1. "unsigned long long" isn't portable changed: to BN_ULLONG.
2. The LL prefix isn't allowed in VC++ but it isn't needed where it is used.
2. Avoid lots of compiler warnings about signed/unsigned mismatches.
3. Include new library directory pqueue in mk1mf build system.
4. Update symbols.

casts.

The function rsa_eay_mont_helper() has been removed because it is no longer
needed after this change.

- possibility of re-creation of the blinding parameters after a
  fixed number of uses (suggested by Bodo)
- calculatition of the rsa::e in case it's absent and p and q
  are present (see bug report #785)
- improve the performance when if one rsa structure is shared by
  more than a thread (see bug report #555)
- fix the problem described in bug report #827
- hide the definition ot the BN_BLINDING structure in bn_blind.c

("perl util/ck_errf.pl */*.c */*/*.c" still reports many more.)

  and BN_get_sign
- implement BN_set_negative as a function
- always use "#define BN_is_zero(a) ((a)->top == 0)"

util/libeay.num is important when building shared libraries, like
VMS.

Remove more bogus shadow warnings.
