Sys::Hostname - Try every conceivable way to get hostname

David Sundstrom <sunds@asictest.sc.ti.com> Texas Instruments XS code added by Greg Bacon <gbacon@cs.uah.edu> perl v5.40.1 2025-07-27 Sys::Hostname(3perl)

Attempts several methods of getting the system hostname and then caches the result. It tries the first available of the C library's gethostname(), `$Config{aphostname}`, uname(2), syscall(SYS_gethostname), `hostname`, `uname -n`, and the file /com/host. If all that fails it "croak"s. All NULs, returns, and newlines are removed from the result.
