ld.so: Add --list-tunables to print tunable values Pass --list-tunables to ld.so to print tunables with min and max values. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

glibc.malloc.arena_max: 0x0 (min: 0x1, max: 0x[f]+)
glibc.malloc.arena_test: 0x0 (min: 0x1, max: 0x[f]+)
glibc.malloc.check: 0 (min: 0, max: 3)
tunables: Disallow negative values for some tunables The glibc.malloc.mmap_max tunable as well as al of the INT_32 tunables don't have use for negative values, so pin the hardcoded limits in the non-negative range of INT. There's no real benefit in any of those use cases for the extended range of unsigned, so I have avoided added a new type to keep things simple.
