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.

Reminders:

1) Provide safe rewrite-rules the expand into inline calls like:

 (##core#inline "C_i_u8vector_length" X 'u8vector) ; need to pass sym for checking structure tag

1) Use macros to generate `XXXvector-length/-ref/-set!` instead of higher order functions, and use safe inline routines (like the one above)

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.
