We don't want the file to be left open after any fork/exec, and we don't
want the read to be blocking; so open it as such.

No real changes for the non-tablet code, but for tablets we now keep the
libwacom datbase around. The primary motivating factor here is response time
during tests - initializing the database under valgrind took longer than the
proximity timeouts and caused random test case failures when a proximity out
was triggered before we even got to process the first event.
This is unfortunately a burden on the runtime now since we keep libwacom
around whenever a tablet is connected. Not much of an impact though, I
suspect, chances are you're running a web browser and everything pales against
that anyway.

Use the same blurb everywhere, changing from the old style MIT to the Expat
license we're using everywhere else.

There's no guarantee that libinput does the right thing if memory allocation
fails and it's such a niche case on the systems we're targeting that it just
doesn't matter. Simply abort if zalloc ever fails.

Prefix device log messages with the device's sysname so it's more obvious
where the messages are coming from. This makes it much easier to grep for a
specific device's messages but also adds some identifier to messages that
were previously without any identifier (e.g. all the state machine debugging)
All info and error messages also automatically prefix the device name, so
those messages are standardised too, e.g
an info message now:
event4 - SynPS/2 Synaptics TouchPad: is tagged by udev as: Touchpad
a debug message now:
event4 - using pressure-based touch detection
And since this required changing a lot of the strings in messages anyway,
polish a few minor things too.

We don't init the required /sysfs files, so let's not spew a lot of warnings
during the test suite.

For each device open the various led devices (brightness only) and map the one
nonzero brightness to the current mode.

Until the kernel patches to handle LED group switching are in place we provide
the external API backed by an implementation that simply exposes one group
with one mode and no toggle buttons. This allows us to ship a libinput release
with the API in place and switch libinput later without having all the stack
above us being delayed.
