Rename from LIBEVDEV_READ_foo to LIBEVDEV_READ_FLAG_foo to differentiate

Improved readability in callers, changing magic numbers 0 and 1 to
rc = libevdev_next_event();
if (rc == LIBEVDEV_READ_STATUS_SUCCESS)
do_something();
else if (rc == LIBEVDEV_READ_STATUS_SYNC)
do_something_else()
No ABI changes, the enum values are the previously documented values,
this is just a readability improvement.

Another look at the current API showed some inconsistencies, rectified
in this commit:
libevdev_kernel_*: modify the underlying kernel device
libevdev_event_type_*: something with an event type
libevdev_event_code_*: something with an event code
libevdev_event_*: struct input_event-related functions (i.e. not device-related)
libevdev_property_*: something with a property
libevdev_*: anything applying to a device
Hopefully that's the last API change. Current symbols deprecated and aliased.

The logging we do use atm inside the library is largely
to spot application errors. Log that to stderr by default so
it doesn't get lost.

There's no need to have separate logging function for each device created.
More likely, libevdev will be hooked up once into the logging system and
expected to deal with it.
Plus, this allows us to log from the uinput code where we don't
have the context anyway.
Requires a rename to libevdev_set_log_function to avoid ABI breaks, and
while we're breaking the ABI make the logging function more sophisticated
to log line, number, etc.

From errno(3):
ENOMEM Not enough space (POSIX.1)
ENOSPC No space left on device (POSIX.1)
when we run out memory the reason is a failed malloc, for which ENOMEM
seems more appropriate.

The ioctls return the number of bytes copied into the destination, so just
copy them into the device state instead of individually flipping bits.
For easier review: rc is the return value of the EVIOCG* ioctl, which is
the number of bytes copied.
state variables must be initialized to 0 now, in case the kernel's FOO_MAX
is smaller than libevdev's FOO_MAX. If not initialized to 0, the bytes
between the two max values is undefined and we may end up generating bogus
events.

GCC_CFLAGS was set by configure, but never actually used. So we didn't build with hidden symbols,
rather just weeded them out later through libtool.
Do this properly now, mark the symbols as visibility default.

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
modifying the current slot value.
When the current slot changes, sync the state back into the absinfo values.
