- Add ' to the list of directly encoded characters and * to the list of
optionally directly encoded characters as per RFC 2152.
- In _citrus_UTF7_mbtoutf16 on end of input when the next output character
has only been partially decoded, save a copy of the buffer of input
characters (not just its length). On the next call with more input
characters this buffer is reprocessed together with the new input to
form a fully decoded output character.
- At the end of a base64 encoded sequence fully discard '-' (BASE64_OUT)
by decrementing psenc->chlen and i. This is needed to make room in
psenc->ch (input buffer) in case the next input character starts a new
base64 encoded sequence. And also, if this is the end of input and no
output character can be returned, this brings the encoder in the initial
state as indicated by _citrus_UTF7_stdenc_get_state_desc_generic which
is used by the caller to distinguish between no output and partial
output.
- In _citrus_UTF7_mbrtowc_priv pass the s parameter (input pointer)
directly to _citrus_UTF7_mbtoutf16 instead of a copy (s0). This way s
is updated correctly in case of errors.

SVN 283406: Fix decoding of UTF-7 when a base64 encoded chunk appears at
the end of the input buffer.
_citrus_UTF7_mbtoutf16 stored the decoder state at the beginning so it
could restore this state on an incomplete character such that the next
call would restart the decoding. The problem was that "-" (end of base64
mode) at the end of a string was also treated as an incomplete character
but was also removed from the state buffer. So the initial state would be
restored (with base64 mode) and the next call would no longer see the "-"
so it continued in base64 mode.
This state saving/restoring isn't needed here. It's already handled
elsewhere (citrus_iconv_std.c:_citrus_iconv_std_iconv_convert) so just
remove it.

kernel - Improve basic entropy collector
* Faster time-buffered period in first 120 seconds after boot to help seed
the generator. This helps when other sources such as RDRAND are not available.
* Use a systimer instead of tsleep to make the 'random' loop delay more random.
* Do a better job incorporating interrupt randomness with a combination of
counter and low TSC bits.
* Get rid of the double-time-buffering restrictions (one in the thread, one in
NANOUP_EVENT(). Also incorporate the low TSC bits in different bit positions
to try to avoid XOR deconstruction against tv_nsec.

drm - Used fixed start address instead of vm_map_hint() in i915_gem_mmap_ioctl()
* We tried to fix i915_gem_mmap_ioctl() returning a valid 'NULL' address for
the requested mapping by passing the vm_map_hint() address into it. This
worked, but for reasons unknown wound up destabilizing X11 itself.
* So, instead of using 0, and instead of using vm_map_hint(), the 'hint'
starting address is now fixed at PAGE_SIZE (0x0000000000001000). And this
seems to solve the destabilization.

hammer2 - xop stabilization - part 2/many
* The xop mechanics do a quorum calculation, and will also do quorum
calculations for the inode cluster (not yet in). This calculation is
primarily based on the bref.modify_tid.
Each backend XOP now needs its own modify_tid to properly distinguish
between and eventually serialize dependent backend ops.
* Implement discrete modify_tid (mtid) reservations in
hammer2_xop_alloc(). Remove the old modify_tid reservation code that only
incremented it on a per-flush basis.
* The flush code will acquire a unique modify_tid which is greater than all
prior modify_tids in stage 2 (after it clears PREFLUSH).
* The hammer2_xop_alloc() code is too messy returning the union structure,
return a void * instead so the caller can just assign it to the correct
sub-union structure.
