to look at the new patch set (#2).

common/main.c: track talloc NULL contexts by default

In order to be able to introspect not only the root application
context, but also all other contexts, e.g. allocated within
libosmocore or other libraries, let's enable tracking the
use of NULL contexts using the corresponding talloc API.

In order to obserbe all existing contexts,
use the following VTY command:

  OsmoBTS# show talloc-context all ...

Example of usage:

  OsmoBTS# show talloc-context all brief

  talloc report on 'null_context' (total 1302808 bytes in 5185 blocks)
    lapd context              contains    129 bytes in   5 blocks
    struct signal_handler     contains     40 bytes in   1 blocks
    struct pcu_sock_state     contains    120 bytes in   1 blocks
    struct lookup_helper      contains     24 bytes in   1 blocks
    struct signal_handler     contains     40 bytes in   1 blocks
    struct signal_handler     contains     40 bytes in   1 blocks
    abis                      contains  49065 bytes in  19 blocks
    struct signal_handler     contains     40 bytes in   1 blocks
    struct signal_handler     contains     40 bytes in   1 blocks
    struct signal_handler     contains     40 bytes in   1 blocks
    vty                       contains  93690 bytes in 5008 blocks
    logging                   contains   2862 bytes in   7 blocks
    OsmoBTS context           contains 1156678 bytes in 137 blocks
