When the linker was changed so that it put a read-only map and
read-execute map, this code incorrectly computed the relative pc and
offset. Modify to look for the actual start map in this case.
Also, change the load_base name to load_bias.

Test: Dumped logcat while dumping backtraces.

This test didn't clear errno before testing it, so was sensitive to
whatever code had run before. Since I'd already added the code to dump
the exact kernel version before realizing the actual bug, I've left that
in too.

Using rint(3) gave us a step where if one side was 1.4 and the other
was 1.5, that would be 1 and 2 respectively. So instead use a simple
difference. Also log more detail in case this doesn't fix the flakiness.

This includes:
- Blocks allocated by small object allocators are now aligned to
their block size.
- Remove redundant free_blocks_cnt and allocated_blocks_cnt, as they
sum up to a fixed number.
- Remove a redundant padding word in small_object_page_info on 32-bit
platform.
Test: Build and boot cuttlefish.

The current implementation of LinkerSmallObjectAllocator keeps record
of pages in a vector, which uses its own page(s). This is at least a
page overhead per LinkerSmallObjectAllocator.
This change removes the page record vector by managing the pages in a
doubly linked list.
We also fix a bug where we are actually keeping up to 2 free pages
instead of just one.
The memory used by small objects when running 'dd', before this change:
72 KB [anon:linker_alloc_small_objects]
28 KB [anon:linker_alloc_vector]
After this change:
60 KB [anon:linker_alloc_small_objects]
Test: Boot cuttlefish and check memory used by linker.

This slot will replace TLS_SLOT_TSAN, which needs to be removed for ELF
TLS compatibility. The platform has both slots reserved until compiler-rt
can be updated. See:

This change is intended to allow native-bridge to use independent
TLS memory for host and guest environments, while still sharing a
thread-local errno between the two.

Look for the tzdata file in the runtime module before looking
in /system. It is still an open question how the removal of
tzdata will be handled, if at all. Until it is worked out it
will be duplicated.

The same prebuilts will be used in both runtime and time zone
modules. Having the rules put the files in etc/tz/ will make
them more appropriate for the runtime module.

* changes:
Replace TLS_SLOT_BIONIC_PREINIT w/ shared globals
Use shared globals so getauxval works earlier
Split main thread init into early+late functions
Add filegroups for libc sources not included in component static
libraries.
