memset(3) has been in standard C since C89. It is also in
POSIX.1-2001, in SVr4, and in 4.3BSD (see memset(3) and memset(3p)).
We can assume that this function is always available.

sleep 2s before running newxidmap - it seems we were sometimes
racing, causing newxidmap to fail.
Make sure to remove /tmp/test-xidmap, for some reason they
were sometimes still there, causing test to fail.
Fix some irregular tabbing.

PARAMETERS:
According to the C2x charter, I reordered the parameters 'size'
and 'buf' from previously existing date_to_str() definitions.
C2x charter:
> 15. Application Programming Interfaces (APIs) should be
> self-documenting when possible. In particular, the order of
> parameters in function declarations should be arranged such that
> the size of an array appears before the array. The purpose is to
> allow Variable-Length Array (VLA) notation to be used. This not
> only makes the code's purpose clearer to human readers, but also
> makes static analysis easier. Any new APIs added to the Standard
> should take this into consideration.
I used 'long' for the date parameter, as some uses of the function
need to pass a negative value meaning "never".
FUNCTION BODY:
I didn't check '#ifdef HAVE_STRFTIME', which old definitions did,
since strftime(3) is guaranteed by the C89 standard, and all of
the conversion specifiers that we use are also specified by that
standard, so we don't need any extensions at all.

The build was failing with duplicate symbol errors with -fno-common.
This is the default in GCC 10 and later, and explicitly enabled in some
distributions to catch problems like this. There were two causes:
- Prog and shadow_logfd were defined in a header file that was included
in multiple other files. Fix this by defining them once in
shadowlog.c, and having extern declarations in the header.
- Most of the tools (except id/nologin) also define a Prog variable,
which is not intended to alias the one in the library. Fix
this by renaming Prog in the library to shadow_progname, which also
matches the new accessor functions for it.
We were overriding this when --enable-shared was passed. We can actually
just dump the conditional logic as libtool will do the right thing for
us here anyway.
Without this patch, libsubid is installed as .0.

The SIGCHLD handler could have been ignored by parent process.
Make sure that we have default handling activated.

That special case is already handled by the called function: strtoday()
so we can simplify the calling code.
