Don't wait for dry at the end of a handshake

For DTLS/SCTP we were waiting for a dry event during the call to
tls_finish_handshake(). This function just tidies up various internal
things, and after it completes the handshake is over. I can find no good
reason for waiting for a dry event here, and nothing in RFC6083 suggests
to me that we should need to. More importantly though it seems to be
wrong. It is perfectly possible for a peer to send app data/alerts/new
handshake while we are still cleaning up our handshake. If this happens
then we will never get the dry event and so we cannot continue.

Check for alerts while waiting for a dry event

At a couple of points in a DTLS/SCTP handshake we need to wait for a dry
event before continuing. However if an alert has been sent by the peer

This commit changes things so that we attempt to read a message if we
are waiting for a dry event but haven't got one yet. This should never
succeed, but any alerts will be processed.

INSTALL: Add a note about backward compatibility and "make variables"

Configure: maintain compability with pre-"make variables" Configure

There were a few environment variables that we supported in earlier
Configure versions which got transfered to the %user table.  This
change makes sure that we still support them, by simply pre-populating
the corresponding %user entries with those environment values.

Configure: Don't fail if there were "make variables" set in env

The original intent was that if someone had a "make variable" set in
any kind of way, be it as an environment variable or as an argument to
Configure, we wouldn't allow compiler or linker flags as arguments as
well.  That made both of these configurations equivalently impossible:

    ./Configure target CFLAGS=-foo -lextra

     CFLAGS=-foo ./Configure target -lextra

While this makes things look nice and consistent, real world use makes
this hard, as many projects where OpenSSL is a component also set
these variables for other components that use GNU autotools.

Therefore, we need to adapt our Configure accordingly.  By
consequence, the two Configure lines above will not be equivalent any
more:

    ./Configure target CFLAGS=-foo -lextra

This command line will still fail, because the "make variable" was
given as a command line argument.  This cannot be a mistake and is
therefore not allowed.

     CFLAGS=-foo ./Configure target -lextra

This command line will work, but because there is a linker flag as
a command line argument, the environment (i.e. CFLAGS) is ignored.
That isn't quite consistent with the previous command, but is the old
Configure behavior, before the support for "make variables" was added,
and is therefore the backward compatible behavior.

util/postprocess-makedepend.pl: For VC, don't include system headers

All dependencies that VC gives us are absolute paths, so we need to

by comparing the start of each dependency with the absolute versions

Streamline dependency generation

It seems that only gcc -MMD produces dependency files that are "sane"
for our needs.  For all other methods, some post processing is needed:

- 'makedepend' (Unix) insists that object files are located in the
  same spot as the source file.
- 'cl /Zs /showIncludes' (Visual C) has "Note: including file: " where
  we'd like to see the object.
- 'CC/DECC' (VMS) insists that the object file is located in the
  current directory, i.e. it strips away all directory information.

So far, we've managed this (except for the VMS case) with individual
uncommented perl command lines directly in the build file template.
We're now collecting these diverse hacks into one perl script that
takes an argument to tell what kind of input to expect and that
massages whatever it gets on STDIN and outputs the result on STDOUT.

Report a readable error on a duplicate cert in ca app

Commit 87e8feca (16 years ago!) introduced a bug where if we are
attempting to insert a cert with a duplicate subject name, and
duplicate subject names are not allowed (which is the default),
then we get an unhelpful error message back (error number 2). Prior
to that commit we got a helpful error message which displayed details
of the conflicting entry in the database.

That commit was itself attempting to fix a bug with the noemailDN option
where we were setting the subject field in the database too early
(before extensions had made any amendments to it).

This PR moves the check for a conflicting Subject name until after all
changes to the Subject have been made by extensions etc.

This also, co-incidentally fixes the ca crashing bug described in issue
5109.
