    Use BUF_strlcpy() instead of strcpy().
    Use BUF_strlcat() instead of strcat().
    Use BIO_snprintf() instead of sprintf().
    In some cases, keep better track of buffer lengths.

This was done by the following
        find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
        print unless $. == 1 && m@/\* .*\.[ch] \*/@;
        close ARGV if eof; # Close file to reset $.

And then some hand-editing of other files.

There are header files in crypto/ that are used by a number of crypto/
submodules.  Move those to crypto/include/internal and adapt the
affected source code and Makefiles.

The header files that got moved are:

crypto/cryptolib.h
crypto/md32_common.h

Add '-d' option for 'openssl version' (included in '-a').

Using different files caused problems because the dependencies
in the Makefiles produced by mk1mf.pl were for the standard case,
i.e. mentioned buildinf.h and not mk1mfinf.h.

use new file buildinf.h instead.

a pain to read when using 4-space tabs.

1. The already released version was 0.9.1c and not 0.9.1b

2. The next release should be 0.9.2 and not 0.9.1d, because
   first the changes are already too large, second we should avoid any more
   0.9.1x confusions and third, the Apache version semantics of
   VERSION.REVISION.PATCHLEVEL for the version string is reasonable (and here
   .2 is already just a patchlevel and not major change).
