7be5a1fbf4 In lib/libthread_db/arch/i386/libpthread_md.c, clang gives two incorrect 
warnings about alignment, so turn -Wcast-align off for now.

ef6f47c4ae Change lwp to int64_t as thr_pread_long() always uses a 64-bit value 
in order to account for LP64 targets when cross-debugging on ILP32,
allowing r224683 to compile on ILP32.
Note that thr_p{read,write}_{long,ptr}() still incorrectly use the size
of the respective types on the host rather than that on the target when
accessing the target address space which still needs to be fixed. This
means that r224683 alone may not be sufficient to solve the problem it's
intended to fix when cross-debugging.

e31fe879a8 The tid member of struct pthread actually is long so read it as such. 
Accessing it as an int causes failure on big-endian LP64, i.e. mips64be,
powerpc64 and sparc64.

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.

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.
