e2617290fc FORTIFY_SOURCE: emphasize prevention in error messages. 
FORTIFY_SOURCE prevents buffer overflows from occurring.
However, the error message often implies that we only
detect it, not prevent it.

Bring more clarity to the error messages by emphasizing
prevention over detection.

Make sure the buffer we're dealing with has enough room.
Might as well check for memory issues while we're here,
even though I don't imagine they'll happen in practice.

5f6cfce4f6 Add simple implementation _Unwind_GetIP() for clang compiles. 
Clang (prior to 3.4) does not actually provide a declaration (or definition)
of _Unwind_GetIP() for ARM. We can work around this by writing our own
basic implementation using the available primitive operations.

afcc0cccda Add mmap64() 
This adds mmap64() to bionic so that it is possible to have
large offset passed to kernel. However, the syscall mechanism
only passes 32-bit number to kernel. So effectively, the
largest offset that can be passed is about 43 bits (since
offset is signed, and the number passed to kernel is number
of pages (page size == 4K => 12 bits)).

9ae59c02ca Declare __page_shift and __page_size with C linkage. 
__page_shift and __page_size were accidentally declared in unistd.h with
C linkage - their implementation needs to use the same linkage.

Going forward, though, let's stop the inlining madness and let's kill
the non-standard __getpageshift(). This patch takes getpagesize(3) out
of line and removes __getpageshift but fixes __page_shift and __page_size
for backwards binary compatibility.

edad1e1558 Fix mismatch between declaration and forward declaration 
KernelArgumentBlock is defined as a class in KernelArgumentBlock.h, but
forward declarations refer to it as a struct.

While this is essentially the same, the mismatch causes a compiler
warning in clang (and may cause warnings in future versions of gcc) in
code that is supposed to be compiled with -Werror.
