Recently, OCSP_basic_verify() was changed to always return 0 on error,
when it would previously return 0 on error and < 0 on fatal error.
This restores the previous semantics back.

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.

Rebuild error source files: the new mkerr.pl functionality will now
pick up and translate static function names properly.

(Also improve util/ck_errf.pl script, and occasionally
fix source code formatting.)

Enhance OCSP_request_verify() so it finds the signers certificate
properly and supports several flags.

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.

Doesn't handle SSL URLs yet.

Fix ASN1_TIME_to_generlizedtime().

Add protoype for OCSP_response_create().

Add OCSP_request_sign() and OCSP_basic_sign()
private key and certificate checks and make
OCSP_NOCERTS consistent with PKCS7_NOCERTS

Various OCSP responder utility functions.

Delete obsolete OCSP functions.

Largely untested at present...

Initial OCSP certificate verify. Not complete,
it just supports a "trusted OCSP global root CA".

OCSP basic response verify. Very incomplete
but will verify the signatures on a response
and locate the signers certifcate.

Still needs to implement a proper OCSP certificate

Fix warning in RAND_egd().

Add set of OCSP client functions. All experimental

Add two OCSP nonce utility functions.

Fix typo in status code name.

Remove extensions argument from various functions

New function OCSP_cert_to_id() to convert a pair

New simple OCSP HTTP function. This is rather primitive
but just about adequate to send OCSP requests and
parse the response.

Fix typo in CRL distribution points extension.

Fix ASN1 code so it adds a final null to constructed

This is a little unusual because it can contain no

NCONF_get_number_e() is defined (_e for "error checking") and is
promoted strongly.  The old NCONF_get_number is kept around for
binary backward compatibility.

Actually, it's a feature that it goes looking at environment
variables.  It's just a pity that it's at the cost of the error
checking...  I'll see if I can come up with a better interface for
this.

the result.

I have retained the old behavior of the CONF_* functions, and have
added a more "object oriented" interface through NCONF_* functions
(New CONF, you see :-)), working the same way as, for example, the
BIO interface.  Really, the CONF_* are rewritten so they use the
NCONF_* functions internally.

In addition to that, I've split the old conf.c code into two files,
conf_def.c and conf_api.c.  conf_def.c contains the default config
object that reads a configuration file the standard OpenSSL way, as
well as configuration file with Win32 registry file syntax (I'm not
sure I got that one right).  conf_api.c provides an API to build other
configuration file readers around (can you see a configuraion file in
XML?  I can :-)).

Finally, I've changed the name conf_lcl.h to conf_def.h, since it's
made specifically for that "class" and none others.

still needed by the DEF generator...). I also ran the script with the -rewrite
