This patch changes Feather-Trace to allocate memory for the minor
devices dynamically, which addresses a long-standing FIXME. It also
provides clean module exit and error conditions for Feather-Trace.

This patch implements support for Feather-Trace devices to use the sysfs
file system and, consequently, udev support.
This allows us to allocate major/minor numbers for Feather-Trace
devices dynamically, which is desirable because our old static
allocations tend to create conflicts on modern distributions and/or
when there are many cores.

quantity on x86_64. Always cast it to int to avoid the warning.

Large sched_trace buffers cause boot problems on the ARM box. Allow
the user to specify smaller buffers.

Setting FT_TASK_TRACE_MAJOR, LOG_MAJOR, FT_TRACE_MAJOR to 0
allows to have them automatically assigned by the kernel
