* This is a minimal convertion -- everything compiles and looks OK.
* We print a warning for spans registering without a spantype.
* Low-level drivers may later want (but not required)
to fold their internal representations to this canonical
representation -- it will save code and make it more readable.

In addition to updating the year, this also adds some boilerplate to
dahdi-sysfs.c and dahdi-sysfs-chan.c that wasn't there previously.

This removes the following warning:
Section mismatch in reference from the function init_module() to the function .exit.text:dahdi_sysfs_exit()
The function __init init_module() references a function __exit
dahdi_sysfs_exit(). This is often seen when error handling in the init
function uses functionality in the exit path. The fix is often to remove the
__exit annotation of dahdi_sysfs_exit() so it may be used outside an exit
section.

This patch removes support for kernel versions < 2.6.18, as those are
not actively supported in any major Linux distribution (except RHEL4,
which is in the "extended" support level of the product life cycle).
This removes much of the more #ifdef-rich parts of the code.

* Shortcut CLASS_DEV_CREATE/CLASS_DEV_DESTROY. No need to pass repetitive
data (and NULL) on every call.
* Create/remove fixed device files (ctl, timer, channel, pseudo) via
generic code (fixed_devfiles_create()/fixed_devfiles_remove()) instead
of repetitive code and flags.
* Try to make all removal/cleanup functions idempotent, so we can
safely call them on any failure without the need for multiple goto
destinations.
* Rename 'device_state_flags' to 'should_cleanup' and its member
flags to a better/consistent naming.
* Rename dahdi_sysfs_exit() to dahdi_sysfs_cleanup() and call it from
a new proper dahdi_sysfs_exit()
* In dahdi_sysfs_init(), handle dahdi_sysfs_chan_init() failures
* Add dahdi_dbg() message before creating/removing all DEVICES
objects.
* Also move two KERN_INFO messages to a more correct locations:
- The version reporting should be first (in dahdi-base.c)
- The "Telephony... on major" reporting should be at the end
of dahdi_sysfs_init()

This patch exposes the span 'lineconfig' via sysfs: textual representation
of the framing and coding of the span.
This is needed in order for the Dahdi perl classes (in tools) to get
the inforamtion for e.g. dahdi_genconf to work without the guesswork of
parsing /proc/dahdi .

* A parent-less device should not crash dahdi:
- Access span->parent->dev instead of span->parent-dev.parent
in soem cases.
- Access span->parent->dev via new inline span_device()
- Use span_device() in all dahdi_dev_{dbg,info}()
* Allow low-level drivers to set their device name.
- Drivers that don't use this feature get the default name
based on the parent device name
- Parent-less devices which don't set their name, fails
to register with -EINVAL

For some boards, the linemode (E1/T1/J1) is software selectable but
needs to be configured before the spans were historically registered
since the line mode determines the channel count available on the span.
This change exports a "spantype" attribute from the dahdi_device that
can be used to set E1/T1/J1 before the spans are assigned. When
userspace writes to this attribute (in a <span offset>:<span type
string> format), and if the board driver has implemented a set_spantype
function in it's dahdi_span_ops, then the board driver can optionally
change it's mode before registration.
Also part of this change is breaking out the raw data structure
initialization of the spans / channels via the dahdi_init_device_spans
function since the board drivers may need to reallocate channels / spans
as part of this callback. For example, changing from T1 to E1 mode will
require allocating 7 new channels.

'irqmisses' is more a function of the device and there are better ways

This exposes dahdi devices in sysfs and also exposes attributes that
will allow user space to control the registration order in spans. This
facilitates loading drivers out of order yet keeping consistent
span/channel numbering, which in turn will eventually allow the
blacklist for DAHDI drivers to be removed. The default behavior,
controlled with the auto_register module parameter on dahdi is to number
the spans / channels in order like is currently done. So this change
does not introduce any new behavior by default.
* Writing (anything) to this attribute returns the span to its
unassigned state
* Fix dahdi_chan_unreg() echocan refcount
* Add safeguard against duplicate unassignment to _dahdi_unregister_span()
* Remove the span from device_node list, only in dahdi_unregister_device()
and not in dahdi_unregister_span()
* Free allocated span->span_device in span_sysfs_remove()

dahdi: Add "hardware_id" dahdi_device attribute.
- The "hardware_id" does not change with device location (e.g: when a PCI
card is moved from one slot to another).
- Not all devices have this attribute. It is legal for it to be NULL (that
is the default for all low-level drivers that do not set it explicitly).
- When "hardware_id" is NULL, the sysfs attribute value is "\n"

This moves the version string into dahdi-version.c that is then linked into
dahdi-base.c and dahdi-sysfs.c. This speeds builds on slow computers since
dahdi-base.c and dahdi-sysfs.c does not need to be rebuilt if only the version
string is changing.
