Since e19d702b8e, dlsym and friends use recursive mutexes that
require the current thread id, which is not available before the libc
constructor. This prevents us from using dlsym() in .preinit_array.
This change moves TLS initialization from libc constructor to the earliest
possible point - immediately after linker itself is relocated. As a result,
pthread_internal_t for the initial thread is available from the start.
As a bonus, values stored in TLS in .preinit_array are not lost when libc is
initialized.

The END macro was put too far down which made the linker complain about
it. Move up to the end of the code.

Marking segments read-only was pushing the alignment of __on_dlclose by
2 bytes making it unaligned. This change makes sure the ARM code is
aligned to the 4 byte boundary.

This reverts commit 61ff83475c.
This code is harmless, and only applies to the linker, so
there's no harm in keeping it in the tree a little bit longer.
Let's roll this back while we try to figure out the root cause
of bug 6314858.

This change fixes a segmentation fault in the libc unwinder when it goes
past __libc_init.
Unwind instructions for __libc_init direct it to grab the return address from
the stack frame. Without this change, the unwinder gets a wild address and
looks up further unwind instructions for the routine at that address. If it's
unlucky enough to hit an existing function, it will try to unwind it. Bad
things happen then.
With this change, the return address always points to the _start function,
which does not have unwind instructions associated with it. This stop the
unwind process.
__libc_init never returns, so this does not affect program execution, other
than adding 4 bytes on the main thread stack.

Currently we will get the wrong result as follows:
remquof(0x7bb33336, 0x63000000) = -671088640, 0x00000000
remquo(0xbff0000000000003, 0x3ff0000000000003) = 1, 0x8000000000000000
remquo(0x9120000000000001, 0x0000000000000005) = -1288490188, 0x0000000000000004
while the correct one should be:
remquof(0x7bb33336, 0x63000000) = 1476395008, 0x00000000
remquo(0xbff0000000000003, 0x3ff0000000000003) = -1, 0x8000000000000000
remquo(0x9120000000000001, 0x0000000000000005) = -1288490189, 0x0000000000000001
Fixed in this patch.

The ARM static linker wasn't properly handling __exidx_start
and __exidx_end symbols. Now that the static linker has been fixed,
we don't need the dynamic linker to work around this problem.

Compile the linker with -fvisibility=hidden. This reduces the number
of symbols that show up in the .dynsym section of the linker.
These symbols are never exported to other applications.
In particular, this fixes a problem with setting -DLINKER_DEBUG=1
introduced in 468319ce4f.
Because the symbols "debug_verbosity" and "format_log" have not been
resolved before the linker links itself, any attempt to call
PRINT / INFO / TRACE / WARN / ERROR will result in a segfault.
This change allows the static linker to produce a relative reference
to these symbols rather than relying on relocation.
This also has a nice side effect of making the linker slightly smaller
and slightly more optimized.
The following symbols no longer in the .dynsym section of the linker
after this change:
-addr_to_name
-call_constructors_recursi
-calloc
-debugger_init
-debugger_signal_handler
-debug_verbosity
-dladdr
-dlclose
-dlerror
-dl_lock
-dlopen
-dlsym
-dl_unwind_find_exidx
-find_containing_library
-find_containing_symbol
-find_library
-format_buffer
-free
-libdl_info
-linker_env_get
-linker_env_init
-linker_env_secure
-linker_env_unset
-linker_get_error
-__linker_init
-lookup
-lookup_in_library
-malloc
-notify_gdb_of_libraries
-notify_gdb_of_load
-notify_gdb_of_unload
-realloc
-rtld_db_dlactivity
-unload_library
-vsnprintf

From the release notes:
africa
Summer time changes for Morocco (to start late April 2012)
asia
Changes for 2012 for Gaza & the West Bank (Hebron) and Syria
northamerica
Haiti following US/Canada rules for 2012 (and we're assuming,
for now anyway, for the future).
Also include a change made internally to the 'generate' script as part of
the tzdata2011m update that apparently never made it to AOSP; the original
checkin comment for which was:
Update to tzdata2011m.
Fixes for Europe/Tiraspol (Moldova) and all four Ukrainian zones.
Also show the MD5 of the downloaded data, for comparison against the MD5
given in the announcement mails. (There's a plan to move to proper signing,
but that's not implemented on their end yet.)
(I'm repeating the tzdata change for the convenience of anyone grepping the
log, since the 2012 tzdata releases also contain the 2011m changes; 2011m
is the only missing release I noticed.)
