Two arrays are clearly bit maps, so, make that explicit by converting to
bitmap API and remove custom helpers.
Note sig_ind() uses out of boundary bit to (looks like) protect against
potential bitmap_empty() checks for the same bitmap.
This patch removes that since:
1) that didn't guarantee atomicity anyway;
2) the first operation inside the for-loop is set bit in the bitmap
(which effectively makes it non-empty);
3) group_optimization() doesn't utilize possible emptiness of the bitmap
in question.
Thus, if there is a protection needed it should be implemented properly.

With some gcc versions, we get a warning about the eicon driver,
and that currently shows up as the only remaining warning in one
of the build bots:
In file included from ../drivers/isdn/hardware/eicon/message.c:30:0:
eicon/message.c: In function 'mixer_notify_update':
eicon/platform.h:333:18: warning: array subscript is above array bounds [-Warray-bounds]
The code is easily changed to open-code the unusual PUT_WORD() line
causing this to avoid the warning.

I noticed that this function uses a lot of kernel stack when the
"latent entropy" plugin is enabled:
drivers/isdn/hardware/eicon/message.c: In function 'sig_ind':
drivers/isdn/hardware/eicon/message.c:6113:1: error: the frame size of 1168 bytes is larger than 1152 bytes [-Werror=frame-larger-than=]
We currently don't warn about this, as we raise the warning limit
to 2048 bytes in mainline, but I'd like to lower that limit again
in the future, and this function can easily be changed to be more
efficient and avoid that warning, by making some of its local
variables 'const'.

The bug here is that we use "Reject" as the index into the cau_t[] array
in the else path. Since the cau_t[] has 9 elements if Reject == 9 then
we are reading beyond the end of the array.
My understanding of the code is that it's saying that if Reject is 1 or
too high then that's invalid and we should hang up.

In C one can either use '\0' or '\x00' (or '\000') to add a NUL byte to
a string. '\0x00' isn't part of these and will in fact result in a
single NUL followed by "x00". This fixes that.

isdn source code uses a not-current coding style.
Update the coding style used on a per-line basis
so that git diff -w shows only elided blank lines
at EOF.
Done with emacs and some scripts and some typing.
Built x86 allyesconfig.

When compiling this driver, the compiler throws the following warnings:
drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds
This arises from the particular semantics the driver is using to write to
the nlc array (static byte[256]). The array has a length in byte 0
followed by a T30_INFO struct starting at byte 1.
The T30_INFO struct has a number of variable length strings after the
station_id entry, which cannot be explicitly defined in the struct and the
driver accesses them with an array index to station_id beyond the length
of station_id.
This patch merely changes the semantics that the driver uses to access the
entries after the station_id entry to use the original 256 byte nlc array
taking the offset and length of the station_id entry to calculate where to
write in the array, thereby silencing the warning.

Use offsetof instead of explicit implementation.
* fixes bug with omitted & like:
len = (byte)(((T30_INFO *) 0)->station_id + 20)
* avoids compiler warnings with wrong sizes (pointer-to-char cast):
len = (byte)(&(((T30_INFO *) 0)->universal_6));
* cleans up the code

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
