[libvirt] [PATCH v2] Introduce APIs for splitting/joining strings

[Eric Blake]

> This introduces a few new APIs for dealing with strings.
> One to split a char * into a char **, another to join a
> char ** into a char *, and finally one to free a char **
> 
> There is a simple test suite to validate the edge cases
> too. No more need to use the horrible strtok_r() API,
> or hand-written code for splitting strings.
