6b2c15da6a Add malloc_usable_size(3). 
Discussed with:		arch@

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.

ae82896268 Consistently mark std(in|out|err) with .Dv, because that's how they 
are marked up in stdio(3), and because they are defined expressions
of type "FILE *".

f2572d955f Clarify the bit about realloc() and its `ptr' argument a bit. 
Hopefully, now it is more clear that the memory referenced by the
ptr argument of realloc(ptr,size) is freed and only the return value
of realloc() points to a valid memory area upon successful completion.

a9bef12a45 Markup nits: use diagnostic type lists for error and warning messages. 
Backout previous revision.  We should not expand plain text xrefs if
they appear in the literal text, e.g. in the error or warning message
of the library function.  (Submitted by: bde)

Moved "out of memory" from warning to errors section.

798c1fd885 Make it possible to override the function which writes messages to

Rename malloc_options to have a leading underscore, I belive I have been
told that is more correct namespace wise.
