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.
