When we have assigned the cn we will use mempcy to copy the one
byte into the target. Use a static assert to assure that the type
have the same size.
warning: dereferencing type-punned pointer will break strict-aliasing rules

The "sms send pending" VTY command did not work due a mismatch
of types. We are specifying a unsigned long long in the query
and provided DBI with a signed integer type. The result was a
failure do find any information.
Change the API to operate on unsigned long long that is matching
the id of the SMS and the Subscriber and the mismatch with the
query string is gone and pending SMS are sent.

This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC

Theses will be useful to know if we can reuse the tuples or if
we should renew. The 'issued' is currently purely informative.

This fixes a DB warning and no need for NUMERIC here.

This is the first step towards supporting actual A3/A8 authentication.

This has the advantage that counters can be added all over the code
very easily, while having only one routine that stores all of the
current counter values to the database. The counters are synced
every 60 seconds, providing relatively fine grained statistics
about the network usage as time passes by.

The previous implementation had some shortcomings:
- If the MIN ID given was not the exact id of the first unsent SMS,
it would try to submit the same sms several time until id++ finally
made id go to the next one.
- If a subscriber had several SMS pending it would try to submit
them individually (only to get rejected because a paging for that
subscriber was already in progress)

- Need to use sms.id for the ORDER BY since 'subscriber' also has 'id'
- Need to add the join clause between 'SMS' and 'subscriber'
- Add a LIMIT 1 (probably no impact for the db size we're dealing with
here, but with large DB and mysql/postgresql this can help the planner)
- (fix a wrong comment in passing ...)

makes printf much easier on 64bit platforms...

For the compiler classmark1 is a struct and the compiler is
unaware that it fits into an unsigned int. Use memcpy to
copy it to a u_int8_t (the compiler should inline this).
dbi_conn_quote_binary_copy works on unsigned char* change
q_apdu to be unsigned char.

tmsi is four octets long, there is no need to make it a string
and then jump through hoops to convert it to a number. Keep the database
using it as a string to benefit from the NULL handling of the db.
Introduce the reserved tmsi which has all bits set to 1 according
to GSM 03.03 ยง2.4 and start checking for it and make sure the db
code will never allocate such a tmsi.

otherwise, SQLite seems to return the wrong data types ?!?

This helps us to analyze data such as RRLP location information for
later analysis.

When starting the first time there are no tables, doing a revision
check will fail and bsc_hack will exit without tables created. Do
the revision check within db_prepare and allow new tables to be
created before.

We are truncating the size and might should simply use a MIN
here to get the returned size or the maximum we can hold..

Fix various warnings about implicit declarations of functions.

The function retrieves the oldest not-yet-sent SM for the given subscriber
|
|
we also implement verification of the database schema number by
using the 'Meta' table.
|
|
we now have the full path from the MS into the database (SUBMIT), as well as
back from the database to the MS (DELIVER). The database gets correctly
updated once a SMS has been successfully delivered.
What's still missing is the periodic scan over all undelivered messages,
trying to deliver them to the respective MS. So far, you have to manually
trigger this on the telnet interface with 'sms send pending 1'

since a subscriber is an element of the gsm_network, we have to ensure
subscr->net is always set correctly. We do this by using gsm_network
as an argument to all functions that resolve or create a subscriber.

For further evaluation/analysis, this patch stores the classmark 1, 2 and 3
values of every equipment in the SQL database. We can use this non-volatile
data to determine the supported features for each handset that we've ever
seen on our network.

* implement ID based lookup of gsm_subscriber from database
* look-up recipient and sender subscribers from database
|
|
* describe data structures in gsm_04_11.h
* increae LCHAN RELEASE TIMEOUT for case of long SMS
* convert header field in sql table from NUMERIC to BLOB
* initial handling for validity period
* send RP ERROR messages with meaningful RP CAUSE in case of error
