* 2007-03-18 Martin Hunt <hunt@redhat.com>hunt2007-03-181-6/+5
| | | | | * stack.c, string.c, sym.c, transport/symbols.c: Fix some signed vs unsigned comparison warnings.

| | | | | | | | | | | | | | | | * transport_msgs.h: ifdef old messages as such. Add support for new transport. * relayfs.c: Simplify and add new interface to look like utt. * utt.[ch]: New files. Similar to the proposed utt interface. These setup and teardown relayfs on debugfs. * control.c: New file. Implements a simple control channel. A small subset of procfs.c. * procfs.c: This is now only used for old kernels lacking newer relayfs. Change STP_RELAYFS to STP_BULKMODE. Use new messages from transport_msgs.h. Don't support RELAYFS_CHANNEL_VERSION >= 4. CHanges all control channel functions to new names. Use pids instead of module names in /proc names.
