Loading the config file after processing command line options can
cause problems, e.g. where an engine provides new ciphers/digests
these are not then recoginised on the command line. Move the
default config file loading to before the command line option
processing. Whilst we're doing this we might as well centralise
this instead of doing it individually for each application. Finally
if we do it before the OpenSSL_add_ssl_algorithms() call then
ciphersuites provided by an engine (e.g. GOST) can be available to
the apps.

The different apps had the liberty to decide whether they would open their
input and output files in binary mode or not, which could be confusing if
two different apps were handling the same type of file in different ways.
The solution is to centralise the decision of low level file organisation,
and that the apps would use a selection of formats to state the intent of
the file.

When generating a private key, try to make the output file be readable
only by the owner. Put it in CHANGES file since it might be noticeable.
Add "int private" flag to apps that write private keys, and check that it's
set whenever we do write a private key. Checked via assert so that this
bug (security-related) gets fixed. Thanks to Viktor for help in tracing
the code-paths where private keys are written.

Here are the "rules" for handling flags that depend on #ifdef:
- Do not ifdef the enum. Only ifdef the OPTIONS table. All ifdef'd
entries appear at the end; by convention "engine" is last. This
ensures that at run-time, the flag will never be recognized/allowed.
The next two bullets entries are for silencing compiler warnings:
- In the while/switch parsing statement, use #ifdef for the body to
disable it; leave the "case OPT_xxx:" and "break" statements outside
the ifdef/ifndef. See ciphers.c for example.
- If there are multiple options controlled by a single guard, OPT_FOO,
OPT_BAR, etc., put a an #ifdef around the set, and then do "#else"
and a series of case labels and a break. See OPENSSL_NO_AES in cms.c
for example.

The module loading feature got broken a while ago, so restore it, but
have it a bit more explicit this time around.

No point in proceeding if you're out of memory. So change
*all* OPENSSL_malloc calls in apps to use the new routine which
prints a message and exits.

This is merges the old "rsalz-monolith" branch over to master. The biggest
change is that option parsing switch from cascasding 'else if strcmp("-foo")'
to a utility routine and somethin akin to getopt. Also, an error in the
command line no longer prints the full summary; use -help (or --help :)
for that. There have been many other changes and code-cleanup, see
bullet list below.
Special thanks to Matt for the long and detailed code review.

I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.
exit() in whatever way works for the intended platform, and define
OPENSSL_EXIT() to have the old meaning (the name is of course because
it's only used in the openssl program)
CONF_modules_unload() now calls CONF_modules_finish()
automatically.
Default use of section openssl_conf moved to

Load config file in several openssl utilities.
Most utilities now load modules from the config file,
though in a few (such as version) this isn't done
because it couldn't be used for anything.
In the case of ca and req the config file used is
the same as the utility itself: that is the -config
command line option can be used to specify an
alternative file.
libdes (which is still used out there) or other des implementations,
the OpenSSL DES functions are renamed to begin with DES_ instead of
des_. Compatibility routines are provided and declared by including
openssl/des_old.h. Those declarations are the same as were in des.h
when the OpenSSL project started, which is exactly how libdes looked
at that time, and hopefully still looks today.
The compatibility functions will be removed in some future release, at
the latest in version 1.0.

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.
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.
