[PATCH v16 2/4] tools/include: move xc_bitops.h to xen-tools/bitops.h

[dmkhn@xxxxxxxxx]

From: Denis Mukhin <dmukhin@xxxxxxxx> 

Move xc_bitops.h to common tools location to be shared between
the toolstack and unit test code.

Adjust the guard in xen-tools/bitops.h

Correct the #include directives and comments referring to the old
xc_bitops.h in the toolstack code.
