VG_(debugLog_vprintf). Remove function VG_(percentify) and fix up its call sites (part of fixing BZ #337869. Allow the width in a format specification to be '*', i.e. the width is given as an additional function argument. The limitations for printing floating point numbers are: (1) %f is the only supported format. Width and precision can be specified. (2) Funny numbers (NaN and such) are not supported. (3) Floating point numbers need to be benign in the sense that their integral part fits into an ULong. This is good enough for our purposes. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@14806

The extensions are:

%pS : print a string (like %s) but escaping chars for XML safety.
|
|
%ps : with --xml=no, synonym for %s, with --xml=yes, synonym of %pS.

as for the classical printf, %p requires a pointer, which must also

be provided for the %ps and %pS extensions. The s/S following %p
