02d30ab799 Remove support for kernels older than 2.6.27
There are not any major distributions that are still supporting kernels
older than 2.6.27 so we can remove many typedefs. The primary motivator
for this change is that kernel 5.0 is dropping support for timeval and
it would be ideal if the in-kernel time representation can
standardize on ktime_t, but 2.6.18 did not support the ktime
interface that was needed.

03b3ce1a10 sysfs: new device attribute: registration_time
Add a new sysfs attribute to dahdi_device: registration_time

* Records the time of the device's registration with DAHDI.
* Used by dahdi_auto_assign_compat to assign spans by device
  registration order when backward compatibility needed.

f5d3b35d7b dahdi: Replace drv_attr with drv_groups on kernels > 3.12.
drv_attrs was fully removed from the bus structure in upstream commit
e18945b159a1cdbc031f1d3b0b7e515a33bdcbf7 which was merged into 3.13.

This is necessary to compile dahdi against linux version 3.13.

This makes the order of operations for device removal symmetrical with those for

dd944f3362 sysfs: new driver attribute: master_span
* This changeset adds master_span as an attribute of the span's driver:
  /sys/bus/dahdi_spans/drivers/generic_lowlevel/master_span
* This is mainly used for debugging.
* Reading from it the master span number (or 0 if there is no master
  span).
* Writing a number to it, force specified span to be master
* Existing Alternatives:
  - grep "MASTER" from /proc/dahdi/*
  - cat /sys/bus/dahdi_spans/devices/span-*/is_sync_master

d4c8eb47ac add a 'location' attribute to sysfs (dahdi_device):
* Our user-space previously used the implicit location from the sysfs
  device path of the "dahdi_device".
* However:
  - Sysfs paths are very limited in length.
  - Low-level driver need more control on the location field.
  - For example, it need to be persistant for span_assignments.
* We now export explicitly the 'location' field which is managed by
  low-level drivers.
* We will use this field as the location in span_assignments.

07c9bcecf2 dahdi: Remove __exit annotation from dahdi_sysfs_exit().
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.

308a773fb2 sysfs channels: cleanup device files handling
* 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()

f9c52bb271 dahdi: Allow 'spantype' to be changed before span assignement via sysfs.
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.

a6824019fb dahdi: Expose dahdi devices in sysfs.
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()

This change will facilitate creating rules that will allow spans and channels
to be accessed by named device files instead of by numbers.

d43e2d3ade dahdi: Do not rebuild dahdi-base.c when only updating the version.
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.

69f3c96690 Refactor SysFS code to dahdi-sysfs.c
* Refactor SysFS and device-related code to drivers/dahdi/dahdi-sysfs.c .
* Move common headers to drivers/dahdi/dahdi.h .

This commit merely moves existing code and should have no functional
change.
