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.

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.

record-oriented fashion.  That means that every write() will write a
separate record, which will be read separately by the programs trying
to read from it.  This can be very confusing.

The solution is to put a BIO filter in the way that will buffer text
until a linefeed is reached, and then write everything a line at a
time, so every record written will be an actual line, not chunks of
lines and not (usually doesn't happen, but I've seen it once) several
lines in one record.  Voila, BIO_f_linebuffer() is born.

Since we're so close to release time, I'm making this VMS-only for
now, just to make sure no code is needlessly broken by this.  After
the release, this BIO method will be enabled on all other platforms as
well.
