perf dlfilter: Avoid leak in v0 API test use of resolve_address()
The introduction of reference counting causes the v0 API perf_dlfilter_fns.resolve_address() to leak.
v2 API introduced perf_dlfilter_fns.al_cleanup() to prevent that.
For the v0 API, avoid the leak by exiting the addr_location immediately, since the documentation makes it clear that pointers obtained via perf_dlfilter_fns are not necessarily valid (dereferenceable) after 'filter_event' and 'filter_event_early' return.

perf addr_location: Add init/exit/copy functions
struct addr_location holds references to multiple reference counted objects. Add init/exit functions to make maintenance of those more consistent with the rest of the code and to try to avoid leaks. Modification of thread reference counts isn't included in this change.
Committer notes:
I needed to initialize result to sample->ip to make sure is set to something, fixing a compile time error, mostly keeping the previous logic as build_alloc_func_list() already does debugging/error prints about what went wrong if it takes the 'goto out'.

perf thread: Add accessor functions for thread
Using accessors will make it easier to add reference count checking in later patches.
Committer notes:
thread->nsinfo wasn't wrapped as it is used together with nsinfo__zput(), where does a trick to set the field with a refcount being dropped to NULL, and that doesn't work well with using thread__nsinfo(thread), that loses the &thread->nsinfo pointer.
When refcount checking is added to 'struct thread', later in this series, nsinfo__zput(RC_CHK_ACCESS(thread)->nsinfo) will be used to check the thread pointer.

perf map: Add accessor for dso
Later changes will add reference count checking for struct map, with dso being the most frequently accessed variable. Add an accessor so that the reference count check is only necessary in one place.
Additional changes: - add a dso variable to avoid repeated map__dso calls. - in builtin-mem.c dump_raw_samples, code only partially tested for dso == NULL. Make the possibility of NULL consistent. - in thread.c thread__memcpy fix use of spaces and use tabs.

perf script: Add API for filtering via dynamically loaded shared object
In some cases, users want to filter very large amounts of data (e.g. from AUX area tracing like Intel PT) looking for something specific. While scripting such as Python can be used, Python is 10 to 20 times slower than C. So define a C API so that custom filters can be written and loaded.
