cd906041ea Add support for demangling C++ symbols. This requires linking libproc with
libc++rt/libsupc++.

19a75aff51 Make sure we visit both symbol sections even if one of them doesn't
exist. This makes it possible to dtrace some C++ programs like devd.

a8375da0d3 fix a serious bug in libproc's proc_attach
proc_attach always frees any struct proc_handle data
that it allocates, but that is supposed to be done
only in error conditions.

fe0c8f8973 Revert SHLIB_MAJOR to 2.
As discussed with kan@, since DTrace is the only consumer of libproc
right now, there's no need for a major shlib bump.

8eb20f364f New version of libproc. Changes are:
* breakpoint setup support
* register query
* symbol to address mapping and vice-versa
* more misc utility functions based on their Solaris counterpart

Also, I've written some test cases.

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.

3ca3047aee Bump the version of all non-symbol-versioned shared libraries in
preparation for 8.0-RELEASE.  Add the previous version of those
libraries to ObsoleteFiles.inc and bump __FreeBSD_Version.

2c633af461 Add a process library with some stubs that the DTrace client needs.
These will be fleshed out as part of the DTrace userland tracing
development.

For now, the kernel tracing part of DTrace requires minimal functionality
for this library.

The API for this library is deliberately different from the libproc in
OpenSolaris due to licensing restrictions.
