After forking, the kernel_id field in the phtread_internal_t returned by pthread_self()
is incorrect --- it's the tid from the parent, not the new tid of the
child.
The root cause is that: currently the kernel_id is set by
_init_thread(), which is called in 2 cases:
(1) called by __libc_init_common(). That happens when the execv( ) is
called after fork( ). But when the zygote tries to fork the android
application, the child application doesn't call execv( ), instread, it
tries to call the Java main method directly.
(2) called by pthread_create(). That happens when a new thread is
created.
For the lead thread which is the thread created by fork(), it should
call execv() but it doesn't, as described in (1) above. So its kernel_id
will inherit the parent's kernel_id.
Fixed it in this patch.

If we catch a fatal signal that won't automatically re-throw when
the thread resumes, re-throw it manually. (Common examples are
SIGPIPE and the SIGFPE from integer division by zero.)

This reverts commit 94a85f6636
There is a smoke test failure for Prime but Crespo/Stingray are fine. Will revert the change for now until further investigation is made.
Update wire protocol to return and process error code first.
This will make sure dns proxy operations do not stall when
an internal error happens.
Also fix a compiler warning.
Also fix a potential buffer overflow.
And use correct types (uint32_t) rather than int when reading from network.

This adds the thread id and name to the "Fatal signal" logging,
making it easier to track down where in process it actually crashed.

Add support for PT_GNU_RELRO. This allows the static linker to
indicate that certain regions of memory should be marked as
"read-only" after dynamic linking is complete.
See:
* http://www.akkadia.org/drepper/nonselsec.pdf (section 6)
* http://tk-blog.blogspot.com/2009/02/relro-not-so-well-known-memory.html
Note that this change has no effect on Android right now, because
we don't compile our code with relro enabled.

Use the same pattern in atexit.S to reference __dso_handle in a way that
doesn't require a TEXTREL flag to be set.

Summer time in Cuba has been delayed 3 weeks (now starts April 1 rather
than March 11). Since March 11 (the old start date, as listed in 2012a)
is just a little over a week away, this change is urgent.

From the notes:
Chile 2011/2012 and 2012/2013 summer time date adjustments.
Falkland Islands onto permanent summer time (we're assuming for the
foreseeable future, though 2012 is all we're fairly certain of.)
Armenia has abolished Summer Time.
Tokelau jumped the International Date Line back last December
(just the same as their near neighbour, Samoa).
America/Creston is a new zone for a small area of British Columbia
