Move the traceframe_available_memory code from memory_xfer_partial_1 down to the targets
As a follow-up to [PATCH 7/8] Adjust read_value_memory to use to_xfer_partial https://sourceware.org/ml/gdb-patches/2014-02/msg00384.html this patch moves traceframe_available_memory down to the target side. After this patch, the gdb core code is cleaner, and code on handling unavailable memory is moved to remote/tfile/ctf targets. In details, this patch moves traceframe_available_memory code from memory_xfer_partial_1 to remote target only, so remote target still uses traceframe_info mechanism to check unavailable memory, and use remote_ops to read them from read-only sections. We don't use traceframe_info mechanism for tfile and ctf target, because it is fast to iterate all traceframes from trace file, so the summary information got from traceframe_info is not necessary. This patch also moves two functions to remote.c from target.c, because they are only used in remote.c. I'll clean them up in another patch. gdb: 2014-03-22 Yao Qi <yao@codesourcery.com> * ctf.c (ctf_xfer_partial): Check the return value of exec_read_partial_read_only, if it is not TARGET_XFER_OK, return TARGET_XFER_UNAVAILABLE. * tracefile-tfile.c (tfile_xfer_partial): Likewise. * target.c (target_read_live_memory): Move it to remote.c. (memory_xfer_live_readonly_partial): Likewise. (memory_xfer_partial_1): Move some code to remote_read_bytes. * remote.c (target_read_live_memory): Moved from target.c. (memory_xfer_live_readonly_partial): Likewise. (remote_read_bytes): New, factored out from memory_xfer_partial_1.
