* Mark all symbols not needed by Python as hidden

   The ELF standard allows you to mark symbols as hidden.  These
   symbols are global since they might be needed by other object
   files, however once the object files are linked into a Dynamic
   Shared Object (DSO) the hidden symbols are no longer visable.  The
   equivalent of this on XCOFF would have to be found too.

* Improve finding the terminal on Linux

   A scheme like aix_process.c uses should be used, but it should be
   improved slightly so that it will check the device id of the
   finally found device file.  And this code should probably be shared
   between all POSIX systems.

* Consider using PSI_STATUS_NA instead of ifdeffing around

   All the #ifdef blocks around descriptors/attributes and their
   respective getter functions is just going to spiral out of
   control.  Maybe all attributes should just be always available but
   raise an AttrNotApplicableError when accessed?

* Create a libpsi.a static library

   All utility functions should go into libpsi.a to simplify getting
   the correct dependencies in setup.py, this is arleady turning into
   an unmaintainable hell.  The setup.py script should then use
   distutils.ccompiler.has_function() and friends to produce a
   config.h for libpsi to know what to build.  This library can be
   built using the build_clib command from distutils.

   This will also mean that individual modules will be smaller since
   only the used symbols will exist in the sofiles, intead of all of
   them.

* Simplify module sources

   Code that is shared between archs should end up in libpsi.a.  And
   each arch must have it's <arch>_<thing>.c file, even if it is just
   calling the shared function an no more.

* Introduce procfs_read_struct()?

   For SunOS and AIX /proc files it could be possible, and safer and
   faster, not to dynamically allocate the memory but rather read into
   a statically allocated space.  You'd use it like:

     struct psinfo psinfo;

     if (procfs_read_struct(&psinfo, sizeof(struct psinfo), pid, "psinfo") < 0)
         return -1;

* Consider renaming the arch module

   The arch module really describes the whole system, not just the
   architecture.  Therefore the name is a bit misleading.  However
   calling it `sys' would clash with the stdlib sys module and
   `system' seems a bit long.

   How about `plat' or `platform'?  Note that `platform' is an stdlib
   module, so that might be a bad idea.

* Improve InsufficientPrivs error message

   It would be good if psi_checkattr() could also say what process the
   error message is for instead of just the attribute.

* Consider having ArchLinux24 and ArchLinux26 sub-types

   In the unittests I find myself having to say `if isinstance(arch,
   ArchLinux) and arch.release[:3] == "2.6"' often.  Maybe it would be
   easier if we could say `if isinstance(arch, ArchLinux26)'?
