e30d92806f Increase the number of spinlocks, since libc's malloc implementation is 
about to significantly increase the number of spinlocks used.

3668a2e494 In preparation for a new malloc implementation: 
* Add posix_memalign().

  * Move calloc() from calloc.c to malloc.c.  Add a calloc() implementation in
    rtld-elf in order to make the loader happy (even though calloc() isn't
    used in rtld-elf).

  * Add _malloc_prefork() and _malloc_postfork(), and use them instead of
    directly manipulating __malloc_lock.

d6c88c0f27 Refine thread suspension code, now thread suspension is a blockable 
operation, the caller is blocked util target threads are really
suspended, also avoid suspending a thread when it is holding a
critical lock.
Fix a bug in _thr_ref_delete which tests a never set flag.

3e60ee73cb Follow the mistake in libpthread, the first version name in libpthread 
is LIBTHREAD_1_0, but really it should be LIBPTHREAD_1_0.
Fix it so libmap.conf works again (it was broken by recent versioning
code in rtld_elf).
