Pull patch from -current: Fix by millert@ Previously, ld.so would use a single page for mapping the hints file and then, if that was not big enough, map the rest of it contiguously. However, there is no guarantee that the address space after the first mmap has not already been used by something else. Instead, just fstat the file and map up to st_size. Also reorganized the code a tad and added some sanity checks for st_size. Problem tracked down by dhartmei@ and mickey@; drahn@ OK. Ok deraadt@

Upon futher contemplation, the notion of unmaphints is just wrong. First the maphints code is not cleaning up after itself, by leaving a file descriptor open and trying to clean up after the dynamic linker is done loading by removing data needed during dlopen() is nonsense. the _dl_unmaphints() function and it's references have been removed. _dl_maphints() now cleans up it's file descriptor before returning. static data used later during dlopen() is left intact.

The unmaphints routine should not destroy the hint mapping. Otherwise shared modules which depend on libraries cannot find them because the list of trusted directories has been lost. However we need to be careful that the unmapping of the hints frees the file descriptor, but will not free it multiple times.

Updated version of ld.so, contains additional functionality and fixes/ design changes required by egcs. added support for ldconfig/ld.so.hints changes to low level relocation code, required by egcs pic code generation that moved global variable loads to before the self relocation was performed. Only powerpc supported, mips code not updated. Code cleaned up somewhat reasonably. This code needs to be reviewed closely for significant problems such as correctness and security.
