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.

Linux: Add the tgkill function
...
The tgkill function is sometimes used in crash handlers.
<bits/signal_ext.h> follows the same approach as <bits/unistd_ext.h>
(which was added for the gettid system call wrapper).

misc: Add twalk_r function
...
The twalk function is very difficult to use in a multi-threaded
program because there is no way to pass external state to the
iterator function.

Linux: Add gettid system call wrapper [BZ #6399 ]
