Enrico Weigelt, metux IT consult 7ea43bd5e9 dix: let change_modmap() return BadValue instead of -1
The function returns X result codes, but -1 isn't a valid value here.
Therefore all callers explicitly translate -1 to BadValue, so we can return
that directly instead of -1.

Make it type-safe and a bit more obvious what it really does,
also adding some inline documentation. Since it's just some
bit shifting magic, it's qualified for inlining.

The CLIENT_ID() macro isn't used by any external modules, so the
new function doesn't need to be in a public header.

Enrico Weigelt, metux IT consult 55544ff85f Xi: use calloc() instead of malloc()
Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.

The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.

The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.
