missed any.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

Improve readability of bn_shift.c.

Add comment in bn_lib.c (why zero data between top and max?)

Change bntest.c output for BN_kronecker test

This caused a segmentation fault in calls to malloc, so I cleaned up
bn_lib.c a little so that it is easier to see what is going on.
The bug turned out to be an off-by-one error in BN_bin2bn.

Get the BN_mod_exp_mont bugfix (for handling negative inputs) correct
this time.

"make update"

  because otherwise BN_rand will fail unless DEVRANDOM works,
  which causes the programs to dump core because they
  don't check the return value of BN_rand (and if they
  did, we still couldn't test anything).

- add comment to some files that appear not to be used at all.
