GCC would remove inline asm due to lack of knowledge
of FPU register changes.

AI_ADDRCONFIG is currently implemented by trying to connect
to well-known addresses in order to see if IPv4 and/or IPv6
connectivity is available.
In some cases (e.g., walled gardens with no global
connectivity) both probes can fail. If this happens,
query for both IPv4 and IPv6 addresses instead of doing
nothing and failing the query.

Change Ife82a8d8 broke IPv6 on wifi. Change I4e3a69ea is
an alternate approach that does not require any framework
changes.

Instead of checking for IPv4 or IPv6 connectivity, try using pid-specific
hints the framework has left for us.

vfork() would not save the registers that the parent would expect
to have restored after execl() completed.
Specially that execl() would call execve() underneath, further messing
up the stack of the parent.
To avoid that, we fork() for now. Later we will revisit and cleanup
vfork()+execve() to actually have vfork() store all the register
that the parent expects to see, and not those left by execve().
In the original code, looking at the registers just before the call to
popen(), and after the call showed that r7 would get clobbered.
This would leave the caller with an invalid pointer, leading to all
kinds of data corruptions.
execve() is simpler that execl() in this case.

In 48527c3f74, we modified the soinfo
structure to remove an unnecessary variable. However, third party
programs seem to be relying on the structure not changing.
Add a dummy variable back into place to preserve structure.

This patch allows the debugging of constructors in shared
libraries and executables. It does so by ensuring that the
corresponding binary is visible to gdb before running the
constructors.

This patch ensure that __aeabi_f2uiz is embedded in our C library.
This is needed to avoid breaking certain applications when they are
loaded in ICS. It is likely that the issue is due to mis-linked
binaries generated with the stand-alone toolchain (the problem
should not exist if you use ndk-build), but this fix is easier
than asking all app developers to fix their custom build system.

sincos() functions would be turned into infinite calls to
itself if sincos optimization is applied to itself. See
gcc bugzilla http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46926
arm-linux-androideabi-4.4.3 toolchain does not have this problem
because sincos optimization is entirely disabled. Starting
from arm-linux-androideabi-4.6 toolchain, we enable sincos optimization
in gcc.
This patch simply enforce -O0 on this function to minimize the
change.
