Check that sprint, strcpy don't overflow.
Avoid some strlen operations when the previous sprintf return value can be used.
Also fix the undefined behaviour `*(long *)x = y` when x isn't a long or character pointer.
ISO/IEC 9899:1999 6.5/7 for the details.

Original text:
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

Fix lots of bugs that util/ck_errf.pl can detect automatically.
Various others of these are still left to fix; that's why
"make update" will complain loudly when run now.

This allows intermediate CAs to be created more easily.
PKCS12_create() now checks private key matches certificate.
Fix typo in x509 app.
Update docs.
New function ASN1_STRING_to_UTF8() converts any ASN1_STRING
type to UTF8.
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
This change includes all the name changes needed throughout all C files.
Add a bunch of functions to simplify the creation of X509_NAME structures.
Change the X509_NAME_entry_add stuff in req/ca so it no longer uses
X509_NAME_entry_count(): passing -1 has the same effect.
