Change the EVP_somecipher() and EVP_somedigest()
functions to return constant EVP_MD and EVP_CIPHER
pointers.

Update docs.

Use example group from Annex I of X9.62 in ectest.c.

and an ectest.c that actually tests something.

because an incompletely initialized ASN1_INTEGER was used.

use _emit instead

Incease the number of BIGNUMs in a BN_CTX.

Make EVP_Digest*() routines return a value.

TODO: update docs, and make soe other routines
which use EVP_Digest*() check return codes.

"make depend"

The filenames we are interested in for Makefile dependencies
are always relative.

Change mkerr.pl so that it puts the ERR_load_..._strings()
prototype in header files that it writes.

(It cannot possibly help to avoid duplicate 'name of file' strings
in object files because the preprocessor does not work at object file
level.)

including EC arithmetics derived from Lenka Fibikova's code (with some
additional optimizations).

(they can't do much useful, but they will have to set pointers
to NULL)

(This will be used for Lim/Lee precomputation data.)
