lib: add lib/glob.c This is a helper function from drivers/ata/libata_core.c, where it is used to blacklist particular device models. It's being moved to lib/ so other drivers may use it for the same purpose. This implementation in non-recursive, so is safe for the kernel stack.

lib: remove back_str initialization Clang static analysis reports this false positive glob.c:48:32: warning: Assigned value is garbage or undefined char const *back_pat = NULL, *back_str = back_str; ^~~~~~~~ ~~~~~~~~ back_str is set after back_pat and it's use is protected by the !back_pat check. It is not necessary to initialize back_str, so remove the initialization.

lib: glob.c: added null check for character class Add null check for character class. Previously, an inverted character class could result in a nul byte being matched and lead to the function reading past the end of the inputted string.

Revert "lib: Revert use of fallthrough pseudo-keyword in lib/" This reverts commit 6a9dc5fd6170 ("lib: Revert use of fallthrough pseudo-keyword in lib/") Now that we can build arch/powerpc/boot/ free of -Wimplicit-fallthrough, re-enable these fixes for lib/.
