Modified Files:
        src/lib/libc/gen: posix_spawn.3 posix_spawn_file_actions_addopen.3
            posix_spawn_file_actions_init.3 posix_spawn_fileactions.c
        src/sys/compat/netbsd32: netbsd32_execve.c
        src/sys/kern: kern_exec.c

Log Message:
Limit the amount of kernel memory a posix_spawn syscall can use (for handling
the file action list) by limiting the maximum number of file actions to
twice the current file descriptor limit.
Fix a few bugs in the support functions and document the new limit.
