When using Zephyr, we also want to use the proper wc_GenerateSeed
method. However, if one of the defines is set (e.g., NO_STM32_RNG), the
Zephyr option is ignored, although it would work. Hence, we have to
change the order in which these settings for the source of a random seed
are evaluated.

wolfssl_sce_unit_test.c:
sce_crypt_Sha_AesCbcGcm_multitest(): duplicate condition
ssl_asn1.c:
wolfSSL_i2t_ASN1_OBJECT(): done is not needed
MonthStr(): fix bounds check on i
woolfcrypt_test.c, test_main.c, wolfssl_tsip_unit_test.c, devices.c,
aes.c, des3.c:
Variable not used.
asn.c:
DecodeSubjKeyId(): sz is unsigned - check for less than zero does
nothing
kcapi_rsa.c:
KcapiRsa_Decrypt(): fix ret check by using else
KcapiRsa_Encrypt(): make same change for consistency
kcapi_hash.c:
KcapiHashFinal(): move ret into #ifdef where it is needed
stm32.c:
wc_Stm32_Hash_GetDigest(): i redeclared with different type - use ii
instead
bio.c, conf.c:
XFREE checks for NULL
Reduce scope of varialbes.
Condition same.
Tested with `./configure --disable-asm --enable-32bit --enable-asn=original --enable-cryptonly CFLAGS="-Wconversion -pedantic" && make`. Some progress with ASN template, but not complete.
Fix checking of negative with unsigned variables.
Check digestSz for 0 in wc_SSH_KDF() so that no possibility of dividing
by zero.
Change XMEMCPY to XMEMSET in renesas_sce_util.c.
Fix test.c to free prvTmp and pubTmp on read error.
Remove unused variables.
XFREE checks for NULL so don't check before call.
Move variable declarations to reduce scope.
--enable-entropy-memuse enables the software base entropy gatherer.
The entropy source uses difference in timing to read/write cache lines.
Random indeces into a buffer are updated with the high resolution timer
value which is fed into a hash to produce further random indeces.
The current time is added to the entropy samples at time of
conditioning.
When initializing the RNG and are using RDRAND, or one of the other
replacement random number generators that could fall back to the
Hash_DRBG if unavailable, set the status to DRBG_OK. This would fix a
problem if someone assumes the DRBG status is meaningful.
