Bump date for previous.

mark several interfaces as internal, most of which have other exported
APIs for their use.

Use correct macro.

document USBD_MPSAFE and USB_TASKQ_MPSAFE

- remove some comments about only being relevant for usbmp.
- add documentation for usb_rem_task(), and clean up the task doc in
general. be clear about SMP issues for tasks
- bump date

remove a comment about usbmp.

Remove superfluous Pp. New sentence, new line. Remove trailing whitespace.

add doucmentation for usb_{add,rem,init}_task().

add documentation for:
- usbd_alloc_buffer
- usbd_free_buffe
- usbd_get_buffer
- usbd_do_request
- usbd_do_request_flags

begin to document the changes present on the USBMP branch:
- usbd_sync_transfer_sig
- usb_detach_wait
- usb_detach_broadcast

create a new section on device detachment. XXX needs a code example.

gives pipes and transfers their own .Sh section.

document usbd_open_pipe*(). fix some minor errors.

prepare to re-structure a lot of stuff.

greatly expand the discussion on transfers and provide most of the details
needed to alloc, setup, transfer and obtain the status of them.
this takes care of:
- usbd_close_pipe
- usbd_alloc_xfer
- usbd_free_xfer
- usbd_setup{,_default,_isoc}_xfer
- usbd_transfer
- usbd_{bulk,intr}_transfer
- usbd_transfer_sync{,_sig}
- usbd_get_xfer_status
as well as callback and request information.

update the list of functions missing real descriptions. there are about
30 usbdi.h and 35 usbdi_util.h functions remaining.

- add some comments for post-usbmp
- basic documentation for:
usbd_clear_endpoint_toggle()
usbd_device2interface_handle()
usbd_interface2device_handle()
usbd_pipe2device_handle()
usbd_interface2endpoint_descriptor()
usbd_endpoint_count()
- usbd_close_pipe() has documentation already
- bump date

Remove trailing whitespace.

clarify some descriptions. document a couple more functions.
make a big commented list of the functions that are lacking real
descriptions.

fix a broken sentence. bump date.

Move DESCRIPTION below SYNOPSIS.
Remove function descriptions from SYNOPSIS.
Some cleanup while here.
XXX: most functions lack descriptions.

convert the ugly .Bl/.El list of functions to a real one inside the
.Sh SYNOPSIS section.

XXX, the .Sh DESCRIPTION needs to move under the .Sh SYNOPSIS.

document a large chunk of the USB interface. some of this is kind of
generic and depends upon understanding USB itself (and since i don't
really that well, i might have gotten some wrong.)

branches: 1.8.2;
Use .In macro.

Convert TNF licenses to new 2 clause variant

Generate <>& symbolically. I'm avoiding .../dist/... directories for now.

Empty lines vs. .Pp cleanup, and sort sections.

Fix typo and whitespaces.

This is still very incomplete.
