Our dlmalloc implementation currently calls abort() when it detects
that the heap is corrupted, or that an invalid pointer is passed to
one of its functions.
The only way to detect this is because abort() will force-fully
crash the current program with a magic fault address of '0xdeadbaad'.
However, this is not really well documented, and a frequent topic
on the android-ndk forum (among others).
This change makes our dlmalloc code dump a simple message to the
log just before the abort() call (and hence before the stack trace)
to better help identify the problem.

Quote from Linux Programmer's Manual:
"If t is non-NULL, the return value is also stored in the memory

Unfortunately, legacy .so files for ARM don't have a correct crtbegin file.
Consequently, we have to grandfather the old __dso_handle behaviour.
Add some ifdefs for ARM to allow it to use the old code until we can work
out a transition.

This change ensures that operator new will call abort() in case
of memory allocation failure. Note that due to our usage of memory
overcommit, this can only happen under very rare circumstances
(i.e. trying to allocate memory larger than the larger free range
of virtual address space, or when memory is corrutped in various
ways).

Initial commit for dns cache per interface.
Added a type that holds a reference to a
cache and name of associated interface,
address of interface, name server(s)
associated with an interface etc.
New functions to set default interface,
address of name servers etc.

This change fixes the prctl() declaration to match GLibc, and allow us
to build gcc-4.6 for Android (among other things). Note that this does
not change the source and binary interfaces.

Several updates to Bionic crt*.o files to implement Linux/x86
stack unwind/exception handling.
Mark __dso_handle as hidden.
Note: Requires complete rebuild due to CRT changes. Google will
need to regenerate and check-in all the prebuilt x86 CRT object
files and libraries which link to them.

NOTE: This is a back-port from the internal HC branch.
This patch fixes a leak that occurs when creating a new
thread-specific DNS resolver state object.
Essentially, each thread that calls gethostbyname() or getaddrinfo()
at least once will leak a small memory block. Another leak happens
anytime these functions are called after a change of the network
settings.
The leak is insignificant and hard to notice on typical programs.
However, netd tends to create one new thread for each DNS request
it processes, and quickly grows in size after a > 20 hours.
The same problem is seen in other system processes that tend to
create one thread per request too.
The leak occured becasue res_ninit() was called twice when creating
a new thread-specific DNS resolver state in _res_get_thread().
This function could not properly reset an existing thread and was
leaking a memory block.
The patch does two things:
- First, it fixes res_ninit() to prevent any leakage when resetting
the state of a given res_state instance.
- Second, it modifies the _res_get_thread() implementation to
make it more explicit, and avoid calling res_ninit() twice
in a row on first-time creation.

The gethostbyaddr code in system/netd now expects a string address

According to Intel ABI spec, there is no need to save %eax, %ecx, %edx
on the stack. Worse, popping %eax will wipe out the return value.
