This patch creates inferior when GDB opens a ctf trace data, to be
consistent with tfile target. A test case is added to test for
live target, tfile and ctf target.
gdb:
2014-02-05 Yao Qi <yao@codesourcery.com>
* ctf.c: Include "inferior.h" and "gdbthread.h".
(CTF_PID): A new macro.
(ctf_open): Call inferior_appeared and add_thread_silent.
(ctf_close): Call exit_inferior_silent and set inferior_ptid.
(ctf_thread_alive): New function.
(init_ctf_ops): Install ctf_thread_alive to to_thread_alive.

* gdb.trace/report.exp (use_collected_data): Test the output
of "info threads" and "info inferiors".
Confirmed that cross building a mingw gdb still works, and also made
sure it was gnulib's sys/stat.h that was defining the values, by
hacking the header with #errors where the macros are defined.

* ctf.c (ctf_start): Use S_IRGRP, S_IXGRP, S_IXOTH
unconditionally.
This patch is purely mechanical. It removes gdb_stat.h and changes
the code to use sys/stat.h.

* ctf.c (ctf_traceframe_info): Push trace state variables
present in the trace data into the traceframe info object.

* tracepoint.c (build_traceframe_info_xml): Output trace state
variables present in the trace buffer.
* ctf.c (ctf_fetch_registers): Change the type of 'regs' from
'char *' to 'gdb_byte *'. Cast the return value of
'bt_ctf_get_char_array' to 'gdb_byte *'.
ctf_save_write's second parameter is gdb_byte *, and all these
arguments are 'char *'. Since this function is ultimately just
writing host bytes to a local file with fwrite, an alternative would
be to change ctf_save_write to take a 'void *' instead of 'gdb_byte
*', thus removing the need for any cast (we have more calls with casts
than without).

2013-04-19 Pedro Alves <palves@redhat.com>

gdb/testsuite/
* gdb.base/completion.exp: Test completion of command
'target ctf' if target ctf is supported.
