rework sysconf table to treat zero entries as invalid
based on patch by Timo Teräs. previously, the value zero was used as a
literal zero, meaning that all invalid sysconf "names", which should
result in sysconf returning -1, had to be explicitly listed. (in
addition, it was not possible for sysconf to set errno to EINVAL, as
there was no distinction between -1 as an error and -1 as a valid
result.)
now, the value 0 is used for invalid/undefined slots in the table and
a new switch table entry is used for returning literal zeros.
in addition, an off-by-one error in checking against the table size is
fixed.
