ramfs: replace with new lib9p based implementation
old ramfs had a limit on the number of files it could serve
and file size was limited to maximum allocaiton size.
the new implementation uses multiple memory chunks to back file data
in a private compactable memory pool to overcome these limits.
files can be sparse. file metadata is maintained by 9pfile data
structures of lib9p.

libdraw: fix zero stringwidth() bug
stringwidth() and string() sometimes failed spuriously due
to the wrong assumption that cachechars() will only fail
when a different subfont is needed. in fact, cachechars()
can fail for other reasons like when it resizes the fontcache
(or fails todo so).
theres also the case when loadchar() is unable to translate
a character and returns 0. this case needs to be differentiated
from such temporary conditions like fontcache resize or subfont
load to stop the retry loop in string() and stringwidth().
now cachechars() returns -1 to indicate that it cannot
proceed and we test this in string() and stringwidth()
to skip over untranslatable characters to make progress
instead of retrying.

pc64: fix segattach
the comment about Physseg.size being in pages is wrong,
change type to uintptr and correct the comment.
change the length parameter of segattach() and isoverlap()
to uintptr as well. segments can grow over 4GB in pc64 now
and globalsegattach() in devsegment calculates len argument
of isoverlap() by s->top - s->bot. note that the syscall
still takes 32bit ulong argument for the length!
check for integer overflow in segattach(), make sure segment
goes not beyond USTKTOP.
change PTEMAPMEM constant to uvlong as it is used to calculate
SEGMAXSIZE.

kernel: getting rid of duppage() (thanks charles)
simplifying paging code by getting rid of duppage(). instead,
fixfault() now always makes a copy of the shared/cached page
and leaves the cache alone. newpage() uncaches pages as
neccesary.
thanks charles forsyth for the suggestion.

libsec: improve thumbprint code
1) handle errors when loading thumbprint file.
initThumbprints() now returns nil and sets errstr
on error. a syntax error in a thumbprint file
should be reported instead of silently ignored!
(have to check users)
2) fix memory leak in initThumbprints(); we have to use
freeThumbprints() instead of free to release crltab.
3) use the actual head entries for thumbprint
storage in the thumbprints array. most thumbprint
files are rather sparse.
4) remove private emalloc() function. we shouldnt
just exit the calling process on allocation error,
instead handle error properly. this is a library!
