We have to free TDs more carefully if they have been processed by the

them back to the done queue, but that seems wrong. We can't be sure,
when they get written back. This resulted in leaking TDs with an invalid
reference to a freed interrupt queue.
The new approach: Mark the interrupt queue to be destroyed and handle
the freeing later, when the controller posted the last TD to the done

The linking of interrupt queues into UHCI controller's framelist (in
uhci_create_intr_queue()) was incomplete. The implementation of
uhci_destroy_intr_queue() was even worse, looking like it wanted to
clean up more than uhci_create_intr_queue() did.
This patch follows the simple approach that we used for OHCI and EHCI:
Each slot in the framelist holds only one interrupt queue. Therefore, we
have to look for free slots each time we want to link an interrupt queue
into the framelist. In return, we have a much simpler structured
framelist.
With this, USB devices using interrupt transfers (e.g. keyboards) can be
detached cleanly from UHCI controllers. Also, more than one of such
devices can be attached without further risk.

We had mixed virtual and physical pointers in struct sysinfo_t. Some
being virtual by accident which led to problems when we tried to
reinitialize lib_sysinfo after relocating FILO (to get intentionally
virtual pointers valid again). I guess this didn't cause much trouble
before, as lib_get_sysinfo() was always called with physical addresses
being equal to their virtual counterparts.
For FILO, two possibilities seem practical: Either, have all pointers in
struct sysinfo_t physical, so relocation doesn't hurt. Or, have all
pointers virtual and call lib_get_sysinfo() again after relocation.
This patch goes the latter way, changing the following pointers for
situations where virtual pointers differ from physical:
.extra_version
.build
.compile_time
.compile_by
.compile_host
.compile_domain
.compiler
.linker
.assembler
.cb_version
.vdat_addr
.tstamp_table
.cbmem_cons
.mrc_cache
We could also just correct the accidentally virtual pointers. But, IMO,
this would lower the risk of future confusion.
Note 1: Looks like .version gets never set.
Note 2: .option_table and .framebuffer were virtual pointers but treated
like physical ones. Even in FILO, this led to no problems as
they were set before relocation.

hci_t.init().
Warning: This breaks code that relies on the current, special,

afterwards.
