notes
------

This release adds aiju's games/timmy, a physics simulation game and a
bignum calculator for programmers called pc.

On the system side, we got a fast portable /dev/random now which is
based on the chacha stream cipher - carefully seeded once at boot time.
Cipher states for the rng and other kernel crypto services is now
kept in a separate memory pool which devproc will prohibit access to
and which automatically destroys the data on free.


kernel
------

acpi: _ADR and _BBN might be methods, so use amleval() to evaluate the value
aml: define amlintmask and set it according to DSDT revision (64bit / 32bit)
aml: implement ToInteger() and Match() instructions
devmnt: fix mistake in mntrahread()
devsdp: keep cipher states in secret memory
devssl: allocate cipher states in secret memory
devtls, devssl: make sure channel has ORDWR mode and is not a mount chan on fdtochan()
devtls: allocate cipher states in secret memory
ether8169: fix wrong mbps setting (from qu7uux)
etheriwl: add pcid 0x0082 for Intel Centrino Advanced-N 6205 variant
ip/esp: allocate cipher states in secret memory
ip/il: dont attept to connect over IPv6, IL only supports IPv4 packets
kernel: add secalloc() and secfree() functions for secret memory allocation
kernel: dont pprint() into 9p channels
kernel: more (arm) compiler friendly mul64fract()
kernel: switch to fast portable chacha based seed-once random number generator
swap: make sure swap chan has ORDWR mode on fdtochan()
wifi: allocate cipher states in secret memory, do AESstate key setup once


libraries
---------

ape/libap: add d_stat struct in dirent struct allowing the avoidance of stats
ape/libauth: add PASSWDLEN constant to compile passtokey.c from native libauthsrv (thanks lawler)

libmp: allow passing nil to v,x,y results of mpextendedgcd(), simplify mpinvert()
libmp: fix mpnot and add mpasr
libmp: fix mptov and mptouv
libmp: mpdiv: negative divisor has to flip sign of quotient
libmp: mpnrand(), what was i *THINKING*
libmp: mptrunc: don't write to r->p[r->top]
libmp: mptrunc: normalize after mpassign to handle the case b==r
libmp: remove unused mpeuclid.c
libmp: strtomp: fix mpbits() call in octal code
libmp: strtomp: update the returned char* even if there were no characters parsed
libmp: timingsafe sign flip for small power-of-two negative divisor for mpdiv()
libsec: add scrypt password based key derivation function
libsec: chacha: calculate rounds in separate function (helps registerizer), get rid of unrolled code


compiler
--------

5a: ROR instruction
5a: assemble constant >>0 right shifts as <<0 (no shift), allow >>32
5c: do shift propagation for rotate right (ROR)
5c: fix int -> uvlong cast bug (thanks to qwx on his patience on a the trouble session to narrowing it down)
5c: format assembly constant right shift encoding 0 as >>32
5c: handle unused results for cgen64()
5c: support for bit ROR, native 64 bit arithmetic
5l: ROR instruction
5l: format assembly constant right shift encoding 0 as >>32
