Most of the QIODevice functions already have a locally cached
"sequential" flag. Make the rest of them follow this strategy.
This eliminates the need to use private caching members.

These hooks only worked reliably with LD_PRELOAD on Linux/GCC, on other
platforms they depended on what exactly the compiler optimizer is doing
as well as some nasty assembler rewriting to actually access them. The
new system uses a simple array of function pointers that can be set to
custom hooks by tools that need this (based on ideas from Andre Poenitz).
This also covers qt_startup_hook (similar problem), and the Qt version
number that Andre had asked for.
