bn_gf2m.c: optimized BN_GF2m_mod_inv delivers sometimes 2x of ECDSA sign.
...
Exact improvement coefficients vary from one benchmark and platform to
another, e.g. it performs 70%-33% better on ARM, hereafter less for
longer keys, and 100%-90% better on x86_64.

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).

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...
