10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

- Move all USB device ID arrays into so-called sections,
sorted according to the mode which they support:
host, device or dual mode
- Add generic tool to extract these data:
tools/bus_autoconf

Change USB_DEBUG to #ifdef and allow it to be turned off. Previously this had
the illusion of a tunable setting but was always turned on regardless.

Improve response to multi-touch taps.

Submitted by: Rohit Grover <rgrover1 at gmail.com>

Early-generation touchpads do not send periodic calibration frames for
baseline subtraction, and are very temperature sensitive, so would slowly
drift out of a calibrated state when under load. Escape this by taking
the last frame before we decide that the pad is idle as a finger-free
baseline.

Tested on: iBook G4
