Add IO#pread and IO#pwrite methods
These methods are useful for safe/concurrent file I/O in
multi-thread/process environments and also fairly standard
nowadays especially in systems supporting pthreads.
Based on patches by Avseyev <sergey.avseyev@gmail.com> at
[ruby-core:79290]. [Feature #4532]
* configure.in: check for pwrite(2). pread() is already used
internally for IO.copy_stream.
* io.c: implement wrappers for pread(2) and pwrite(2) and expose
them in IO.
