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/glob.c: add CONFIG_GLOB_SELFTEST This was useful during development, and is retained for future regression testing. GCC appears to have no way to place string literals in a particular section; adding __initconst to a char pointer leaves the string itself in the default string section, where it will not be thrown away after module load. Thus all string constants are kept in explicitly declared and named arrays. Sorry this makes printk a bit harder to read. At least the tests are more compact.
