bd6a7799c4 Optimize realloc() to reallocate in place if the old and new sizes are 
close enough to each other that reallocation would allocate a new region
of the same size.  This improves the performance of repeated incremental
reallocations by up to three orders of magnitude. [1]

Fix arena_new() to properly constrain run size if a small chunk size was
specified during runtime configuration.

2d07e432d4 Modify allocation policy, in order to avoid excessive fragmentation for 
allocation patterns that involve a relatively even mixture of many
different size classes.

Reduce the chunk size from 16 MB to 2 MB.  Since chunks are now carved up
using an address-ordered first best fit policy, VM map fragmentation is
much less likely, which makes smaller chunks not as much of a risk.  This
reduces the virtual memory size of most applications.

Remove redzones, since program buffer overruns are no longer as likely to
corrupt malloc data structures.

Remove the C MALLOC_OPTIONS flag, and add H and S.

e62165c8b0 Add compatibility symbol maps. libpthread (.so.1 and .so.2) 
used LIBTHREAD_1_0 as its version definition, but now needs
to define its symbols in the same namespace used by libc.
The compatibility hooks allows you to use libraries and
binaries built and linked to libpthread before libc was
built with symbol versioning.  The shims can be removed if
libpthread is given a version bump.

6348ace8d1 Use a thread pool to process notification if sigev_notify_attributes 
is default and caller does not require dedicated thread. timer needs
a dedicated thread to maintain overrun count correctly in notification
context. mqueue and aio can use thread pool to do notification
concurrently, the thread pool has lifecycle control, some threads will
exit if they have idled for a while.
