdef'd
  entries appear at the end; by convention "engine" is last.  This
  ensures that at run-time, the flag will never be recognized/allowed.
  The next two bullets entries are for silencing compiler warnings:
- In the while/switch parsing statement, use #ifdef for the body to
  disable it; leave the "case OPT_xxx:" and "break" statements outside
  the ifdef/ifndef.  See ciphers.c for example.
- If there are multiple options controlled by a single guard, OPT_FOO,
  OPT_BAR, etc., put a an #ifdef around the set, and then do "#else"
  and a series of case labels and a break. See OPENSSL_NO_AES in cms.c
  for example.

RT2943 only complains about the incorrect check of -K argument size,
we might as well do the same thing with the -iv argument.

Before this, we only checked that the given argument wouldn't give a
bitstring larger than EVP_MAX_KEY_LENGTH.  we can be more precise and
check against the size of the actual cipher used.

This is merges the old "rsalz-monolith" branch over to master.  The biggest
change is that option parsing switch from cascasding 'else if strcmp("-foo")'
to a utility routine and somethin akin to getopt.  Also, an error in the
command line no longer prints the full summary; use -help (or --help :)
for that.  There have been many other changes and code-cleanup, see
bullet list below.

Special thanks to Matt for the long and detailed code review.
