Reduce memory requirement for MT syncing

Changes the algorithm: before we'd ioctl all axes for all slots, then generate
events for all slots one-by-one.

Now we ioctl the slot state for each axis, copy the new event value into
the device and mark a bitfield that we've updated the value. Then loop through
the slots and generate events where changed.

Side-effect: this makes it easy to check if anything in the slot has updated,
so we can skip empty slot events during sync.

Min memory requirement for the state storage was:
  MAX_SLOTS  * (ABS_MT_CNT + 1) * sizeof(int) = 1980
Min memory requirement now:
  (ABS_MT_CNT + 1) * sizeof(int) + NLONGS((MAX_SLOTS * ABS_MT_CNT) bits) = 544

This is sigsafe code, so this was stack memory. Reducing the requirement
allows us to up MAX_SLOTS in the future if we need to.

Add ld version-script

Explicit symbol versioning allows us to provide multiple versions of
incompatible API changes. It is a very common practice in GNU world and
avoids the problems occuring if distributions try to ship multiple version
of a single DSO.

Background information available at:
  http://people.redhat.com/drepper/dsohowto.pdf

To see the symbol-versions, use objdump:
  objdump -T libevdev/.libs/libevdev.so.1.0.0
This can also be used to verify that all symbols are correctly
exported (typos in linker-scripts are silently ignored by ld).

user that they're not fast enough handling this device.

The test for this is rather complicated since we can't write SYN_DROPPED

autogen.sh: remove unneeded m4 configuration workaround

Creating the m4 directory is not required under any circumstances
when the package is properly configured. We have git files under m4.

Review/update .gitignore files

Merge potentially useful patterns taken from other projects.

Some application specific patterns were move to their respective directories.

The only noticeable change is that *.patch is ignore to prevent accidental
checkin of patches. The pattern "test-driver" could not be found and was
removed.

The test directory had not been updated since the move of all test cases
in a single binary.
