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.

84b08eee4b Reorganise ECC code for inclusion in FIPS module.
Move compression, point2oct and oct2point functions into separate files.

Add a flags field to EC_METHOD.

Add a flag EC_FLAGS_DEFAULT_OCT to use the default compession and oct
functions (all existing methods do this). This removes dependencies from
EC_METHOD while keeping original functionality.

b6358c89a1 Convert openssl code not to assume the deprecated form of BN_zero().
Remove certain redundant BN_zero() initialisations, because BN_CTX_get(),
BN_init(), [etc] already initialise to zero.

Correct error checking in bn_sqr.c, and be less wishy-wash about how/why
the result's 'top' value is set (note also, 'max' is always > 0 at this
point).

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 :-)
