Use new to_xfer_partial interface in ctf and tfile target
This patch adjust both ctf and tfile target implementation of to_xfer_partial,
to return TARGET_XFER_E_UNAVAILABLE and set *XFERED_LEN if data is
unavailable. Note that some code on xfer in exec.c can be shared, but
we can do it in a separate pass later.
gdb:
2014-02-23 Yao Qi <yao@codesourcery.com>
* exec.c (section_table_read_available_memory): New function.
* exec.h (section_table_read_available_memory): Declare.
* ctf.c (ctf_xfer_partial): Call
section_table_read_available_memory.
* tracefile-tfile.c (tfile_xfer_partial): Likewise.
