ec38ddc765 Clean-up GAS targets: get rid of "cpp" stuff and replace it with "purified" 
COFF and a.out targets [similar to ELF targets]. You might notice some
rudementary support for shared mingw builds under cygwin. It works (it
produces cryptoeay32.dll and ssleay32.dll with everything exported by
name), but it's primarily for testing/debugging purposes, at least for
now...

- Remove unused and unuseful debug cruft.

9088d5f24f As Nils put it; 
Yet another question: some time ago you changed BN_set_word.
    Why didn't you change BN_get_word as well?

Quite. I'm also removing the older commented-out implementations to improve
readability. This complex stuff seems to date from a time when the types
didn't match up well.

cf9056cfda BN_div_word() was breaking when called from BN_bn2dec() (actually, this is 
the only function that uses it) because it would trip up an assertion in
bn_div_words() when first invoked. This also adds BN_div_word() testing to
bntest.
