New cofiguration for Unixwre and SCO,with slightly better granularity.  Contributed by Tim Rice <tim@multitalents.net>

ignores it anyway in command substitution, but Ultrix reportedly
aborted the test when bctest returned 1.

It now looks along $PATH for a working bc and returns the absolute
path to one that does work.

Add default values for display by the 'ca' utility
to openssl.cnf

Update docs.

seems like some Unixen (SCO) have opinions about too many -L.

Overhaul the display of certificate details in
the 'ca' utility. This can now be extensively
customised in the configuration file and handles
multibyte strings and extensions properly.

This is required when extensions copying from
certificate requests is supported: the user
must be able to view the extensions before
allowing a certificate to be issued.

It does not appear to be faster than the current Montgomery code
except for very small moduli (somewhere between 192 and 224 bits
in a 64-bit Sun environment, and even less than 192 bits
on 32 bit systems).

Document the -certopt option to the x509 utility.

Add no_issuer option.

Fix X509_print_ex() so it prints out newlines when
certain fields are omitted.

OPENSSL_SYSNAME_ULTRASPARC, so we'd better check for that one

which indicate its purpose more clearly.

The latter does nothing for now, but its existence means
that applications can request precomputation when appropriate.
