Patch 2/4 of the effort to make TLS access async-signal-safe.
Add a signal-safe malloc replacement. 2013-12-18 Andrew Hunter <ahh@google.com> * sysdeps/generic/ldsodefs.h (__signal_safe_memalign): New prototype. (__signal_safe_malloc, __signal_safe_free): Likewise. (__signal_safe_realloc, __signal_safe_calloc): Likewise. * elf/dl-misc.c (__signal_safe_allocator_header): New struct. (__signal_safe_memalign, __signal_safe_malloc): New function. (__signal_safe_free, __signal_safe_realloc): Likewise. (__signal_safe_calloc): Likewise. * elf/dl-tls.c (allocate_dtv, _dl_clear_dtv): Call signal-safe functions. (_dl_deallocate_tls, _dl_update_slotinfo): Likewise.
