Modified Files:
        src/sys/kern: subr_evcnt.c

Log Message:
avoid an error in the recent sys/evcnt.h change to drop the 0
array size from evcnt_sysctl:ev_strings that clang does not like.

the previous "struct xevcnt_sysctl" was well defined as the
evcnt_sysctl with array length of 0 could be placed as the
anywhere in other structures, but with [] it must remain last
and xevcnt_sysctl then places a char array afterwards.

avoid this entirely by removing struct xevcnt_sysctl, combining
the string array + struct evcnt_sysctl size manually for the
allocation, and moving all "ev_string" accesses to be via the
new [] array.
