Document that getopt_long(3) can and will accept unique abbreviated long
option names.  This feature has been present since getopt_long(3) was first
released in NetBSD 1.5.  This is also standard GNU getopt_long(3) behavior.

in ints since there are multiple flavors.  The key point to get
across is that when storing as a type > byte it may be necessary
to do byte swapping depending on the machine's byte order.
Noticed by Tamas TEVESZ.

includes used a bit later (for instance on the vax)

codebase.  tested mostly by ckuethe and myself.  __dtoa() use now requires
a call to __freedtoa()

create special allocators for pginfo and pgfree structs instead of imalloc.
this keeps them separated from application memory.
for chunks, to prevent deterministic reuse, keep a small array
and swizzle the to be freed chunk with a random previously freed chunk.
this last bit only for chunks because keeping arbitrarily large regions
of pages around may cause out of memory issues (and pages are, to some
extent, returned in random order).
all changes enabled by default.
thanks to ben for pointing out these issues.
