It can be useful to have a count to keep track of which argument number in the
list is being expanded.

The original ccan module does not include a macro to increment numbers. Add one
which will increment upto 32 which is enough for our usage.

The original implementation of non-empty will fail to compile if passed an
argument of the form 'CPPMAGIC_NONEMPTY((...))'. Add a check for parentheses and
return true if passed.

When cross compiling with uclibc under buildroot, we get the following
clash:
./ccan/endian/endian.h:84:24: error: redefinition of ‘__bswap_32’
static inline uint32_t bswap_32(uint32_t val)

Work around it by not using ccan's endian. There's only one call site, and we
can use a libc function instead.

The previous implementation of targeting was hardcoded, cumbersome
and difficult to reconfigure for different chip types. This moves to a
method of configuring targets using device-tree which is much easier
to maintain and allows methods to be added to support operations like
getmem on POWER9.

This includes better support for selecting targets, probing thread
status and a number of other minor bugfixes. Also adds an option to
print version numbers.
