bcd9e0dd20 - Add two new system calls: preadv() and pwritev() which are like readv() 
and writev() except that they take an additional offset argument and do
  not change the current file position.  In SAT speak:
  preadv:readv::pread:read and pwritev:writev::pwrite:write.
- Try to reduce code duplication some by merging most of the old
  kern_foov() and dofilefoo() functions into new dofilefoo() functions
  that are called by kern_foov() and kern_pfoov().  The non-v functions
  now all generate a simple uio on the stack from the passed in arguments
  and then call kern_foov().  For example, read() now just builds a uio and
  calls kern_readv() and pwrite() just builds a uio and calls kern_pwritev().

bbe7bbdfee Eliminate the original method of requesting notification of aio_read(2) and 
aio_write(2) completion through kevent(2).  This method does not work on
64-bit architectures.  It was deprecated in FreeBSD 4.4.  See revisions
1.87 and 1.70.2.7.

Change aio_physwakeup() to call psignal(9) directly rather than indirectly
through a timeout(9).  Discussed with: bde

Correct a bug introduced in revision 1.65 that could result in premature
delivery of a signal if an lio_listio(2) consisted of a mixture of
direct/raw and queued I/O operations.  Observed by: tegge

ccfddc1cce Clarify the behavior of ptrace(2) a little bit: the tracing process 
must first attach to the traced process.  If the tracing process
exits without detaching, the traced process will be killed rather
than continued.  For the duration of the tracing session, the traced
process is reparented to the tracing process (with resulting expected
behaviors).  It is permissible to trace more than one other process
at a time.  When using waitpid() to monitor the behavior of the traced
process, signals are intercepted: they may optionally then be
forwarded using ptrace().  Signals are generated normally by and for
the process, but also by the tracing facility (SIGTRAP).
