This is proof that Hammer can be linked and used in a windows
program!

These are transliterations of the existing C files.
They're not particularly Pythonic or performant, but they're a start.

Example of usage

```
$ echo '  YW55IGNhcm5hbCBwbGVhcw==' | PYTHONPATH=../build/opt/src/bindings/python/ python base64.py
inputsize=27
input=  YW55IGNhcm5hbCBwbGVhcw==
((((89L, 87L, 53L, 53L), (73L, 71L, 78L, 104L), (99L, 109L, 53L, 104L), (98L, 67L, 66L, 119L), (98L, 71L, 86L, 104L)), (99L, 'w', '=', '=')),)
$ echo '  YW55IGNhcm5hbCBwbGVhcw==' | PYTHONPATH=../build/opt/src/bindings/python/ python base64_sem1.py
inputsize=27
input=  YW55IGNhcm5hbCBwbGVhcw==
(97L, 110L, 121L, 32L, 99L, 97L, 114L, 110L, 97L, 108L, 32L, 112L, 108L, 101L, 97L, 115L)
$ echo '  YW55IGNhcm5hbCBwbGVhcw==' | PYTHONPATH=../build/opt/src/bindings/python/ python base64_sem2.py
inputsize=27
input=  YW55IGNhcm5hbCBwbGVhcw==
(97L, 110L, 121L, 32L, 99L, 97L, 114L, 110L, 97L, 108L, 32L, 112L, 108L, 101L, 97L, 115L)
```

Now we can do things like:

# copy-paste from output
ring.<t,L,tie,Cn,M,Ln,I,D,J,Rn,A,K,F,G> = QQ[]
ID = ring.ideal(L - (1*Cn*t),tie - (1*Ln*t),Cn - (1*I + 1*J),M - (1*t^2),Ln - (1*D + 1*L + 1*M),I - (1*Rn*t),D - (1*Rn*t),J - (1*Ln*t),Rn - (1*F + 1*G + 1*K),A - (1*tie),K - (1*t^2),F - (1*Ln*t),G - (1*Cn*t))

# we are interested in tie in terms of t; so we want to remove anything not these two:
ID.elimination_ideal([L,Cn,M,Ln,I,D,J,Rn,A,K,F,G])

# output from this SageMath command is
# Ideal (t^3 + 2*t^2*tie + t*tie - tie) of Multivariate Polynomial Ring in t, L, tie, Cn, M, Ln, I, D, J, Rn, A, K, F, G over Rational Field
# which we can solve for tie to get tie = t^3/(1-t-2*t^2) just as expected

I don't think these actually affect correctness since there's no way for
0x40 or 0x60 to show up in a parse tree anyway, but they're confusing.

effects throughout, including use of inttypes.h/PRI[ud]64 because printf() is
still stuck in a long world, conversion of %lu to %zu for printing values of
type size_t, and changing/renaming the g_check_cmp* family of functions.
