malloc and realloc could return NULL when no memory is available.
The code doesn't handle errors, so use xmalloc/xrealloc instead.
While at it, sync alloclen's type with len's type, so both are ssize_t.
pwdx doesn't actually use any of the libprocps functions but
it is linked because it is the default. This specific LDADD
removes that unrequired linking.
pwdx rather mysteriously fails with "invalid process id" when run in a
nonexistent locale (e.g. "LC_ALL=foo pwdx $$"). This is because it
fails to obey the documented calling sequence for strtol - that is, set
errno to 0 before the call - and thus the errno from the setlocale
failure bleeds over into its check for whether strtol failed.

For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.
The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.
On some architectures/gcc's, the pwdx tool doesn't compile right
because of bad type of a variable. Afterwards pwdx can't be
persuaded to work. Use int as the type, like the other tools
(like pgrep) do.

If stream status is not checked at the end of execution below problem
would not report error, or non-zero exit code. The uptime is just an
example same was true with all commands of the project.
$ uptime >&- ; echo $?
uptime: write error: Bad file descriptor
1
$ uptime >/dev/full ; echo $?
uptime: write error: No space left on device

err and warn are BSD format but they are not recommended by library
developers. However their consiseness is useful!
The solution is to use some macros that create xerr etc which then
just map to the error() function. The next problem is error() uses
program_invocation_name so we set this to program_invovation_short_name
This is a global set but seems to be the convention (or at least errors
are on the short name only) used everywhere else.
Includes also magic number removal (return value 1 to EXIT_FAILURE),
and proper null assignment to end of string.

Add the following three functions to most of the commands.
setlocale (LC_ALL, "");
bindtextdomain(PACKAGE, LOCALEDIR);
textdomain(PACKAGE);
