Fix tests for the new library/executable naming scheme Also add new tests for the platform-specific and compiler-specific versioning scheme. A rough summary is: 1. A bug in how run_tests.py:validate_install checked for files has been fixed. Earlier it wasn't checking the install directory properly. 2. Shared libraries are no longer installed in common tests, and the library name/path testing is now done in platform-specific tests. 3. Executables are now always called something?exe in the installed_files.txt file, and the suffix automatically corrected depending on the platform. 4. If a test installs a file called 'no-installed-files', the installed files for that test are not validated. This is required to implement compiler-specific tests for library names/paths such as MSVC vs MinGW 5. The platform-specific file renaming in run_tests.py has been mostly removed since it is broken for shared libraries and isn't needed for static libraries. 6. run_tests.py now reports all missing and extra files. The logic for finding these has been reworked. 9 years ago			`usr/bin/prog?exe`
Rework installation logic so we can go outside the install prefix. 10 years ago			`usr/diiba/daaba/file.dat`
Cache the scripts used for postconf and install phases Cache the absolute dir that the script is searched in and the name of the script. These are the only two things that change. Update the test to test for both #1235 and the case when a script of the same name is in a different directory (which also covers the subproject case).
