Revert "Reintroduce -fstack-protector"

http://lists.freedesktop.org/archives/input-tools/2013-September/000332.html
See above a detailed reasoning, but Colin Walters put it this way:

"At a high level, I think components (git repositories) should feel free
to set up default warning flags and possibly use a targeted subset of
-Werror=foo.  But please don't inject non-warning flags like this unless
there is a very good reason.

The right way to do -fstack-protector is to have something like
redhat-rpm-config or other global CFLAGS system controlling *all*
components."

Thus, reverting the -fstack-protector flag. This doesn't completely address
Colin's comments, we still use a few other flags. But this one is the one
that causes real headaches, so drop it.

This reverts commit f5e65ea3ce2541fe8ccfafe9b0dd04325da75b34.

Add some gcc/ld optimizations and magic

There are several gcc/ld flags that optimize size and performance without
requiring explicit code changes. In no particular order, this adds:
 - gcc -pipe to avoid temporary files and use pipes during compilation
 - gcc -fno-common avoids putting uninitialized global variables not
   marked as "extern" into a common section. This catches compilation
   errors if we didn't mark global variables explicitly as "extern".
 - gcc -fno-strict-aliasing allows us to use unions for some binary magic.
   Otherwise, -O2 might assume that two different types never point at the
   same memory. We currently don't rely on this but it's common practice
   so avoid any non-obvious runtime errors later.
 - gcc -ffunction-sections and -fdata-sections put each function and
   variable into a separate section. This enables ld's --gc-sections to
   drop any unused sections (sections which aren't referenced from an
   exported section). This is very useful to avoid putting dead code into
   DSOs. We can now link any helper function into libevdev and the linker
   removes all of them if they're unused.
 - gcc -fstack-protector adds small stack-corruption protectors in
   functions which have big buffers on the stack (>8bytes). If the
   stack-protectors are corrupted, the process is aborted. This is highly
   useful to debug stack-corruption issues which often are nearly
   impossible to catch without this.
 - ld --as-needed drops all linked libraries that are not actually
   required by libevdev. So we can link to whatever we want and the linker
   will drop everything which is not actually used.
 - ld -z now, resolve symbols during linking, not during runtime.
 - ld -z relro, add relocation-read-only section. This allows to put
   read-only global variables and alike into a read-only section. This is
   useful for variables that need a relocation and thus cannot be
   explicitly put into a read-only section. This option tells the linker
   to mark them read-only after relocations are done. (that's why -z now
   makes sense in combination with this)

All of these options are common in other open-source projects, including
systemd and weston. Don't ask me why they are not marked as default..

Rewrite libevdev_is_event_code to avoid signed/unsigned comparison

Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

Use libevdev_get_event_type_max from libevdev_get_event_code_name

This will check for invalid types for us, and we can do a better check
for signed/unsigned comparison.

Ignore -Woverride-init in event-names.h

Having the declarations in the form of [0...EV_MAX] = NULL together
with the actual definitions causes warnings for every true definition if
-Woverride-init is enabled.

We can drop them for most as they're zero, but still need them for
ev_max (which defaults to -1), not zero. So use the GCC pragma to
disable the warnings for this file.

Change event name generate script to be python 2/3 compatible

Python 3 doesn't have a print statement, only a print function.

Fixed with:
  2to3 make-event-names.py | git apply

Print as function requires Python 2.6 which is reasonable enough given
that even RHEL6 ships that.

Even though it's not needed for 2.6, use
from __future__ import print_function
to avoid accidentally introducing a print statement in the future.
With this line, print "blah" is now a syntax error in python 2.
This line was added manually, after the 2to3 conversion.

Store the abs value after handling mt events

This way any ABS_MT_ event value that comes in will also be stored in abs_info.
That always corresponds to "current slot", so if a user calls
libevdev_set_event_value() or libevdev_get_event_value() they're actually
