We do whole-file reads in a few places, so unify to a fileio_read_file()
function.
To do this, we change the type of struct image->buf to a uint8_t *.
Where we do pointer manipulation on the image buffer, we need a
temporary void * variable.

Rather than setting ->sigbuf directly, add two functions to handle image
signature addition and removal:
image_add_signature(image, sig, sigsize);
image_remove_signature(image);
And warn when a signature is to be overwritten.

sbattach.c was generating a warning on compile:
../sbattach.c: In function ‘main’:
../sbattach.c:247:2: warning: implicit declaration of function ‘OpenSSL_add_all_digests’ [-Wimplicit-function-declaration]
OpenSSL_add_all_digests is defined in evp.h, so add the #include.

We're using OpenSSL, so need to grant binary distrbutors permission to
link with it.
Cleared with current contributors.

Check detached signatures to ensure that we're attaching a valid PKCS7
object. If no, show a warning message and skip the attach action.

Rather than requiring an explicit image_pecoff_parse, do it
unconditionally in image_load. We don't have any instances where we need
to do this separately.
