Previously, the RNG sets `initialized=1` after the first call to
RAND_poll(), although its criterion for being initialized actually
is whether condition `entropy >= ENTROPY_NEEDED` is true.
This commit now assigns `initialized=(entropy >= ENTROPY_NEEDED)`,
which has the effect that on the next call, RAND_poll() will be
called again, if it previously failed to obtain enough entropy.

At the bottom of https://tools.ietf.org/html/rfc5280#page-12 and
top of https://tools.ietf.org/html/rfc5280#page-13 (last paragraph
of above https://tools.ietf.org/html/rfc5280#section-3.3), we see:
This specification covers two classes of certificates: CA
certificates and end entity certificates. CA certificates may be
further divided into three classes: cross-certificates, self-issued
certificates, and self-signed certificates. Cross-certificates are
CA certificates in which the issuer and subject are different
entities. Cross-certificates describe a trust relationship between
the two CAs. Self-issued certificates are CA certificates in which
the issuer and subject are the same entity. Self-issued certificates
are generated to support changes in policy or operations. Self-
signed certificates are self-issued certificates where the digital
signature may be verified by the public key bound into the
certificate. Self-signed certificates are used to convey a public
key for use to begin certification paths. End entity certificates
are issued to subjects that are not authorized to issue certificates.
that the term "self-issued" is only applicable to CAs, not end-entity
certificates. In https://tools.ietf.org/html/rfc5280#section-4.2.1.9
the description of path length constraints says:
The pathLenConstraint field is meaningful only if the cA boolean is
asserted and the key usage extension, if present, asserts the
keyCertSign bit (Section 4.2.1.3). In this case, it gives the
maximum number of non-self-issued intermediate certificates that may
follow this certificate in a valid certification path. (Note: The
last certificate in the certification path is not an intermediate
certificate, and is not included in this limit. Usually, the last
certificate is an end entity certificate, but it can be a CA
certificate.)
This makes it clear that exclusion of self-issued certificates from
the path length count applies only to some *intermediate* CA
certificates. A leaf certificate whether it has identical issuer
and subject or whether it is a CA or not is never part of the
intermediate certificate count. The handling of all leaf certificates
must be the same, in the case of our code to post-increment the
path count by 1, so that we ultimately reach a non-self-issued
intermediate it will be the first one (not zeroth) in the chain
of intermediates.

It appears that, in FIPS mode, `ec_precompute_mont_data()` always failed
but the error was ignored until commit e3ab8cc from #6810.
The actual problem lies in the fact that access to the `mont_data` field
of an `EC_GROUP` struct should always be guarded by an
`EC_GROUP_VERSION(group)` check to avoid OOB accesses, because `group`
might come from the FIPS module, which does not define the `mont_data`
field inside the EC_GROUP structure.
This commit adds the required check before any access to
`group->mont_data` in `EC_GROUP_set_generator()`.

Fixes#7240
In FIPS mode, the default FIPS DRBG uses the drbg_get_entropy()
callback to reseed itself, which is provided by the wrapping
libcrypto library. This callback in turn uses ssleay_rand_bytes()
to generate random bytes.
Now ssleay_rand_bytes() calls RAND_poll() once on first call to
seed itself, but RAND_poll() is never called again (unless the
application calls RAND_poll() explicitely). This implies that
whenever the DRBG reseeds itself (which happens every 2^14
generate requests) this happens without obtaining fresh random
data from the operating system's entropy sources.
This patch forces a reseed from system entropy sources on every
call to drbg_get_entropy(). In contrary to the automatic reseeding
of the DRBG in master, this reseeding does not break applications
running in a chroot() environment (see c7504aeb640a), because the
SSLEAY PRNG does not maintain an error state. (It does not even
check the return value of RAND_poll() on its instantiation.)
In the worst case, if no random device is available for reseeding,
no fresh entropy will be added to the SSLEAY PRNG but it will happily
continue to generate random bytes as 'entropy' input for the DRBG's
reseeding, which is just as good (or bad) as before this patch.
To prevent ssleay_rand_bytes_from_system() (and hence RAND_poll())
from being called twice during instantiation, a separate
drbg_get_nonce() callback has been introduced, which is identical
with the previous implementation of drbg_get_entropy().
