Description
Safe accessors (and length) should be implemented as C_inline functions in chicken.h, since the accessors in srfi-4.scm are rather slow.

Since quite a lot of checking has to be done, it appears to be ok to keep the functions as normal Scheme code instead of implementing inline routines on the C level. srfi-4.scm has been heavily cleaned up an tuned and should be efficient enough (or at least more efficient) now.

tickets.
Reminders:
1) Provide safe rewrite-rules the expand into inline calls like:
1) Use macros to generate
XXXvector-length/-ref/-set!instead of higher order functions, and use safe inline routines (like the one above)
