The problem was due to the fact that, in the case of dynamic executables,
the dynamic linker calls the DT_PREINIT_ARRAY, DT_INIT and DT_INIT_ARRAY
constructors when loading shared libraries and dynamic executables,
*before* calling the executable's entry point (i.e. arch-$ARCH/bionic/crtbegin_dynamic.c)
which in turns call __libc_init() in libc.so, as defined by bionic/libc_init_dynamic.c

The latter did call these constructors array again, mistakenly.

The patch also updates the documentation of many related functions.

Also adds a new section to linker/README.TXT explaining restrictions on
C library usage.

The patch has been tested on a Dream for stability issues with
proprietary blobs:

- H264 decoding works
- Camera + Video recording works
- GPS works
- Sensors work

The tests in system/extra/tests/bionic/libc/common/test_static_cpp_mutex.cpp has been
run and shows the static C++ constructor being called only once.

Changed it so that when the linker generates error messages, they are
scribbled away into a buffer that dlfcn and friends can read from.

Since the error messages are generetad with snprintf, and snprintf
MAY call malloc during some code paths, we now link against a version
of libc that does not contain malloc/free/realloc/calloc. We then define
malloc and friends in the dynamic loader, and make them abort() if they
are ever called.

For now, this will only used by the dynamic loader to ensure that
malloc and friends are never called.

Removes a lot of redundant code, and reorganizes the file. We first
setup all the comomn variables we may need, and then define the
actual libraries that need to be generated.

* changes:
  Fix getservent() so that it returns s_port in network byte order. Also add a new document detailing known issues in the C library.

* changes:
  Fix __eabi_atexit() implementation, as well as a bug in the BSD-originated __cxa_finalize() implementation This patch uses "#if ANDROID" instead of "#if 1" in the __cxa_finalize() fix

Also add a new document detailing known issues in the C library.

Also add a small design overview document for the linker. The latter contains details on
how the initialization/finalization is supposed to work.

Also update tools/update_all.py to not use perforce add/edit/delete commands automatically now that we're using git

Fix __eabi_atexit() implementation, as well as a bug in the BSD-originated __cxa_finalize() implementation
This patch uses "#if ANDROID" instead of "#if 1" in the __cxa_finalize() fix

This is needed for upcoming STLport experimentation.

revert to previous implementation of __aeabi_atexit() since the new one seems to crash a static ICU String destructor.
I don't have the time to investigate why right now, so a revert is preferred. Damn...

Fix __aeabi_atexit to call __cxa_atexit properly. This function is defined by the C++ ABI for ARM document.

the issue is that the BSD implementation doesn't accept a call like:

  getaddrinfo(SERVER_NAME, "9999", NULL, &res);

because if will reject a numerical string in the second parameter if no hints are explicitely
provided. This technically doesn't violate POSIX but might make porting Linux software a bit
difficult. For more details see:

http://groups.google.com/group/android-ndk/browse_thread/thread/818ab9c53f24c87

also comment debugging printf() calls which shouldn't be there.

* changes:
  Add the domain search list for VPN connection.   The current solution is to read the net.dns.search property, and expand the list during the resolve initialization. In the future, we could implement search list per process.

Increase the limit of loaded shared libraries from 64 to 96 This change is required for OpenCORE 2.0
This is the same as Change 71 in master branch.

We're soon going to stop using TARGET_BUILD_TYPE==debug to debug
native modules.

Update: refine the code accordingly.

Update: remove unnecessary code.

Update: remove the unused variable.

  In new, include cstddef which declares std::size_t.

  Even if we don't want to have a bloated stl implementation, having empty
  files around is probably not very good either.
  Added a test to make sure the header file compiles on host and kila-eng.
  QA Impact: In system/extras/test/bionic/libstdc++ build the tests using:
  mm BIONIC_TESTS=1
  to build the host and target tests.
