jGetLoadedDynamicLibrariesInfos. This packet is similar to qXfer:libraries:read except that lldb supplies the number of solibs that should be reported about, and the start address for the list of them. At the initial process launch we'll read the full list of solibs linked by the process -- at this point we could be using qXfer:libraries:read -- but on subsequence solib-loaded notifications, we'll be fetching a smaller number of solibs, often only one or two. A typical Mac/iOS GUI app may have a couple hundred different solibs loaded - doing all of the loads via memory reads takes a couple of megabytes of traffic between lldb and debugserver. Having debugserver summarize the load addresses of all the solibs and sending it in JSON requires a couple of hundred kilobytes of traffic. It's a significant performance improvement when communicating over a slower channel. This patch leaves all of the logic for loading the libraries in DynamicLoaderMacOSXDYLD -- it only call over ot ProcesGDBRemote to get the JSON result. If the jGetLoadedDynamicLibrariesInfos packet is not implemented, the normal technique of using memory read packets to get all of the details from the target will be used. <rdar://problem/21007465> llvm-svn: 241964
