* introduce new flag __UL_DEBUG_FL_NOADDR to suppress pointer address printing
* use __UL_DEBUG_FL_NOADDR when SUID
* move ul_debugobj() to debugobj.h, and require UL_DEBUG_CURRENT_MASK
to provide access to the current mask from ul_debugobj(). It's better
than modify all ul_debugobj() calls and use the global mask as
argument.
* remove never used UL_DEBUG_DEFINE_FLAG

We don't modify data it's pointing out and we should not modify it.
Also remove casting to void * as gcc will do it automatically (before
we had to cast it explicitly to avoid warning on discarding 'const'
qualifier).

Fix various typos in error messages, warnings, debug strings,
comments and names of static functions.

* use ul_debug_ prefix for all routines
* support <NAME>_DEBUG=all also for programs without debug mask names
(so we can avoid 0xffff mask in man pages)
* add function to print debug help

* use debug stuff from include/debug.h and make whereis(1) sensitive
to WHEREIS_DEBUG=0xffff mask
* fix problem with argv[] usage
# whereis -b -m -M /usr/share/man/man1 -B /usr/bin -f gcc
bin: /usr/local/bin
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz
the code ignores "-B" and /usr/bin is interpreted as search pattern,
expected result is:
# whereis -b -m -M /usr/share/man/man1 -B /usr/bin -f gcc
gcc: /usr/share/man/man1/gcc.1.gz /usr/bin/gcc

For example
$ LIBMOUNT_DEBUG=tab,cache findmnt
to debug only TAB and CACHE subsystem.
