001ab3abad Use double dashes so makedepend doesn't misunderstand the flags we
give it.
For 0.9.7 and up, that means util/domd needs to remove those double
dashes from the argument list when gcc is used to find the
dependencies.

cb78486d97 This commits changes to various parts of libcrypto required by the recent
ENGINE surgery. DH, DSA, RAND, and RSA now use *both* "method" and ENGINE
pointers to manage their hooking with ENGINE. Previously their use of
"method" pointers was replaced by use of ENGINE references. See
crypto/engine/README for details.

Also, remove the ENGINE iterations from evp_test - even when the
cipher/digest code is committed in, this functionality would require a
different set of API calls.

79aa04ef27 Make the necessary changes to work with the recent "ex_data" overhaul.
See the commit log message for that for more information.

NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.

5cbc2e8bc1 Give DH, DSA, and RSA functions to "up" their reference counts. Otherwise,
dependant code has to directly increment the "references" value of each
such structure using the corresponding lock. Apart from code duplication,
this provided no "REF_CHECK/REF_PRINT" checking and violated
encapsulation.

b7727ee616 The indexes returned by ***_get_ex_new_index() functions are used when
setting stack (actually, array) values in ex_data. So only increment the
global counters if the underlying CRYPTO_get_ex_new_index() call succeeds.
This change doesn't make "ex_data" right (see the comment at the head of
ex_data.c to know why), but at least makes the source code marginally less
frustrating.

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.

35ed8cb8b6 Integrate my implementation of a countermeasure against
Bleichenbacher's DSA attack.  With this implementation, the expected
number of iterations never exceeds 2.

New semantics for BN_rand_range():
BN_rand_range(r, min, range) now generates r such that
     min <= r < min+range.
(Previously, BN_rand_range(r, min, max) generated r such that
     min <= r < max.
It is more convenient to have the range; also the previous
prototype was misleading because max was larger than
the actual maximum.)

ef33b97050 Using checks of the existence of HEADER_{foo}_H in other header files
was a really bad idea.  For example, the following:

	#include <x509.h>
	#include <bio.h>
	#include <asn1.h>

would make sure that things like ASN1_UTCTIME_print() wasn't defined
unless you moved the inclusion of bio.h to above the inclusion of
x509.h.  The reason is that x509.h includes asn1.h, and the
declaration of ASN1_UTCTIME_print() depended on the definition of
HEADER_BIO_H.  That's what I call an obscure bug.

Instead, this change makes sure that whatever header files are needed
for the correct process of one header file are included automagically,
and that the definitions of, for example, BIO-related things are
dependent on the absence of the NO_{foo} macros.  This is also
consistent with the way parts of OpenSSL can be excluded at will.

26a3a48d65 There have been a number of complaints from a number of sources that names
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.

7e70181723 It was a very bad idea to use #include "../e_os.h" -- when this occurs
in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers.  So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes.  Argh.

bb8f3c5879 General source tree makefile cleanups: Made `making xxx in yyy...' display
consistent in the source tree and replaced `/bin/rm' by `rm'.  Additonally
cleaned up the `make links' target: Remove unnecessary semicolons, subsequent
redundant removes, inline point.sh into mklink.sh to speed processing and no
longer clutter the display with confusing stuff. Instead only the actually
done links are displayed.

6c8abdd744 New err_code.pl script to retain old error codes. This should allow the use
of 'make errors' without causing huge re-organisations of files when a new
code is added.

9cb0969f65 Fix version stuff:
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).
