Start handling the (second) SRST stage of reset better:
make sure that when there are two or more targets, their various pre/post event reports are correctly ordered. Previously, only the first target always saw its "pre" method before SRST was asserted or deasserted. git-svn-id: svn://svn.berlios.de/openocd/trunk@2753 b42882b7-edfa-0310-969c-e2dbd0fdcd60
