Add DeepBind option to QLibrary
Adds an option to request the RTLD_DEEPBIND flag to dlopen. On Linux
this can be used to force a library to resolve global symbols locally
instead of using the similarly named symbols already loaded.
This makes it possible to load and use plugins linked against Qt 4
without crashing.
[ChangeLog][QtCore][QLibrary] Added DeepBindHint which maps to RTLD_DEEPBIND
on Linux making it possible to load libraries with external symbols that
clash with already loaded ones, such as plugins linked to Qt4.
