as was done earlier in libssl. Thanks inoguchi@ for noticing
libssl had more reacharounds into this.

Split out BN_div and BN_mod into ct and nonct versions for Internal use.2017-01-21T10:38:29+00:00beck2017-01-21T10:38:29+00:00urn:sha1:55a172a1ed5b0cd8f7de3628fcc2e56df6716d59

BN_CTX_get() can fail - consistently check its return value.2015-02-09T15:49:22+00:00jsing2015-02-09T15:49:22+00:00urn:sha1:15dc63f9715f4f10924a705d6a4cc564afe2129e
There are currently cases where the return from each call is checked,
the return from only the last call is checked and cases where it is not
checked at all (including code in bn, ec and engine).
Checking the last return value is valid as once the function fails it will
continue to return NULL. However, in order to be consistent check each
call with the same idiom. This makes it easy to verify.
Note there are still a handful of cases that do not follow the idiom -
these will be handled separately.

Only import cryptlib.h in the four source files that actually need it.2014-07-11T08:44:49+00:00jsing2014-07-11T08:44:49+00:00urn:sha1:74e2c009c83ad374bd6acdcfc376a384e25ab007
Remove the openssl public includes from cryptlib.h and add a small number
of includes into the source files that actually need them. While here,
also sort/group/tidy the includes.

an OPENSSL_NO_* define. This avoids relying on something else pulling it
in for us, plus it fixes several cases where the #ifndef OPENSSL_NO_XYZ is
never going to do anything, since OPENSSL_NO_XYZ will never defined, due
to the fact that opensslconf.h has not been included.
This also includes some miscellaneous sorting/tidying of headers.

fields (i.e. the flags field) before using it. This is currently harmless,
but might not be if we end up invoking other BN functions checking for
constant-time processing requirement in the future.

The intent of this change is to only keep support for two kind of architectures:
- those with 32-bit int and long, and 64-bit long long, where
``long * long -> long long'' multiplication routines are available.
- those with 64-bit int and long, and no 128-bit long long type.
This gets rid of the SIXTY_FOUR_BIT_LONG, SIXTY_FOUR_BIT (not the same!),
THIRTY_TWO_BIT, SIXTEEN_BIT and EIGHT_BIT defines.
After this change, the types and defines are as follows:
arch: 64bit 32bit rationale
BN_LLONG undefined defined defined if l * l -> ll
BN_ULLONG undefined u long long result of BN_LONG * BN_LONG
BN_ULONG u long u int native register size
BN_LONG long int the same, signed
BN_BITS 128 64 size of 2*BN_ULONG in bits
BN_BYTES 8 4 size of 2*BN_ULONG in bytes
BN_BITS2 64 32 BN_BITS / 2
Tested on various 32-bit and 64-bit OpenBSD systems of various endianness.
