libsec: fix verifyDHparams() for version <= TLS1.1
for version <= TLS1.1, there is no sigalg field in the ServerKeyExchange
message and the signature digest algorithm is fixed to md5+sha1 and we
only support RSA signatures (TLS1.1 doesnt know about ECDSA).

kbdfs: read outer /dev/kbd file and use it just like /dev/kbdin
this allows running kbdfs under kbdfs :-)
going use this in new drawterm. drawterm provides the initial
/dev/kbd, but only sends rune up/down messages (keeps it simple).
the servers kbdfs reads that and exports itself the full
set of files, similar to what we do in vncs. this also
provides note processing.

ndb/dns: initialize unknown fids to point to the root qid
the dns file service can be restarted, which causes it to forget
all fid state. given the simple file system structure of the dns
service (just a single dns file), we can assume that rpcs
on a unknown fid refers to the root, so the mountpoint will stay
valid and /net/dns can be reopend avoiding the need for a remount
of the dns service after restart.

rc: terminate rc when exec fails, cleanup
The execexec() function should never return, as it irreversably changes
the filedescriptor table for the new program. This means rc's internal
filedesciptors for reading the script get implicitely closed and we cannot
continue the rc interpreter when Execute() fails. So Execute() now sets the
error status, and execexec() runs Xexit() in case Execute() returns.

factotum: fix memory leak for p9any key confirmation, fix key handling for role=client
when we look up role=speakfor key and askforkeys is set, the
findkey() can return RpcNeedkey, which causes us to skip the
query for a role=client key. Instead, we now check for the
return value != RpcOk (and != RpcConfirm which we want to
handle the same for both queries).
we have to free the attribute lists when returning RpcConfirm.

exportfs: fix endless loop for eof/error on second read in localread9pmsg()
the ini buffer was not reset when we got eof in the message

adding experimental rcpu service
this is a reimplementation of cpu and import utilities in rc using a tlsclient
and tlssrv as the encryption and authentication layers. there is only one new
service, which after authentication and encryption setup accepts an arbitrary
rc script over the network and executes it with the standard filedescriptors
redirected to the conversaion (this is *after* authentication and in the
context of the authorized user).
the new rcpu program has a few improvements over cpu(1):
- doesnt mangle program arguments
- the remote process will get the clients standard file descriptors, so error
and output are separated and you can consume the clients input from the
remote side :-)
- forwards error status of remote process
theres no backwards mode for rimport, but a new program called rexport
for the same purpose.
all these services use exportfs without the bolted on initial handshake,
so the hope is to clean up exportfs in the future and remove all the ugly
crap in there.

provide /n and /mnt early in bootrc to allow consistent use in /lib/namespace
theres a bootstrap problem:
when /bin/init is run, it processes /lib/namespace where we might want to
mount or bind resources to /n or /mnt. but mntgen was run later in
cpurc/termrc so these mounts would be ignored.
we already have mntgen in bootfs, so we can provide these mountpoints early.
i keep the termrc/cpurc mntgens where they are, but ignore the error
prints. this way old kernels will continue to work.

rio: fix wrong frame colors when moving non-current window
When a window is moved or reshaped, that implicitely tops
the window and makes it current. The conseqence of this
is that we always have to redraw the window as if it where
a current window in any case. This was handled for Reshaped
windows, but not when the window was just moved. We now
handle both cases the exact same way, getting rid of the
Moved wctl message.

pc/pc64: bring up ap's one after another, use idlehands() while waiting for thunderbirdsarego
when testing in qemu, launching each ap became slower and slower
because all the ap's where spinning in syncclock() waiting for
cpu0 to update its mach0->tscticks, which happens only much later
after all cpu's have been started up.
now we wait for each cpu to do its timer callibration and
manually update our tscticks while we wait and each cpu will
not spin but halt while waiting for active.thunderbirdsarego.
this reduces the system load and noise for timer callibration
and makes the mp startup linear with regard to the number of
cores.

fdisk: properly convert byte units K,M,G and T to cylinders/sectors
the shared command language assumed 512 byte sectors, which is
not the case for fdisk as it uses cylinders for the block unit.
so we introduce an extra argument in the Edit structure and
parseexpr() function so byte sizes are properly converted to
the block unit when the K,M,G and T postfixes are used.
