[PATCH v2 1/4] util: Remove confusing static keyword use

'__n' is declared as static const which is confusing since it
would imply that __n is only initialized once.  This works out in the
end since the macro used in a separate anonymous block, but some compilers
(i.e. clang) will generate a symbol table entry for '__n'.  This is not
needed since the expression is always constant.

Declare '__n' as a const size_t instead since that is the type produced
by the sizeof() operation used by L_ARRAY_SIZE.

While here, also declare '__i' as size_t to match '__n'.
