Do target_terminal_ours in query & friends instead of in all callers
Any time a caller calls query & friends / prompt_for_continue without
ensuring that gdb owns the terminal for input is a bug. So do that in
defaulted_query / prompt_for_continue directly instead.
An example of a case where we currently miss calling
target_terminal_ours is internal_error. Ever since defaulted_query
was made to use gdb_readline_callback, there's no way to answer the
internal error query if the internal error happens while the target is
has the terminal:
(gdb) c
Continuing.
.../src/gdb/linux-nat.c:1676: internal-error: linux_nat_resume: Assertion `dummy_counter < 10' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) _
Entering 'y' or 'n' does not work, GDB does not respond.

PR gdb/19828
* gnu-nat.c (inf_validate_task_sc): Don't call
target_terminal_ours / target_terminal_inferior around query.
* i386-tdep.c (i386_record_lea_modrm, i386_process_record): Don't
call target_terminal_ours / target_terminal_inferior around
yquery.
* linux-record.c (record_linux_system_call): Don't call
target_terminal_ours / target_terminal_inferior around yquery.
* nto-procfs.c (interrupt_query): Don't call target_terminal_ours
/ target_terminal_inferior around query.
* record-full.c (record_full_check_insn_num): Remove
'set_terminal' parameter. Don't call target_terminal_ours /
target_terminal_inferior around query.
(record_full_message, record_full_registers_change)
(record_full_xfer_partial): Adjust.
* remote.c (interrupt_query): Don't call target_terminal_ours /
target_terminal_inferior around query.
* utils.c (defaulted_query): Install cleanup to restore target
terminal. Put target_terminal_ours_for_output in effect while
defaulted producing, and target_terminal_ours in in effect while
handling input.
(prompt_for_continue): Install cleanup to restore target terminal.
Put target_terminal_ours in in effect while handling input.
