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.

affected source code and Makefiles.

The header files that got moved are:

830b8877ba Takanori Yanagisawa has shown how to correctly use pre-computed values. 
So in a sense this commit reverts few latest ones fixing bugs in original
code and improving it, most notably adding 64-bit support [though not in
BN_nist_mod_224 yet].

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).

a8aa764d3c Minimise the amount of code dependent on BN_DEBUG_RAND. In particular, 
redefine bn_clear_top2max() to be a NOP in the non-debugging case, and
remove some unnecessary usages in bn_nist.c.

27b2b78f90 Even though C specification explicitly says that constant type "stretches" 
automatically to accomodate the value, some compilers fail to do so. Most
notably 0x0123456789ABCDEF should come out as long long in 32-bit context,
but HP compiler truncates it to 32-bit value. Which in turn breaks GF(2^m)
arithmetics in hpux-parisc2-cc build. Therefore this fix...

0ef85c7f45 This is a revert of my previous commit to "improve" the declaration of 
constant BIGNUMs. It turns out that this trips up different but equally
useful compiler warnings to -Wcast-qual, and so wasn't worth the ugliness
it created. (Thanks to Ulf for the forehead-slap.)

d870740cd7 Put the first stage of my bignum debugging adventures into CVS. This code 
is itself experimental, and in addition may cause execution to break on
existing openssl "bugs" that previously were harmless or at least
invisible.

c465e7941e This is the least unacceptable way I've found for declaring the bignum data 
and structures as constant without having to cast away const at any point.
There is still plenty of other code that makes gcc's "-Wcast-qual" unhappy,
but crypto/bn/ is now ok. Purists are welcome to suggest alternatives.

31166ec8f3 Some provisional bignum debugging has begun to detect inconsistent BIGNUM 
structures being passed in to or out of API functions, and this corrects a
couple of cases found so far.

Also, lop off a couple of bytes of white-space.
