41070dd15f bionic: Fix wrong prototype of system call getresuid/getresgid
In bionic/libc/SYSCALLS.TXT, the prototypes of system call
getresuid/getresgid are incorrect.

According to man page, they should be:
    int getresuid(uid_t *ruid, uid_t *euid, uid_t *suid);
    int getresgid(gid_t *rgid, gid_t *egid, gid_t *sgid);

5fbf2e0992 libc: Define new symbol visibility macros
This patch defines a few new macros that can be used to control the
visibility of symbols exported by the C library:

- ENTRY_PRIVATE() can be used in assembly sources to indicate
  that an assembler function should have "hidden" visibility, i.e.
  will never be exported by the C library's shared library.

  This is the equivalent of using __LIBC_HIDDEN__ for a C function,
  but ENTRY_PRIVATE() works like ENTRY(), and must be used with
  END() to tag the end of the function.

- __LIBC_ABI_PUBLIC__ can be used to tag a C functions as being
  part of the C library's public ABI. This is important for a
  few functions that must be exposed by the NDK to maintain
  binary compatibility.

  Once a symbol has been tagged with this macro, it shall
  *never* be removed from the library, even if it becomes
  directly unused due to implementation changes
  (e.g. __is_threaded).

- __LIBC_ABI_PRIVATE__ can be used for C functions that should
  always be exported by the C library because they are used by
  other libraries in the platform, but should not be exposed
  by the NDK. It is possible to remove such symbols from the
  implementation if all callers are also modified.

+ Add missing END() assembly macro for x86

70b1668a76 remove obsolete SuperH support
We don't have a toolchain anymore, we don't have working original
kernel headers, and nobody is maintaining this so there is really
no point in keeping this here. Details of the patch:

- removed code paths from Android.mk files related to the SuperH
  architecture ("sh")

- removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh

- simplified libc/SYSCALLS.TXT

- simplified the scripts in libc/tools/ and libc/kernel/tools

ec7e8cc9dd do not merge. Move property setting from libcutils to bionic.
Backport I110b653a58f3

All the other property stuff is already here.  Property setting was
only in libcutils previously to leverage a utility function / constant
or two.

Unfortunately in the process of fixing a race condition we would've
had to do break abstraction boundaries and put some libc-internal
details into libcutils so instead of that we'll just move this
into bionic.

Along with Iee1ca9b7, this now passes:

$ adb shell am instrument -w -e class android.os.SystemPropertiesTest \
  com.android.frameworks.coretests.systemproperties/android.test.InstrumentationTestRunner

fc2693110e libc: Update auto-gen scripts
Make the scripts use external/kernel-headers/original by default.

clean_header.py:  Document -k<path>, add -d<path>
find_headers.py:  Make kernel config files optional
update_all.py:    Allow setting the path to kernel headers on the command-line
update_all.py:    Better formatting of output on ttys
update_all.py:    Automatically perform "git add/rm" on affected files.
SYSCALLS.TXT:     Fix typo in __socketcall definition.
checksyscalls.py: Add support for superH architecture in the checks.
gensyscalls.py:   Automatically perform "git add/rm" on affected files.
cpp.py:           Fixed a bug that prevented certain type definitions to
                  be kept in the generated clean header (e.g.
                  struct ethtool_drvinfo in <linux/ethtool.h>)

All scripts will use the content of external/kernel-headers/original by default now.

The generated code removes all empty lines and trailing whitespace. This is useful
to ensure a unified output even if we change the parser again in the future.

The top-level disclaimer has been edited with update instructions to regenerate
the headers when needed.

Also, a warning is now inserted every 8th line in the final output:

/* WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS */

Changes under kernel/arch-arm and kernel/arch-x86 should correspond to whitespace
differences and additionnal struct definitions that were missed by the previous
parser implementation.

WARNING: If you run these script, do not submit the result to gerrit for now.
         It seems there are discrepancies between the content of original headers
         and those currently commited under bionic/libc/kernel/.

         (This problem is the main motivation to insert the warning repeatedly).

         Current list of issues:

           - Missing SuperH headers (i.e. external/kernel-headers/original/asm-sh)

95d751feac libc: Add ftruncate64 and improve 64-bit parameter syscall handling.
This patch improves the handling of 64-bit parameters in syscalls on ARM.
The ARM EABI mandates that 64-bit quantities be passed in even/odd register
pairs, which requires special treatment.

This allows us to simplify our implementations of pread() and pwrite()
and remove the C stubs for pread64() and pwrite64().

Also add ftruncate64() to <unistd.h>
