Clean up DSBT support
The existing DSBT support relies on the kernel to provide DSBT info as part of the load maps passed to user space. The problem with this approach is that the DSBT info is in the dynamic section, so the kernel must access a userspace mapping of the dynamic section (or separately read a copy for the kernel) in order to retrieve the information needed by userspace. This patch reworks the DSBT support to remove the reliance on DSBT info coming from the kernel. Instead, ldso reads the info itself from the dynamic section. One other benefit of this is that it allows the existing kernel FDPIC loader to also load DSBT binaries.
