kill: Note that this is used both as a normal program and a shell builtin.

Make sys_signame upper case.

This matches the constants from with 'SIG' removed, which POSIX requires kill and trap to accept and 'kill -l' to write. 'kill -l', 'trap', 'trap -l' output is now upper case. In Turkish locales, signal names with an upper case 'I' are now accepted, while signal names with a lower case 'i' are no longer accepted, and the output of 'killall -l' now contains proper capital 'I' without dot instead of a dotted capital 'I'.

sh: Add kill builtin.

This allows specifying a %job (which is equivalent to the corresponding process group). Additionally, it improves reliability of kill from sh in high-load situations and ensures "kill" finds the correct utility regardless of PATH, as required by POSIX (unless the undocumented %builtin mechanism is used). Side effect: fatal errors (any error other than kill(2) failure) now return exit status 2 instead of 1. (This is consistent with other sh builtins, but not in NetBSD.) Code size increases about 1K on i386. Obtained from: NetBSD

kill: Stop processing if a syntactically invalid pid is encountered.

So a command like kill _HUP 1 now fails without sending SIGTERM to init. The behaviour when kill(2) fails remains unchanged: processing continues. This matches other implementations and POSIX and is useful for killing multiple processes at once when some of them may already be gone. PR: bin/40282

Do not restrict the allowed signals that can be specified by number

to the list of signals that has symbolic name. It was impossible to send rt signals with kill(1) due to the check. MFC after: 1 week
