sysctl: Replace do_proc_do{int,ulong,uint}vec with do_proc_vec
Make do_proc_vec static and parametrize by proc_vec_type enum which
defines the type being processed and selects which converter is "live".
Signed-ness and size are calculated based on proc_vec_type and
table->data is now walked as raw bytes and advanced by the element size;
the converter still performs the actual typed load/store. Pass converter
as a union to avoid a cast from void*. The public
proc_do{int,uint,ulong}vec_conv() prototypes and all converter
signatures in kernel/, fs/ and the header are therefore unchanged.
Remove do_proc_doulongvec_minmax. proc_doulongvec_minmax_conv uses a
converter callback passed by the caller instead of conversions based on
conv{mul,div}. Create uni and bi-direction converters for milliseconds
to jiffies in proc_doulongvec_ms_jiffies_minmax; which is the only user
of proc_doulongvec_minmax_conv.
Replace do_proc_douintvec{,_w,_r} functions with a call to do_proc_vec.
Disallow vectors for uint by returning -EINVAL when more than one
element is detected.
