Rename the /usr/share/doc/legal files to driver.LICENSE to work around
bug of installing 'realtek' and 'intel_iwn' as files rather then as
a 'LICENSE' file in their directories.

Also add obsolete entries for the older names and names that existed in head
for a period of time.

- Add Intel firmwares for Intel PRO/Wireless LAN 2100/2200/2915 cards in a
uuencoded format along with their respective LICENSE files.
- Add new share/doc/legal directory to BSD.usr.dist mtree file. This is the
place we install LICENSE files for restricted firmwares.
- Teach firmware(9) and kmod.mk about licensed firmwares. Restricted firmwares
won't load properly unless legal.<name>.license_ack is set to 1, either
via kenv(1) or /boot/loader.conf.
