Protect safe_mem_lib.h from old systems without wchar.h

== Problem
When the library was installed to the system and a user attempted
to compile against the library the compile would fail.

== Reason
The problem was due to some types not being defined in the public API
of the library.

== Solution
Changed the public API, header files, of the library so that a few
of the files are now auto-generated based on information discovered
by the configure script. The header files that are now auto-generated
are 'safe_lib_errno.h' and 'safe_types.h'.

What changed from original:
- Documented how to setup the source tree for building in the README
- removed all makefiles that were obsoleted by autotools
- removed runtime_environment.c as it was not referenced by any other
  code within the library
- had to edit safe_types.h due to a compile error, may
  need to make this more portable later
- library can now be compiled as a shared and static object, all symbols
  are exported which is something I hope to change
- tests are now run when 'make check' is run
- converted the build to be silent like a Linux source compile
- requires/has been tested with autoconf(v2.65), automake(v1.11),
  and libtool(v2.2.6)

Still a lot of things need to be done:
- finish writing the definitions for the rest of the test programs
- convert the configure options to actually be configurable
  instead of someone having to go in and change code
- fix up the header files so that they can be parsed to
  generate an export symbols files
- fix up the header ...
