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
