FDT: implement fdt_ether_get_addr()
Introduce fdt_ether_get_addr() in fdt_common.c/h that tries standard
DT properties in the correct order and falls back to a random address
when needed. This should be used by ethernet drivers instead of open-coding
the same logic.

fetch: Stop setting an alarm
Now that fetchTimeout works reliably, setting an alarm is not only no

libfetch: Add read buffering
Previously, we would read FTP control connection messages and HTTP
reponse headers one character at a time. Now, we read as much as will
fit in our buffer and look for a newline. If there is data left over,
it will be reused by the next fetch_getln() call. This also requires
the addition of a fetch_bufread() which takes the buffer into account,
otherwise the start of the HTTP response body will be stuck in the
buffer after we read the last line of the header.
This should noticeably improve HTTP performance, especially for small
transfers.

libfetch: Overhaul socket read / write
* Make fetch_ssl_read() and fetch_ssl_write() behave more like read(2)
and write(2), and drop fetch_socket_read() in favor of read(2).
* Don't request POLLERR, it's implied.
* Don't needlessly set errno, it's relatively costly.
* Always check for EAGAIN from writev(2), otherwise we will abort on a
short write instead of proceeding to poll(2).
* Always check for EAGAIN from poll(2) even though it can't happen on
FreeBSD; POSIX says it can, and it might in the future.
* Rewrite fetch_read() and fetch_writev() to be more similar to each
other. The main difference is that a partial read is treated as
success while a partial write is treated as failure.

tail: Allow repetitive or contraditory options
Unlike its GNU counterpart, our tail(1) has always errored out if given

reimplementation. There is no good reason to continue to do so, not
even tradition, since many other commands (including head(1)) simply
apply the rightmost option in cases like this.

kern_thread: Fix i386 p_emuldata KBI assertion
On amd64 there was 4 bytes of padding between the 20-byte p_comm and
(for LP64) 8-byte p_sysent, so the addition of p_execblock just caused
that padding to be eaten up. However, on i386, there was no such
padding, and so the addition of p_execblock rippled through to
p_emuldata.

hidwacom: Add Wacom ExpressKey Remote driver
The Wacom ExpressKey Remote (ACK-411050) is a wireless button pad
with 18 programmable buttons and a touch ring, used as a companion
device with Wacom tablets.
It communicates via a USB wireless receiver (0x056a:0x0331) using a
vendor-specific HID report (ID 0x11).
This driver exposes the device via evdev:
- 18 buttons: BTN_0–BTN_Z, BTN_BASE, BTN_BASE2
- Touch ring position via ABS_WHEEL (0–71; reports 0 on release)
- Pad activity marker via ABS_MISC (set to 15/PAD_DEVICE_ID when
any input is active, 0 when idle that matches Linux wacom driver
convention)
- Remote serial number via MSC_SERIAL (for userland per-remote
identification)
Battery level, charging state, and touch ring mode (3 LEDs, values 0–2)
