gsm_bts_alloc() ought to do all static initialization, so that e.g. unit tests
can use an initialized bts struct that is fully usable, just not registered at
the gsm_network.
For example, two INIT_LLIST_HEAD() and various system information data pointers
(pointing to proper places within the same bts struct) should definitely never
be omitted.
This fixes the remaining errors of gsm0408_test's SI tests, as revealed by a
sanitizer build using gcc (Debian 7.3.0-12) 7.3.0.
Fixes:
../../../../src/osmo-bsc/src/libbsc/system_information.c:613:3: runtime error: null pointer passed as argument 1, which is declared to never be null
Initializing the bts->si_common.rach_control results in different expected
bytes for SI2. The initialized values are
bts->si_common.rach_control.re = 1; /* no re-establishment */
bts->si_common.rach_control.tx_integer = 9; /* 12 slots spread - 217/115 slots delay */
bts->si_common.rach_control.max_trans = 3; /* 7 retransmissions */
bts->si_common.rach_control.t2 = 4; /* no emergency calls */
Causing a change to e5 04. 04 is t2 = 4, and the remaining values are verified by:
uint8_t re :1,
cell_bar :1,
tx_integer :4,
max_trans :2;
>>> hex(1 + (9 << 2) + (3 << 6))
'0xe5'
