  provider: fix registering fbt and rawfbt twice

Now that rawfbt has been integrated into the fbt provider, it no longer
needs to be in the list of providers to call populate() in.

  providers: loop through all providers for discovery

The discovery of probes was tied to the static list of providers that
are called on init.  It should iterate over all providers that are in
fact registered, i.e. the dt_provs hash.

  dof_parser: generic parser framework to support multiple parsers

To prepare for non-DOF section based USDT probe definitions, the data
passed from dtprobed to the USDT data parser is more generic.  The
dof_helper_t structure is passed first, followed by a block count, and
that number of data blocks, passed as a size followed by the content.

  dtprobed: fix probe name debug output

Debug output while reading dof_parsed_t structures was printing the
probe names as provider->provider.name and probe->probe.name, but
probe.name is a 0-separated concatenation of the probe name elements.
It only printed the module name.  Corrected to print the full probe
name.

Also moved it to the proper place (when a new probe is read rather
than for every tracepoint).

  test: Adapt USDT PC search for USDT LTO changes

To check USDT PCs, we looked at disassembly for characteristics that
indicated USDT probes.

With LTO, however, USDT instrumentation has changed.

Therefore, use showUSDT in tst.pidprobes.sh to extract USDT PCs.

Note that tst.pidargs.sh and tst.pidargmap.sh depend on
tst.pidprobes.sh.  Therefore, those tests also benefit from this change.
They do not yet pass, however, since index 0 for args[] is said to be
out of range.
