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.

Many wiki pages have become outdated and spam-ridden, we will import
these to trunk and begin maintaining them in ruby-trunk. This will
also allow new contributors to easily contribute patches to update
these pages, where previously a redmine account with wiki access was
required. Another bonus is having a contributors file to show thanks
to all of the people who have submitted a patch to Ruby.
