Configure: ensure that a DEPEND generates the correct inclusion directory

For example, if apps/build.info has this:

    SOURCE[footest]=../apps/foo.c

Revert BN_copy() flag copy semantics change

Commit 9f9442918a changed the semantics of BN_copy() to additionally
copy the BN_FLG_CONSTTIME flag if it is set. This turns out to be
ill advised as it has unintended consequences. For example calling
BN_mod_inverse_no_branch() can sometimes return a result with the flag
set and sometimes not as a result. This can lead to later failures if we
go down code branches that do not support constant time, but check for

- Use extended regular expressions for better readability (less quoting)

Tolerate DTLS alerts with an incorrect version number

In the case of a protocol version alert being sent by a peer the record
version number may not be what we are expecting. In DTLS records with an
unexpected version number are silently discarded. This probably isn't
appropriate for alerts, so we tolerate a mismatch in the minor version
number.

This resolves an issue reported on openssl-users where an OpenSSL server
chose DTLS1.0 but the client was DTLS1.2 only and sent a protocol_version
alert with a 1.2 record number. This was silently ignored by the server.

Clarify error for unrecognized arguments.

Many of the sub-commands under apps/ accept cipher or digest arguments like
"-sha256". These are implemented using a catchall flag that runs the result
through opt_md() or opt_cipher(). That means any unrecognized flag, including
typos, gets sent to those two functions, producing confusing error messages like
below:

    $ ./apps/openssl req -x590
    req: Unrecognized digest x590
    req: Use -help for summary.

This change switches these two functions to say "Unrecognized flag X" instead.
The new message deliberately leaves off the "-" from the flag name, because
there are some cases where opt_md() and opt_cipher() are passed a flag value
instead (for instance, openssl ca -md). I think the new message is generic
enough that it can serve both cases with improved clarity.

Separate general linking flags from extra libraries

So far, we've placed all extra library related flags together, ending
up in the make variable EX_LIBS.  This turns out to be problematic, as
for example, some compilers don't quite agree with something like
this:

    cc -o foo foo.o -L/whatever -lsomething

They prefer this:

    cc -L/whatever -o foo foo.o -lsomething

IBM's compiler on OS/390 is such a compiler that we know of, and we
have previously handled that as a previous case.

The answer here is to make a more general solution, where linking
options are divided in two parts, where one ends up in LDFLAGS and
the other in EX_LIBS (they corresponds to what is called LDFLAGS and
LDLIBS in the GNU world)
