linker: q: attempt to get TLS relocations to work 82209cb0d8

linker: q: implement lazy TLS initialization for StaticTls modules 5a6510a25f

While Bionic's StaticTls is normally only for the main
executable, libhybris attempts to utilize it for dlopened libraries
by using a pre-allocated thread-local array.

Because all libraries are dlopened, only the calling thread initializes
its static TLS. Other existing threads need a way to detect and setup
these new TLS segments.

This change adds generation-aware lazy initialization by adding
a generation check to tlsdesc_resolver_static. It compares the
thread's DTV generation with the global generation. If it is stale,
it uses a register-preserving slow path, which calls
hybris_linker_tls_init_thread.

hybris_linker_tls_init_thread function synchronizes the thread's DTV
and performs a static TLS initialization only for modules loaded after
the thread's last sync.

This prevents overwriting TLS data that the thread already modified
in older modules.

linker: q: fix A16 TLS struct compat for tls-relocs 6d3294c617

- Add overflowed() to A16 StaticTlsLayout (needed by register_soinfo_tls)
- Fix finish_layout() to use A16 field names (cursor_/align_ vs offset_/alignment_)
- Add overflow tracking to A16 reserve()
- Remove CHECK(static_offset == SIZE_MAX) in unregister_tls_module —
  hybris assigns static offsets to all modules via hybris_tls_storage

linker: q: add /vendor/lib64/hw to default LD paths 7e7b66c5a0

AIDL gralloc mapper (Gralloc5) loads mapper.pixel.so via
android_load_sphal_library which searches the default linker
paths. The library lives in /vendor/lib64/hw/ which wasn't
in the search list.

hooks: use initial-exec TLS model for hybris_tls_storage 76c0a6a5fd

Without initial-exec, hybris_tls_storage uses TLSDESC (dynamic TLS)
which means the TP offset varies per thread depending on when the
TLSDESC resolver runs. This causes crashes when the compositor's
Mali shader compiler thread hits the slow path.

With initial-exec, the TP offset is fixed at load time and constant
across all threads. Requires LD_PRELOAD to reserve static TLS space
when the library is dlopen'd (handled by lsc-wrapper).
