* Add 'warning density' computation to the warnhist script, along with several cleanups to it. Add "--enable-show-all-warnings" configure (and CMake) option to disable compiler diagnostic suppression (and therefore show all the otherwise suppressed compiler diagnostics), disabled by default. Clean up a buncn of misc. warnings. Signed-off-by: Quincey Koziol <qkoziol@amazon.com>
