dpkg moved to away from dynamically allocating the hashtables in commit
c87339d584 (dpkg: trivial code shrinkage, and redo G trick correctly) almost
ten years ago, but the cleanup code was never adjusted to match.
Glibc loudly complains about this:
*** Error in `dpkg': free(): invalid pointer: 0x0000007fac3478c0 ***

setpriv from util-linux has an option to dump the current state
regarding privilege settings via '--dump'. It prints out information on
the real and effective user and group IDs, supplementary groups, the
no-new-privs flag, the capability sets as well as secure bits.
This patch is the start of supporting this mode. To make introduction of
the '--dump' easier to reason about, its introduction has been split
into multiple patches. This particular one introduces the ability to
print out user and group information of the current process.

The current option parsing logic of setpriv only supports the case where
we want to execute a sub-program and have at most one argument. Refactor
handling of options to solve these shortcomings to make it easy to
support 'setpriv --dump', which does not accept any additional
arguments, as well as the case where additional options are passed to
setpriv. This is done by handling 'argc' ourselves, throwing an error
when no program is specified, as well as introducing an enum for the
different option bitmasks.

By default, the 'getopt32' call will continue parsing the command line
even after hitting a non-option string. But in setpriv, this should be
avoided, as all parameters following the initial non-option argument are
in fact arguments to the binary that is to be executed by setpriv.
Otherwise, calling e.g. 'busybox setpriv ls -l' would result in an error
due to the unknown parameter "-l".
Fix the issue by passing "+" as the first character in the options
string. This will cause 'getopt32' to stop processing after hitting the
first non-option.

Currently, BZCAT (and BUNZIP2) selects FEATURE_BZIP2_DECOMPRESS,
thus, "#if ENABLE_FEATURE_BZIP2_DECOMPRESS" around bunzip2_main()
is sufficient. But let's robustify it.

Before this change, BB_EXTRA_VERSION of "" resulted in:
"BusyBox v1.28.0.git () multi-call binary"
message, after the fix it is:
"BusyBox v1.28.0.git multi-call binary"
While at it, eliminate BB_BT and BANNER single-use macros.

Add a minimal 'setpriv' implementation supporting the NO_NEW_PRIVS bit.
Typical usage:
$ busybox setpriv sudo uname
Linux
$ busybox setpriv --nnp sudo uname
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with
the 'nosuid' option set or an NFS file system without root privileges?

Declaration of ls_longopts and initialization of applet_long_options
were incorrectly guarded with ENABLE_FEATURE_LS_COLOR; that yielded a
"ls: NO_OPT: \xff" error message when long options were selected and
color support was not. This patch ensures long options are
initialized separately from color support.
