(cherry picked from commit 0239283d)

With the introduction of -pkeyopt, the number of bits may change
without |newkey| being updated.  Unfortunately, there is no API to
retrieve the information from a EVP_PKEY_CTX either, so chances are
that we report incorrect information.  For the moment, it's better not
to try to report the number of bits at all.

This commit destroys the free list pointers which would otherwise be
present in the returned memory blocks.  This in turn helps prevent
information leakage from the secure memory area.

Note: CRYPTO_secure_malloc is not guaranteed to return zeroed memory:
before the secure memory system is initialised or if it isn't implemented.

Apparently after internal/numbers.h defines INTx_MIN/MAX
stdint gets included and it defines those differently:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE\stdint.h(48):
 warning C4005: 'INT8_MIN': macro redefinition

Avoid that by changing the sequence in which the include files
appear in crypto/bio/b_print.c.

Originally fopen(3) was called from bio/bss_file.c, which performed the
aliasing. Then fopen(3) was moved to o_fopen.c, while "magic" definition
was left behind. It's still useful on 32-bit platforms, so pull it to
o_fopen.c.

Since 0.9.7, all i2d_ functions were documented to allocate an output
buffer if the user didn't provide one, under these conditions (from
the 1.0.2 documentation):

    For OpenSSL 0.9.7 and later if B<*out> is B<NULL> memory will be
    allocated for a buffer and the encoded data written to it. In this
    case B<*out> is not incremented and it points to the start of the
    data just written.

i2d_ASN1_OBJECT was found not to do this, and would crash if a NULL
output buffer was provided.
