Summer time in Cuba has been delayed 3 weeks (now starts April 1 rather
than March 11). Since March 11 (the old start date, as listed in 2012a)
is just a little over a week away, this change is urgent.

Falkland Islands onto permanent summer time (we're assuming for the
foreseeable future, though 2012 is all we're fairly certain of.)
Armenia has abolished Summer Time.
Tokelau jumped the International Date Line back last December
(just the same as their near neighbour, Samoa).
America/Creston is a new zone for a small area of British Columbia

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.

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 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 is the change for the generated arch-arm/asm/types.h
header, as produced by the update_all.py script (without all
the other unrelated changes that the script produces).
FWIW, the same issue also is present in
arch-sh/asm/types.h, but there are no source headers for
arch-sh in external/kernel-headers (and regenerating the
headers simply removes that file).

Issue:
The kernel will pad the entry->d_reclen in a getdents64 call to a
long-word boundary. For very long records, this could exceed the
size of a struct dirent. The mismatch in the size was causing error
paranoid checking code in bionic to fail... thus causing an early
"end" when reading the dirent structures from the kernel buffer.
Test:
ls
mkdir abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstu

When forking of a new process in bionic, it is critical that it
does not allocate any memory according to the comment in
java_lang_ProcessManager.c:
"Note: We cannot malloc() or free() after this point!
A no-longer-running thread may be holding on to the heap lock, and
an attempt to malloc() or free() would result in deadlock."
However, as fork is using standard lib calls when tracing it a bit,
they might allocate memory, and thus causing the deadlock.
This is a rewrite so that the function cpuacct_add, that fork calls,
will use system calls instead of standard lib calls.

(1) in pthread_create:
If the one signal is received before esp is subtracted by 16 and
__thread_entry( ) is called, the stack will be cleared by kernel
when it tries to contruct the signal stack frame. That will cause
that __thread_entry will get a wrong tls pointer from the stack
which leads to the segment fault when trying to access tls content.
(2) in pthread_exit
After pthread_exit called system call unmap(), its stack will be
freed. If one signal is received at that time, there is no stack
available for it.
Fixed by subtracting the child's esp by 16 before the clone system
call and by blocking signal handling before pthread_exit is started.

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.
