According to X6.90 null, object identifier, boolean, integer and enumerated
types can only have primitive encodings: return an error if any of
these are received with a constructed encoding.

Causes more problems than it fixes: even though error codes
are not part of the stable API, several users rely on the
specific error code, and the change breaks them. Conversely,
we don't have any concrete use-cases for constant-time behaviour here.
This reverts commit 1bb01b1b5f.

The 1**0 test will fail for FIPS capable builds because it uses the
old BIGNUM code in the 1.2 FIPS module which can't be fixed.

Reencode DigestInto in DER and check against the original: this
will reject any improperly encoded DigestInfo structures.
Note: this is a precautionary measure, there is no known attack
which can exploit this.
Thanks to Brian Smith for reporting this issue.

"inline" without static is not correct as the compiler may choose to ignore it
and will then either emit an external definition, or expect one.

Both volatile and "memory" are used because of some concern that the compiler
may still cache values across the asm block without it, and because this was
such a painful debugging session that I wanted to ensure that it's never
repeated.

This is actually ok for this function, but initialised to zero anyway if
PURIFY defined.
This does have the impact of masking any *real* unitialised data reads in bn though.

The object file bn_lib.o is excluded from FIPS builds which causes
a linker error for BN_consttime_swap. So move definition from bn_lib.c
to bn_gf2m.c
This change is *only* needed for OpenSSL 0.9.8 which uses the 1.2
FIPS module.
