Fixed a number of bugs. * libblock/src/blkdev.c: Release the disk device on an error. * libblock/src/diskdevs.c: Set the block size to the media block size during initialisation of the disk device. * libblock/src/flashdisk.c, libblock/src/nvdisk.c, libblock/src/ramdisk.c: Updated the drivers to handle variable block sizes. * libfs/src/dosfs/fat.c, libfs/src/dosfs/fat.h: Release any buffers when an error occurs. The FAT buffer layer hangs onto a single buffer while mounted. This should be fixed. * sapi/inline/rtems/chain.inl: Added rtems_chain_set_off_chain, rtems_chain_is_node_off_chain, and rtems_chain_previous. * score/inline/rtems/score/chain.inl: Added _Chain_Set_off_chain, and _Chain_Is_node_off_chain. * libmisc/shell/main_ln.c, libmisc/shell/main_mknod.c, libmisc/shell/mknod-pack_dev.c, libmisc/shell/mknod-pack_dev.h: New shell commands. * libmisc/Makefile.am, libmisc/shell/shellconfig.h: Added ln and mknod commands. * libmisc/shell/hexdump-display.c: Fixed the reopen bug which showed up as a free with a bad pointer. * libmisc/shell/main_mount.c: List the user adding file system when listing the available file systems to mount. * libmisc/shell/utils-cp.c: Remove the fixed static copy buffer and use a large dynamic buffer. * score/inline/rtems/score/address.inl, score/src/coremsgsubmit.c, score/src/objectallocate.c, score/src/objectfree.c: Remove warnings.

* score/inline/rtems/score/thread.inl: Restore the BSP context -- do not save the current. This routine is also marked as not returning which saves the exit path code.

* score/inline/rtems/score/coremsg.inl: Fix compilation issue when notifications are not enabled.
2009-09-132009-09-13 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill1-16/+48

Since these are empty when priority-based message queues are disabled, this eliminates some of the conditionals.
