main: add and use root talloc ctx

Create hlr_ctx and pass on to DB and GSUP server code.
Add call msgb_talloc_ctx_init(hlr_ctx).

Instead of printing the entire talloc context on exit, just print the hlr_ctx
upon SIGUSR1 (like our other binaries do). Otherwise we will get pages of
talloc output on each program exit as soon as we add a VTY (next patch).
