[PATCH v1] tools: convert bitfields to unsigned type

[Olaf Hering]

clang complains about the signed type:

implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 
to -1 [-Wsingle-bit-bitfield-constant-conversion]

The potential ABI change in libxenvchan is covered by the Xen version based 
SONAME.

The xenalyze change follows the existing pattern in that file.
