Oops, fix the fix in rev.1.10. logb() and logbf() were broken on
denormals, and logb() remained broken after 1.10 because the fix for
logbf() was incompletely translated.
Convert to __FBSDID().

Fix bug:
Currently the mutex lock _tls_desc_lock is not released
when __set_thread_area() fails. That will leads to the deadlock
when __set_tls( ) is called later on.

Some platform libraries built for ICS do not work with master
because of some refactoring in frameworks/base.
Make sure that these libgcc symbols are always present in our libc

That is to fix the bug:
dlxxx functions can't be called recursively.
For example, if we use dlopen() to use open one library whose constructor
also calls dlopen() in order to open another library, then the thread is
dead-blocked.
By changing the dl_lock from a non-recursive lock to a recursive lock, we can
prevent the thread from dead-blocked by recursive dlxxx calls in the same
thread context.

Prepend a 0 to match the new sequence-number style, though this module
doesn't really need/use it.

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

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

The flag to avoid calling ELF constructors recursively (in the case
of recursive .so dependencies) was being set after the dangerous
recursive constructor call had already been made.
This fixes the libc's debug malloc implementation.

This optimization improves the performance of recursive locks
drastically. When running the thread_stress program on a Xoom,
the total time to perform all operations goes from 1500 ms to
500 ms on average after this change is pushed to the device.

Write a message to the log file if the signal handler is not able
to connect to debuggerd. This is especially handy if the failure
was caused by running out of file descriptors, since there's some
chance that the lack of fds relates to the crash.
Sample:
F libc : Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1)
F libc : Unable to open connection to debuggerd: Too many open files
