- as per TS 38.321 section 6.1.3.8, power headroom is an unsigned
    integer of 6 bits which translates to
[POWER_HEADROOM_0,...,POWER_HEADROOM_63]
  - as per TS 38.133 section 10.1.17.1.1, each POWER_HEADROOM_x
    represents the range of values in dB
  - "phr" parameter in MAC stats represent the UE power headroom in dB
    => therefore, it is a signed integer

Future KPM measurement extension: as per TS 28.552 section 5.1.1.26.1,
the BinX is within the range [POWER_HEADROOM_0,...,POWER_HEADROOM_63],
so the max number of bins is 64 but please note that it can be < 64 which is left to implementation;
each bin has a value that represents the number of UEs within the dB range of each bin
=> please note that this is a node level measurement

Fix warnings that appear when compiling dev branch with gcc-14 in debug mode

See merge request !49

gcc-14 warns when using FORTIFY_SOURCE in debug builds:

  /usr/include/features.h:414:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp]
  414 | #  warning _FORTIFY_SOURCE requires compiling with optimization (-O)
      |    ^~~~~~~

Use it in release builds instead.

call_process_id is a byte_string_t, but prior to this commit, we
allocate data->len_cpid, which is likely not the right size; instead,
use the sizeof operator to calculate the right size.

This prevents one of these warnings, depending on compiler (version):

  /home/richie/flexric/src/agent/e2_agent.c: In function ‘generate_aindication’:
  /home/richie/flexric/src/agent/e2_agent.c:56:25: warning: allocation of insufficient size ‘8’ for type ‘byte_array_t’ with size ‘16’ [-Walloc-size]
     56 |     ind.call_process_id = malloc(sizeof(data->len_cpid) );
        |                         ^
