Update EC ASN.1 and print routines to use EC_KEY_oct2priv and
EC_KEY_priv2oct.
Reviewed-by: NViktor Dukhovni <viktor@openssl.org>

New functions EC_KEY_oct2priv and EC_KEY_priv2oct. These are private key
equivalents of EC_POINT_oct2point and EC_POINT_point2oct which convert
between the private key octet format and EC_KEY.

New functions to return internal pointer for order and cofactor. This

Add CRYPTO_EX_DATA add EndC_KEY_[gs]et_method, From Roumen Petrov.
Had to add various exdata calls to init/copy/free the exdata.
Had to remove const from some EC functions because exdata isn't
const-correct. :(
Also remove EC_EXTRA_DATA and use a union to hold the possible
pre-computed values and an enum to tell which value is in the
union. (Rich Salz)

Add EC_KEY_METHOD. This is part of the EC revision and will make EC behave
more like other algorithms. Specifically:

EC_KEY_METHOD is part of EC_KEY.
It is part of ENGINE.
Default or key specific implementations can be provided to redirect some
or all operations.

Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.

Likewise, move crypto/foo/footest.c to test/footest.c, instead of
symlinking it there.

Many applications require named curve parameter encoding instead of explicit
parameter encoding (including the TLS library in OpenSSL itself). Set this
encoding by default instead of requiring an explicit call to set it.
