knock-on work than expected - they've been extracted into a patch
series that can be completed elsewhere, or in a different branch,
before merging back to HEAD.

Initial support for CMS.

Add zlib compression BIO.

Add AES key wrap implementation.

Generalize S/MIME MIME code to support CMS and/or PKCS7.

I thought it was about time I dusted this off. This stuff had been sitting on
my hard drive for *ages* (2003 in fact). Hasn't been tested well and may not
work properly.

Nothing uses it at present which is just as well.

Think of this as a traditional Christmas present which looks far more
impressive in the adverts and on the box, some of the bits are missing and
falls to bits if you play with it too much.

to bother creating a BIO around it.  So here's a few more functions to
make it possible to make the dump using a printing callback, and to
print to a FILE* (based on the callback variant), done in the same
style as the functions in crypto/err/err_prn.c.

we're using the printing functions correctly or not.

I used the corresponding attributes found in the header files of my
Linux installation.

let's make that a void *.  Also, BIO_socket_nbio() should send it an int
argument, not a long.

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

record-oriented fashion.  That means that every write() will write a
separate record, which will be read separately by the programs trying
to read from it.  This can be very confusing.

The solution is to put a BIO filter in the way that will buffer text
until a linefeed is reached, and then write everything a line at a
time, so every record written will be an actual line, not chunks of
lines and not (usually doesn't happen, but I've seen it once) several
lines in one record.  Voila, BIO_f_linebuffer() is born.

Since we're so close to release time, I'm making this VMS-only for
now, just to make sure no code is needlessly broken by this.  After
the release, this BIO method will be enabled on all other platforms as
well.

(it's similar to the shutdown(..., SHUT_WR) system call
for sockets).

Update docs.

Add docs for BIO_find_type() and friends.

Added function BIO_next() otherwise you can't
traverse a chain without accessing BIO internals.

found myself needing it a number of times, the latter for completeness.

'openssl asn1parse'.  As a side effect, the functions ASN1_parse_dump
and BIO_dump_indent are added.

Fixes for Win32 build.

This is mostly a work around for the old VC++ problem
that it treats func() as func(void).

Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.

The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.

Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)

After some messing around this seems to work but needs
a few more tests. Working out the syntax for sk_set_cmp_func()
(cast it to a function that itself returns a function pointer)
was painful :-(

Needs some testing to see what other compilers think of this
syntax.

Also needs similar stuff for ASN1_SET_OF etc etc.
