3475bc9675 Add set methods.
Add set_group, set_public and set_private methods. An EC_KEY_METHOD can use
these to perform any appropriate operation when the key components are set,
such as caching data in some more convenient ENGINE specific format or
returning an error if the parameters are invalid or the operation is
not supported.

984d6c6052 Fix no-stdio build
Much related/similar work also done by
Ivan Nestlerode <ivan.nestlerode@sonos.com>

   +Replace FILE BIO's with dummy ops that fail.
   +Include <stdio.h> for sscanf() even with no-stdio (since the declaration
    is there). We rely on sscanf() to parse the OPENSSL_ia32cap environment
    variable, since it can be larger than a 'long'. And we don't rely on the
    availability of strtoull().
   +Remove OPENSSL_stderr(); not used.
   +Make OPENSSL_showfatal() do nothing (currently without stdio there's
    nothing we can do).
   +Remove file-based functionality from ssl/. The function
    prototypes were already gone, but not the functions themselves.
   +Remove unviable conf functionality via SYS_UEFI
   +Add fallback definition of BUFSIZ.
   +Remove functions taking FILE * from header files.
   +Add missing DECLARE_PEM_write_fp_const
   +Disable X509_LOOKUP_hash_dir(). X509_LOOKUP_file() was already compiled out,
    so remove its prototype.
   +Use OPENSSL_showfatal() in CRYPTO_destroy_dynlockid().
   +Eliminate SRP_VBASE_init() and supporting functions. Users will need to
    build the verifier manually instead.
   +Eliminate compiler warning for unused do_pk8pkey_fp().
   +Disable TEST_ENG_OPENSSL_PKEY.
   +Disable GOST engine as is uses [f]printf all over the place.
   +Eliminate compiler warning for unused send_fp_chars().

68886be7e2 EC_POINT_is_on_curve does not return a boolean
The function EC_POINT_is_on_curve does not return a boolean value.
It returns 1 if the point is on the curve, 0 if it is not, and -1
on error. Many usages within OpenSSL were incorrectly using this
function and therefore not correctly handling error conditions.

With thanks to the Open Crypto Audit Project for reporting this issue.

0f539dc1a2 Fix the update target and remove duplicate file updates
We had updates of certain header files in both Makefile.org and the
Makefile in the directory the header file lived in.  This is error
prone and also sometimes generates slightly different results (usually
just a comment that differs) depending on which way the update was
done.

This removes the file update targets from the top level Makefile, adds
an update: target in all Makefiles and has it depend on the depend: or
local_depend: targets, whichever is appropriate, so we don't get a
double run through the whole file tree.

b4faea50c3 Use safer sizeof variant in malloc
For a local variable:
        TYPE *p;
Allocations like this are "risky":
        p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption.  Instead do this:
        p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.
