Michal Privoznik 7c9a2d88cd virutil: Move string related functions to virstring.c
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

* specify a relative path in <emulator/> element, which, however, is not
* allowed by RelaxNG schema for domain XML. To work around it we add an
* extra '/' at the beginning of relative emulator path so that it looks
* like, e.g., "/./qemu.sh" or "/../emulator/qemu.sh" instead of
* "./qemu.sh" or "../emulator/qemu.sh" respectively. The following code
* detects such paths, strips the extra '/' and makes the path absolute.
