pc: get rid of fixed 8MB memory map (now dynamically between 4 to 16 MB depending on kernel size)
...
we now do mapping of KZERO to ROUND(end, 4*MB) where
end needs not to be above 16MB. this allows for bigger
kernels.

e820: handle duplicate and overlapping e820 entries, handle overflows
...
new algorithm:
sort entries by top address first. then for each entry we use:
base = max(base, last)
so we'll never map the same addresses twice.

add unified sigsearch() function to look for bios data structures
...
replace the various functions that searched for bios data structures by
a single sigsearch() one in pc/memory.c that will probe the various bios
data areas.
also, a new checksum() function was added that is to be used to validate
the structures found.
