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.

+ This option enables a simple self-test of the glob_match
+ function on startup. It is primarily useful for people
+ working on the code to ensure they haven't introduced any
+ regressions.

+ It only adds a little bit of code and slows kernel boot (or
+ module load) by a small amount, so you're welcome to play with
+ it, but you probably don't need it.
