Add GPT and RAIDframe support to bootloaders
Classic BIOS (/boot) and EFI bootloaders can now name devices
using the NAME=gpt_label syntax, or using raid partitions. Here
are examples:
boot NAME=root:/netbsd
boot raid0e:/netbsd
Correct the memset(3)'s third argument in i386 biosdisk.c
The size of allocation is the size of the structure biosdisk, not the size
of a pointer.
Document new GPT and RAIDframe capacity of bootstrap code
While there, also document EFI setup and some bugs
Typo fixes, 'file system'; new sentence, new line; expand IA-32.
Bump date for previous.
Make sure devices names are copied including last byte
Fix from M. Levinson.
