-   If we have a maximum amount of characters permitted to be printed
    (for example "%.2s", which allows for a maximum of 2 chars), we
    minimize the number of characters from the string to printed to
    that size.
-   If there is space for padding and there is a maximum amount of
    characters to print (for example "%3.2s", which shall give at
    least a 1 space padding), the amount of characters to pad with
    gets added to the maximum so the minimum field size (3 in this
    example) gets filled out.

Someone wants to configure like this:

    PERL="/usr/bin/env perl" ./config

The end goal is to get that in the #! line of CA.pl and a few other
scripts.  That works well already, but in the Makefile, there were a
few lines looking like this:

    PERL=$(PERL) $(PERL) whatever.pl ...

Those need some quoting.

If using the msys console then msys attempts to "fix" command line
arguments to convert them from Unix style to Windows style. One of the
things it does is to look for arguments seperated by colons. This it
assumes is a list of file paths, so it replaces the colon with a semi-colon.
This was causing one of our tests to fail when calling the "req" command
line app. We were attempting to create a new DSA key and passing the
argument "dsa:../apps/dsa1024.pem". This is exactly what we intended but
Msys mangles it to "dsa;../apps/dsa1024.pem" and the command fails.
There doesn't seem to be a way to suppress Msys name mangling. Fortunately
we can work around this issue by generating the DSA key in a separate step
by calling "gendsa".

When closing down the socket in s_client Windows will close it immediately
even if there is data in the write buffer still waiting to be sent. This
was causing tests to fail in Msys/Mingw builds because TLSProxy doesn't see
the final CloseNotify.

I have experimented with various ways of doing this "properly" (e.g.
shutting down the socket before closing, setting SO_LINGER etc). I can't
seem to find the "magic" formula that will make Windows do this. Inserting
a short 50ms sleep seems to do the trick...but its not very "nice" so I've
inserted a TODO on this item. Perhaps someone else will have better luck
in figuring this out.

On Windows we were using the function _kbhit() to determine whether there
was input waiting in stdin for us to read. Actually all this does is work
out whether there is a keyboard press event waiting to be processed in the
input buffer. This only seems to work in a standard Windows console (not
Msys console) and also doesn't work if you redirect the input from some
other source (as we do in TLSProxy tests). This commit changes things to
work differently depending on whether we are on the Windows console or not.

In s_server we call BIO_sock_should_retry() to determine the state of the
socket and work out whether we should retry an operation on it or not.
However if you leave it too long to call this then other operations may
have occurred in the meantime which affect the result. Therefore we should
call it early and remember the result for when we need to use it. This fixes
a test problem on Windows.

Another issue with s_server on Windows is that some of output to stdout does
not get displayed immediately. Apparently more liberal use of BIO_flush is
required.
