Added safe mode option B_SAFEMODE_4_GB_MEMORY_LIMIT (plus a boot loader menu
item) and kernel settings option "4gb_memory_limit". Enabling either one
causes the memory beyond 4 GB to be ignored.

* Added option for enabling serial debug output.
* Moved device_manager/settings.cpp to debug/safemode_settings.cpp.
* Removed the somewhat hacky concatenation of kernel settings and safemode
settings in the boot loader. Instead, get_safemode_option() will now fall
back to the kernel settings, if it couldn't spot a setting in the safemode
settings. This allows for more control, and also makes enabling serial
debug output actually work (ie. overriding the kernel settings via safemode
options).
* Adjusted debug_init_post_vm(), and smp_init_other_cpus() to use
get_safemode_boolean().
* Therefore, I added safemode_settings.cpp to the boot loader as well.

- introduced an "argumetns" field in stage2_args to hold command line args from chaining loader,
- added some multiboot support code:
- dump some of the passed info,
- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

* Update the size of the safemode settings "file" when concatenating it with
the kernel settings. Settings that were checked in the kernel (like on-screen
debug output) didn't work anymore, because when handing the settings over to
the kernel it would have copied only the old size part of the safemode file.
* Add a newline when the kernel and safemode settings are combined. Otherwise
the first safemode and last kernel setting would get lost if the kernel
settings file didn't end with a newline.

When the boot loader goes to load its settings files, it will now also prepend the "kernel" settings file to the safe mode settings if it exists. This allows settings from kernel/drivers/kernel to be respected early in the boot process as well, which allows us to do things like disable_smp permanently instead of having to pick from the safe mode menu every single boot. Review welcome.
