aa4ce7315f Fix various incorrect error function codes. 
("perl util/ck_errf.pl */*.c */*/*.c" still reports many more.)

35b73a1f20 Rename implementations of method functions so that they match 
the new method names where _GF... suffixes have been removed.

Revert changes to ..._{get/set}_Jprojective_coordinates_...:
The current implementation for ECC over binary fields does not use
projective coordinates, and if it did, it would not use Jacobian
projective coordinates; so it's OK to use the ..._GFp prefix for all
this.

Add author attributions to some files so that it doesn't look
as if Sun wrote all of this :-)

458c29175e move ECC ASN1 that is not specific to ECDSA into crypto/ec/, 
and make some appropriate changes to the EC library.

b6db386ffd Change internals of the EC library so that the functions 
EC_GROUP_{set_generator,get_generator,get_order,get_cofactor} are
implemented directly in crypto/ec/ec_lib.c and not dispatched to
methods.

Also fix EC_GROUP_copy to copy the NID.

af28dd6c75 Fix bugs and typos. 
Add some WTLS curves.
New function EC_GROUP_check() (this will probably
be implemented differently soon).

f1f25544e0 ..._init functions are method-specific too 
(they can't do much useful, but they will have to set pointers
to NULL)
