967b888d8c Reduce iterations in concatenate! 
This commit should reduce the amount of iterations in concatenate to N
where N is the sum of the lengths of the input lists.

The previous implementation iterated from the beginning in each
concatenation because of `last-pair`.

This implementation is significantly faster in this extreme case:

(concatenate! `(,(iota 50000) ,@(map list (iota 500))))

>> Previous implementation:
real	0m0.671s
user	0m0.658s
sys	0m0.013s

>> This implementation:
real	0m0.175s
user	0m0.174s
sys	0m0.001s

The tests is done using `time`, which is not reliable at all, but using
`(trace last-pair)` shows accurately what happens with the iterations.

1ecf7f9c8a SRFI-144: accept zero arguments for flmax/flmin 
SRFI-144 requires that (flmin) returns +inf.0 and that
(flmax) returns -inf.0, so these procedures can't really
be aliases to the Chibi implementation of R7RS max and min.

6cafda8916 Decouple syntax-case from the Chibi core. 
This restores third-party (ab)users of the Chibi macro system such
as in https://gist.github.com/baguette/2632464, while allowing us
to break those uses in more interesting ways.

It also keeps the core slightly smaller (both in C and Scheme)
and speeds up the macro expansion process.
