Reduce code duplication and print better error message if an
unsupported cpu number was passed.

The current cpulist_parse() function ignores extra non-parsable characters at
the end of the to be parsed cpu list string. E.g. it would accept something
like "0bla" and just set bit 0 in the cpu set. Since such a string is invalid
implement stricter parsing that makes sure that everything of the string has
been succesfully parsed.

If cpulist_parse() gets passed a cpu list with a stride value of 0 it will be
stuck in an endless loop. E.g. the following cpu list will cause an endless
loop: "0-2:0". Fix this by causing a parse error if the stride value is 0.

The opening and closing braces for two following if statements within
cpulist_parse() are placed in an odd manner.
Just fix this to prevent broken code in the future.

The comments for cpumask_parse() and cpulist_parse() each describe
the wrong function. Just exchange the comments.

This is a preparation patch for chcpu. If a cpu should be added to
a cpu_set where the cpu doesn't fit into the cpu_set this got silently
ignored.
Since the cpu-list is user space provided it should be checked if cpus
are specified that are completely out of range of the system.
In order to do that add a parameter which specifies if cpulist_parse()
should fail if it parses a cpu-list with "impossible" cpus.
The current callers have been converted so they behave like before.

It does not make sense to have writable large arrays of "struct
option" on the stack.

The free() before exit() is not so important, but let's keep the
example code nice and consistent.

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

The glibc already supports dynamically allocated CPU sets. We don't
have to maintains our private non-compatible implementation.
