SeaBIOS patches: advanced_bootmenu, multiple_floppies, writeprotected_usb

If you'd like to add the useful floppies to your coreboot (read about them at
http://dangerousprototypes.com/docs/Lenovo_G505S_hacking#Useful_floppies ), or
to use your USB numpad for choosing a SeaBIOS boot entry, or to boot from your
USB flash drive with a write protect switch enabled, - then this change is for
you! It contains three valuable patches together with a Makefile mod needed to
automatically apply these patches to a cloned SeaBIOS before its' compilation.

advanced_bootmenu: up to 35 entries (2 pages if >18), numpad support (console)

[PATCH v2] ramdisk: search for all available floppy images instead of one

[PATCHv2] Support booting USB drives with a write protect switch enabled

Patch descriptions are available at these links, and just in case here's a copy:

advanced_bootmenu: up to 35 entries (2 pages if >18), numpad support (console)

Add support for up to 35 boot menu entries (2 pages if >18). To solve the
">10" problem currently experienced by SeaBIOS users (there are no 11, 12, etc.
keys on a keyboard - so impossible to choose the last menu entries if you got
>10 entries because of multiple hard drives / secondary payloads / floppies)
- the boot menu has been extended to the letter keys. NOTE: TPM menu has been
moved from T to M letter: it is at the end of keyboard's 3rd row of letters and
"Trusted" is adjective while "Module" is a noun; alternatively could press '-'.

Also, add support for a numpad. Small USB numpad could be really convenient for
choosing the boot entries at coreboot boards used as (maybe headless) servers.
'/' char on numpad could be used to open the boot menu or to exit it. If there
are >10 boot menu entries - the numpad console interface will be enabled: press
one or two digit keys and then ENTER to confirm your choice, or remove a digit
by pressing the '.Del' key. Also you could call TPM with '-' key at any moment,
or boot with a single key press of your fullsize keyboard.

[PATCH v2] ramdisk: search for all available floppy images instead of one

All the floppy images available at CBFS will be found and listed in a boot menu,
instead of the first found. Could be highly valuable if you are participating in
a hobby OS development - would like to test multiple versions of your floppy at
the same coreboot image, to reduce the amount of re-flashes and accelerate the
development at bare metal - or simply you would like to access multiple floppies
as a coreboot user. For example: KolibriOS (nice assembly OS with GUI and apps),
FreeDOS, MichalOS, Snowdrop and memtest (coreboot's memtest version is buggy,
e.g. external USB keyboard isn't working at some laptops; floppy is much better)

[PATCHv2] Support booting USB drives with a write protect switch enabled

At least some USB drives with a write protect switch (e.g. Netac U335)
could report "MEDIUM NOT PRESENT" for a while if a write protect is enabled.
Instead of stopping the initialization attempts immediately, stop only after
getting this report for 3 times, to ensure the successful initialization
of such a "broken hardware".
