daaf575910 Build lib/ with WARNS=6 by default. 
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

03fad2ad5f Allow psaddr_t to be widened by using thr_pread_{int,long,ptr}, 
where critical. Some places still use ps_pread/ps_pwrite directly,
but only need changed when byte-order comes into the picture.
Also, change th_p in td_event_msg_t from a pointer type to
psaddr_t, so that events also work when psaddr_t is widened.

8d4e4b790a Add thr_pread_{int,long,ptr} and thr_pwrite_{int,long,ptr} to 
help abstract the sizes and endianness of the primary types of
the target.  These currently use the native characteristics.

00fb440c1a Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. 
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).

Change the default thread library to libthr.

There most likely still needs to be a version bump for at least the
thread libraries.  If necessary, this will happen later.
