* We need to split the BRI D-Channel (HDLC) frames to smaller packets,
limitation of the FPGA.
* This changes batches BRI D-channel packets of the same HDLC frame to a
single XPP frame.
* Avoids an accidental fragmantion in case we were delayed for a few ms-s.
* Also improves efficiency.

* The zero lenth case (Magic request) was split into
send_magic_request() function. It was not possible
to move it into card_bri.c, because it is called
directly from the general interface we provide for
register read/write via sysfs/proc.
* The normal case (send_multibyte_request) was moved from
card_global.c into card_bri.c
* This sets the stage to enable bundling of multibyte
packets into frames (like we do for PCM).

I've seen some platforms that do not properly route the interrupt from the
card to the host CPU. In these cases the card potentially could appear to be
greened up even though no data is flowing over the spans.
This change allows dahdi_cfg to return an error when this occurs, and also
ensures that all the spans are in RED alarm.
For example, dahdi_cfg output when the card is not generating interrupts:
# dahdi_cfg
DAHDI startup failed: Input/output error
And the kernel log will contain a string like:
wct4xxp 0000:02:08.0: Interrupts not detected.

Restores the pri_protocol attribute of the XPD node in SysFS to be
writable. Fixes a minor regression from the pinned-spans fix, similar to
r10334.
* This attribute was made R/O in digium r10280 as part of the
pinned-spans changes:
- The E1/T1 settings were changed via new set_spantype() method
which was called from dahdi when the 'spantype' dahdi attribute
was written to.
- This fails our init_card_4_* trying to write E1/T1 into our private
attribute.
* Restored our old code (with minor modifications) so we
can set E1/T1 the old way (writing to our 'pri_protocol' attribute)
as well as the new way (when it will be used eventually).

This restores a somewhat limited functionality of the "span"
write interface in the SysFS node of the span, broken by the
pinned-spans code.
* PROBLEM: dahdi-linux pinned-spans should work with existing dahdi-tools
specifically the dahdi_registration tool.
* As a result, we should still be able to control dahdi registration
order. However, registration is now in complete devices and not spans
* Restored dahdi_autoreg=[0/1] xpp module parameter:
- It now refers to complete astribanks and not individual spans
* The xpp module sysfs "span" attribute:
- Implemented write method (for dahdi_registration tool)
- The first write of [1/0] to this attribute, registers/unregisters
the complete astribank
- Further writes are ignored (with DBG messages)
* Also, implemented new xbus_is_registered() function
* Once the new dahdi-tools are merged, we should turn deprecation
messages from DBG() to NOTICE()

Since "wctdm24xxp: Probe for and configure modules in parallel." the
check for the VPMADT032 module was moved closer to after when the
interface was initialized. The 200ms timeout did not provide enough
time for the system to settle out after initial start. The result
was that sometimes after a cold boot the driver would fail to detect
any VPMADT032 modules.
This fixes a race condition that is not in any released branches.
