This patch makes the taskset command independent of the system's maximum
number of cpus (CONFIG_NR_CPUS). The maximum for CONFIG_NR_CPUS is a
moving target.
With this patch the size of the systems's cpumask_t is gotten from
sched_getaffinity(2).
This patch uses variable length bitmasks borrowed from Paul Jackson's
variable size bitmask routines (hence I kept his copyright notice).
This replaces the use of the glibc CPU_SETSIZE, CPU_SET, CPU_ZERO and
CPU_ISSET macros which depend on a hardcoded size for cpu_set_t.
(also fixes one little nit: the -V option is "-v" in the built-in help, so
changed the built-in help)
