80f30d4de0 Since we're returned the sign of a floating-point number by __dtoa(), 
use that to decide whether to include a minus sign in the result.
Fixes printing -0.0, and thus PR lib/3137.

4c99916337 va_{start,end} audit: 
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Improved by comments from enami and christos -- thanks!

Heimdal/krb4/KAME changes already fed back, rest to follow.

Inspired by, but not not based on, OpenBSD.

fa11ebb133 apparently ansi c only required fread(3) to return 0 if size or nmembs == 0. 
however, susv2 adds the same to fwrite(3), so add the explicit check.
document this for both fread & fwrite. move diagassert for buf!=NULL to after
the (size * nmembs) == 0 check.

this has the helpful side effect of preventing the _DIAGASSERT()ion in
fwrite() being triggered by lots of 3rdparty code that calls fwrite() with
buf=NULL count=0

681b2f48bc remove(3) doesn't remove dangling links due to stat() returning an

a25ce426d4 Remove the flag test when seeing if _double is zero or not. We 
are only testing for the cvt problem, not for alternate forms.
This change makes %#e and %e both correctly print 0.  It is just
a question of is it the proper number of zeros or not?
