perf symbol: Remove symbol_name_rb_node
Most perf commands want to sort symbols by name and this is done via an invasive rbtree that on 64-bit systems costs 24 bytes. Sorting the symbols in a DSO by name is optional and not done by default, however, if sorting is requested the 24 bytes is allocated for every symbol.
This change removes the rbtree and uses a sorted array of symbol pointers instead (costing 8 bytes per symbol). As the array is created on demand then there are further memory savings. The complexity of sorting the array and using the rbtree are the same.
To support going to the next symbol, the index of the current symbol needs to be passed around as a pair with the current symbol. This requires some API changes.

perf srcline: Optimize comparision against SRCLINE_UNKNOWN
This is a string constant that gets returned and then strcmp() around, we can instead just do a pointer comparision.
That requires a new global variable to comply with these warnings from some versions of clang and gcc:
41 68.95 fedora:rawhide : FAIL clang version 16.0.4 (Fedora 16.0.4-1.fc39) result of comparison against a string literal is unspecified (use an explicit string comparison function instead) [-Werror,-Wstring-compare] if (start_line != SRCLINE_UNKNOWN && ^ ~~~~~~~~~~~~~~~ 41
Ack comments:
Agreed, the strcmps make me nervous as they won't distinguish heap from a global meaning we could end up with things like pointers to freed memory. The comparison with the global is always going to be same imo.

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.

of there being a missing nsinfo__put now that the accesses are data race free. Fixes test "Lookup mmap thread" when compiled with address sanitizer.

perf tools: Set build-id using build-id header on new mmap records
MMAP records that occur after the build-id header is parsed do not have their build-id set even if the filename matches an entry from the header. Set the build-id on these dsos as long as the MMAP record doesn't have its own build-id set.
This fixes an issue with off target analysis where the local version of a dso is loaded rather than one from ~/.debug via a build-id.
