  1. bionic: Fix aliasing violations 

    This makes bionic compile with compilers enforcing
strict adherence to aliasing rules (e.g. gcc 4.6+
with -Wstrict-aliasing=2 -Werror=strict-aliasing).

  2. libm: Add a proper sincos() implementation 

    Add a proper sincos() implementation that unifies the common
calculations for sin and cos instead of running them twice.

This should cause a speedup even in code not using that
(fairly uncommon) function because gcc can optimize separate
sin() and cos() calls into sincos() calls.

  6. TLS: Call kernel helper in additional situations 

    ARMv6 has HW TLS support, and thus we should be using it rather
than hacking the Linux Kernel to use the software mechanism.
Unfortunately, ARMv6 targets without Thumb2 do not support the
necessary TLS instructions in Thumb Mode. Converting the tls libc
routines to ARM Mode will require an additional branch to switch
modes. Therefore, let's simply use the Kernel's Helper Routine
which already operates in ARM Mode. This changed behavior only
applies if the HAVE_ARM_TLS_REGISTER option is defined.
Otherwise, the existing paradigm is used.

  12. headers: Unbreak some ARM syscalls 

    Restore the outside-kernel exclusion for some syscalls that was
removed by change I959b64280e184655ef8c713aa79f9e23cb1f7df4,
since these syscalls are used elsewhere.
