Experimental configuration code.

Incomplete, largely untested and subject to change/deletion.

errors can be tolerated, hide the error from 'make'.
This gives shorter output both if ranlib fails and if
it works.

and make all files the depend on it include it without prefixing it
with openssl/.

This means that all Makefiles will have $(TOP) as one of the include
directories.

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.

acceptable, since all that happens if it fails is a library with
an index, which makes linking slower, but still working correctly.

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.

file from a bio or fp. Added some more constification to the BN library.

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.

There were problems with putting e_os.h just into the top directory,
because the test programs are compiled within test/ in the "standard"
case in in their original directories in the makefile.one case;
and in the latter symlinks may not be available.

a -write option is needed to actually change anything. Second attempt at
getting rid of ERR, ERRC definitions: it might even work this time :-)

to error code script: it can now find untranslatable function codes (usually
because the function is static and not defined in a header: occasionally because
of a typo...) and unreferenced function and reason codes. To see this try:
perl util/mkerr.pl -recurse -debug
Also fixed some typos in crypto/pkcs12 that this found :-)
Also tidy up some error calls that had to be all on one line: the old error
script couldn't find codes unless the call was all on one line.

script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.

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.

code is added.
