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.

499168546f Optimize arena_bin_pop() to reduce the number of separator operations. 
Remove the block of code that tries to use delayed regions in LIFO order,
since from a policy perspective, it conflicts with LRU caching of newly
coalesced regions in arena_undelay().  There are numerous policy
alternatives, and it isn't readily obvious which (if any) is superior;
this change at least has the virtue of being consistent with policy.

6dbacee284 Make the %V{is} extension handle a NULL pointer like %s does: output "(null)" 
Add %M{essage} extension which prints an errno value as the
corresponding string if possible or numerically otherwise.

It is not currently possible to do the syslog(3) like %m extension
because errno would need to get capatured on entry to the first
function in the printf family, so %M requires you to supply errno
as an argument.

Add %Q{uote} extension which will print a string in double quotes with
appropriate back-slash escapes (only) if necessary.
