[Chicken-users] JAPI update and inline extension

[felix]

Hello!

- The JAPI library doesn't expose SRFI-4 (integer vectors are passed
 as normal Scheme vectors). This is a step towards unifying the JAPI
 interfaces of Chicken and the one done by Johannes Leveling for Bigloo.

- The `inline' extension compiles C on the fly (similar to the Perl and
 Python inline things). It's a bit simpler (no C parsing), but is quite 
easy
 to use:

 % csi
 >>> (require-for-syntax 'inline)
 >>> ((inline int () "return(42);"))     ; compiles and loads a .so
 42
 >>> ((inline int () "return(42);"))     ; reinvokes loaded code
 42
 >>> ,q
 % csi
 >>> (require-for-syntax 'inline)
 >>> ((inline int () "return(42);"))     ; loads .so from cache
 42


cheers,
felix
