unify the keyboard and mouse readers into one using the hid
report parser for both. remove the keyboard protocol handling,
as it is now handled by hid parser and all we get is a sequence
of keycodes in Hiddev.k[] which we diff for up/down and translate
to pc scancodes.

in backwards mode, the roles of the aan filters need to be
reversed. add "-n address" option to import to override the
announce address for the aan server part (default tcp!*!0).

mischief!)
mischief got babble error with his mobile phone as we used to
read at max 64 bytes for the data response phase. his device
has 512 byte packet size.
thans to mischief for the patience.

ipifcunbind() could error out from ipifcremlifc() and Medium.unbind()
*after* decrementing ifc->conv->inuse! move the decrement after
calling these functions.
make ipifcremlifc() never raise error but return error string.
the only places where it could error is when it calls into
medium functions like Medium.remroute() and Medium.remmulti().
Ignore these errors as they could happen when the ethernet driver
crashed (think imported ethernet device or usb ethernet
in userspace), so we will be able to unbind.
add waserror() handlers as neccesary to deal with errors from
Medium.addmulti(), Medium.areg() and arpenter() to properly
unlock the data structures.

this allows setting the secstore server with secstore=tcp!example.com!secstore or secstore='$secstore' to read from ndb.

the allow command now takes an optional uid argument for the user
to be granted temporary god status on the fileserver for maintenance.
this was kenji okomotos idea, so thanks :)
remove wstatallow and writeallow flags. instead, we have global:
int allowed;
that contains the uid of the currently allowed user id or -1
if permission checking is globally disabled for the fileserver.
when zero, normal permission checking takes place.
added int isallowed(File*) function that returns non-zero when the
context is the console, or the allowed user. this is also used internally
by iaccess(), so all the extra code of in the callers of iaccess()
is gone now.
dont conflate allowed user with noauth flag and auto-allow on ream.
the installer already knows about noauth and allow flags so theres no
problem with bootstraping.

cleanup
when mountmux() completes a request for another process, enforce odering
of the loads and stores to the request prior to writing q->done = 1
so mntflushfree() sees q->done != 0 only when the request has actually
completed. otherwise, the q->done = 1 store could have been reordered
before the load from q->z, reading from already freed request and causing
spurious wakeups.
removing unused mntstats callback.
use nil for pointers instead of 0.

note how a in alarmed is a kernel address!
the first Ureg* argument is passed to the note handler in the
RARG (BX) register, which was not loaded when returning to
userspace from syscall() thru forkret(). fix by returning thru
noteret() from syscall().

remove impossible checks, rewrite as while loop.

interrupt notes go to the child process, not the filesystem
and filter process.

way emulating it

old iostats failed to work when builidng the kernel due to old bugs
that where already fixed in exportfs. instead of backporting the fixes,
reimplement iostats as a filter that sits between exportfs and the
process mount. from users perspective, theres no difference.
the result is much smaller and can handle everything that exportfs
can like /srv.

Xqdol() used to take quadratic time because of strcat(),
the code isnt really needed as list2str() aready does the
same thing in linear time without the strcat().
add estrdup() which uses emalloc() so allocation error are
catched.
move strdups() of name from callers into newvar().
avoid recursion of conclist(), and avoid copying of word
strings by providing Newword() function which doesnt copy
the word string.
