349807608f Remove /* foo.c */ comments 
This was done by the following
        find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
        print unless $. == 1 && m@/\* .*\.[ch] \*/@;
        close ARGV if eof; # Close file to reset $.

And then some hand-editing of other files.

62e3163b1b ECPublicKey_set_octet_string and ECPublicKey_get_octet_string 
behaviour was not quite consistent with the conventions
for d2i and i2d functions as far as handling of the 'out'
or 'in' pointer is concerned.

This patch changes this behaviour, and renames the functions to
o2i_ECPublicKey and i2o_ECPublicKey (not 'd2i' and 'i2d' because the
external encoding is just a raw object string without any DER icing).

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 :-)
