Florian Weimer 507f55c05f Linux: Use mmap instead of malloc in dirent/tst-getdents64 
malloc dirties the entire allocated memory region due to M_PERTURB
in the test harness.

Florian Weimer a620bd7935 Linux: Adjust gedents64 buffer size to int range [BZ #24740] 
The kernel interface uses type unsigned int, but there is an
internal conversion to int, so INT_MAX is the correct limit.
Part of the buffer will always be unused, but this is not a
problem.  Such huge buffers do not occur in practice anyway.

Florian Weimer 51ea67d548 Linux: Add getdents64 system call 
No 32-bit system call wrapper is added because the interface
is problematic because it cannot deal with 64-bit inode numbers
and 64-bit directory hashes.

A future commit will deprecate the undocumented getdirentries
and getdirentries64 functions.
