616a494ec1 Update endian.h from bionic.
This consolidates the guts of the three endian.h files (endian.h,
sys/endian.h, and machine/endian.h) into just sys/endian.h, and turns
the others into headers that forward to it.

This also consolidates all the architecture specific machine/endian.h
files into a single generic header.

Finally, this is also the update version of sys/endian.h, which just
forwards to compiler builtins rather than implementing it ourselves.

a5c12d1936 Update libm_hard.a
1) Add ldexp.  ldexp used to co-exist in both libc.so and libm.so until
   the removal from libm.so in ICS.  Unfortunately the sole copy of libm_hard.a
   in NDK was compiled from JB source and miss ldexp.  Code compiled with
   hard-float using ldexp may use libc.so which follows soft-float and misbehave
2) Turns out the following (all in fpclassify.o) also exists in recent libc.so
   too.  Add them in libm_hard.a as well:

    __fpclassifyd
    __fpclassifyf
    __fpclassifyl

556182feb4 Fix SEGV when unwinding stack pasts __libc_init
Changed "jump __libc_init" to "call __libc_init" otherwise stack unwinding
past __libc_init may get wrong return address and crash the program or do
wield things.  With "call", return address is pushed on stack and unwinding
stops correctly at _start.  Note that __libc_init never returns, so this
fix wonʼt affect normal program execution.  But just in case it "does"
return, jump to address 0 and halt.

5e7c4e6a57 ndk: Remove prebuilt C runtime objects. Add sources instead.
This patch removes all prebuilt C runtime object files from
the ndk/platforms/ directory. We replace them with equivalent
assembly sources lifted from the following directories:

  bionic/libc/private/      (for __dso_handle.S and __dso_handle_so.S)
  bionic/libc/arch-$ARCH/   (for all others)

Note: This requires that your NDK's gen-platforms.sh script be
      capable of rebuilding the object files from sources.
      See https://android-review.googlesource.com/36822

The goal here is to make it much easier to update these files,
and track their changes relative to the content of bionic/lib.
For example to fix the following issues in the future:

6dd4b91b32 Make sure __u64 is defined even for strict ansi or -std=c99
The x86 asm headers define __u64 regardless of __STRICT_ANSI__.
The linux/videodev2.h header requires __u64 to be defined, thus
this fixes compiling with -std=c99 when including the
linux/videodev2.h header.

In glibc, the asm/types.h header defines __u64 regardless of
__STRICT_ANSI__.

This commit copies the updated header from bionic into the ndk
platform headers.

e872f4e101 ndk: Remove obsolete platform files
Remove the prebuilt system shared libraries and unified symbol files
from development/ndk. We don't need them anymore:

  - the unified symbol files are replaced by separate functions/variables
    symbol list, which were added in a previous commit, i.e.:

	libc.so.txt  --> libc.so.functions.txt
	                 libc.so.variables.txt

 - the shared libraries are now generated on the fly by the NDK
   gen-platforms.sh script, from the functions/variables symbol lists.

Note that we need to keep the static libraries and runtime objects,
they are required to build the cross-toolchains and target binaries.

02053eb7a1 ndk: separate functions and variables symbol lists
This change introduces separate symbol lists for functions
and variables of each NDK system shared library.

Note that we don't remove the unified symbol files yet. This
will be done later when we complete other changes under ndk/,
namely the ability to generate platforms trees containing shell
libraries generated directly from them.

These files were generated using the following:

  cd development/ndk
  for DIR in platforms/*/*/lib; do
    for ARCH in arm x86; do
      $NDK/build/tools/gen-system-symbols $DIR $DIR/../symbols
    done
  done

This means that the symbol lists were generated by parsing the
existing prebuilt shared libraries under platforms/ and extracting
their function and variable names.

This is in preparation of another toolchain patch that will require
these files for all platform versions (for now, they are only defined
starting from android-9).

Note that these files are just copies of the existing ones, named
crtbegin_dynamic.o and crtend_android.o respectively.

The NDK build script will automatically use the new files if it finds
them, so shouldn't need to be updated.

This change removes the declaration of functions that are not

and macros, remove C++ comments, etc)

NOTE: This also contains careful separation of API-level-specific headers.
      For example, platforms/android-5/include/pthread.h contains new function
      declarations that are not available when using platforms/android-3/include/pthread.h

NOTE: The NDK's build-platforms.sh script has been updated to understand the new
      layout. This change in develeopment/ndk does not change the layout of
      platform files under $NDK/platforms after build-platforms.sh is called.

74ff6746d1 Remove C++ headers from the platform directories.
We now rely instead on the content of $NDK/sources/cxx-stl/system/include
that is automatically used if a module has C++ sources.

c817c5210e Copy platforms and samples from ndk/ source tree.
The idea is to allow developing the NDK in the open, while
having the platforms and samples under a private branch until
the corresponding release are open-sourced.
