-/* Bignum consistency macros
- * There is one "API" macro, bn_fix_top(), for stripping leading zeroes from
- * bignum data after direct manipulations on the data. There is also an
- * "internal" macro, bn_check_top(), for verifying that there are no leading
- * zeroes. Unfortunately, some auditing is required due to the fact that
- * bn_fix_top() has become an overabused duct-tape because bignum data is
- * occasionally passed around in an inconsistent state. So the following
- * changes have been made to sort this out;
- * - bn_fix_top()s implementation has been moved to bn_correct_top()
- * - if BN_DEBUG isn't defined, bn_fix_top() maps to bn_correct_top(), and
- * bn_check_top() is as before.
- * - if BN_DEBUG *is* defined;
- * - bn_check_top() tries to pollute unused words even if the bignum 'top' is
- * consistent. (ed: only if BN_DEBUG_RAND is defined)
- * - bn_fix_top() maps to bn_check_top() rather than "fixing" anything.
- * The idea is to have debug builds flag up inconsistent bignums when they
- * occur. If that occurs in a bn_fix_top(), we examine the code in question; if
- * the use of bn_fix_top() was appropriate (ie. it follows directly after code
- * that manipulates the bignum) it is converted to bn_correct_top(), and if it
- * was not appropriate, we convert it permanently to bn_check_top() and track
- * down the cause of the bug. Eventually, no internal code should be using the
- * bn_fix_top() macro. External applications and libraries should try this with
- * their own code too, both in terms of building against the openssl headers
- * with BN_DEBUG defined *and* linking with a version of OpenSSL built with it
- * defined. This not only improves external code, it provides more test
- * coverage for openssl's own code.
