[Xen-devel] [PATCH 1 of 2 V4] libxc, libxenstore: make the headers C++-friendlier

[Razvan Cojocaru <rzvncj@xxxxxxxxx>]

Made the xenctrl.h and xenstore.h easier to use with C++:
added 'extern "C"' statements, moved the definition of
enum xc_error_code above it's typedef.

Signed-off-by: Razvan Cojocaru <rzvncj@xxxxxxxxx>
