Jilles Tjoelker 0a62a9caa9 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.

# This file lists all the builtin commands. The first column is the name
# of a C routine.
# The -j flag specifies that this command is to be excluded from systems
# without job control.
# The -h flag specifies that this command is to be excluded from systems
# based on the NO_HISTORY compile-time symbol.
# The -s flag specifies that this is a POSIX 'special built-in' command.
# The rest of the line specifies the command name or names used to run the
# command. The entry for bltincmd, which is run when the user does not specify
# a command, must come first.
#
# NOTE: bltincmd must come first!
