Do not memleak "copy" in case of an error.
Do not use "sizeof(converted)" in snprintf(), since "converted" is a
"char *" (luckily, 8 >= sizeof(char *)). Also, remove "sizeof(char)"
which is guaranteed to be 1 by the C standard, and replace 8 with 12,
which is enough to hold any stringified int and does not consume more
memory (in both cases, the glibc malloc()ates a minimum-sized chunk).
sig.c had this odd logic where on non-Hurd systems it would undefine
SIGLOST. Fine for Hurd or amd64 Linux systems. Bad for a sparc which
has SIGLOST defined *and* is not Hurd.
Just check its defined, its much simpler.
Since the value of number_of_signals is known at compile time, we can
use a compile-time check instead. This also adds SIGLOST for the Hurd,
uses the correct signal counts for the Hurd and FreeBSD, and only gives
a compile-time warning when compiled on an unknown platform that it does
not know whether the number of signals is correct.
kill -l SIGHUP (or any other signal-name prefixed with "SIG")
would cause free() to be called with a bad pointer instead of
a pointer to what was allocated. Fix this and add test-case.
FreeBSD doesn't have SIGPWR so makes no sense in warning and assuming
its 29.

The function will convert a signal number string to a signal name, or
vice a verse. Return value is string, which is an function user is
expected to free after use.
