Andreas.Eversberg eaac0cfe77 gsm/gsm48_ie: Fix other range format decoding
As it turns out, the other range were affected too, so Anreas wrote
the fix for them as well.

Sylvain Munaut 71fd42fede gsm/gsm48_ie: Fix Range 256 format decoding
From the mail:

---
appended is another patch for fixing a bug in the calculation of the
frequency lists. This time the patch is for the "Range 256 format".
The problem is that the operand for the "smod" operation might be
negative, in this case the simplified version won't work as expected.

In the patch I introduced a separate function for "smod" which takes
care of the sign. I have not yet checked if the other formats are also
affected, this would be the case if the "smod" operand can be negative.

There might be other solutions to fix the problem without the need
for a separate function, however I have not thought further about it.

A test vector is the following frequency list ("Range 256 format",
first byte is the length):

 09 8b 1c 83 8c 15 ef 02 2d 30

The correct ARFCNs are

 569 571 576 578 586 608 712 715 719

The uncorrected version would instead return:

 444 457 460 464 569 576 578 586 608

This means four ARFCNs are wrong which will cause problems if for
example the frequency list contains the ARFCNs for hopping.

Dennis Wehrle 291e61346b sms: SMS where cropped (from VTY), concatenation of SMS where not possible
Additionally it wasn't possible to send concatenated sms from the vty.
To send multiple sms, it is necessary to use padding bits and add a user_data_header.
Therefore the gsm_7bit_encode function was splitted to gsm_7bit_encode and gsm_septets2octets.
gsm_septets2octets: this is the old gsm_7bit_encode function + additional padding parameter

Additionally the gsm_7bit_decode function was modified to take account for the user_data_header.
With the new gsm_get_octet_len function you can get the octet length for a given septet length.

I also added several sms tests.

This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.

This has been proposed by Harald Welte and Sylvain Munaunt.

Pablo Neira Ayuso fba495e5f6 This patch moves the GSM-specific functions to the new library
libosmogsm which is provided by libosmocore.

I have also moved generate_backtrace() to backtrace.c instead
of gsm_utils.c, otherwise the timer and msgfile tests depend on
libosmogsm.
