Add a struct to describe the branch trace configuration and use it for
enabling branch tracing.
The user will be able to set configuration fields for each tracing format
to be used for new threads.
The actual configuration that is active for a given thread will be shown
in the "info record" command.
At the moment, the configuration struct only contains a format field
that is set to the only available format.
The format is the only configuration option that can not be set via set
commands. It is given as argument to the "record btrace" command when
starting recording.

/* Printers for the debug target. Each prints an object of a given
|
||
type to a string that needn't be freed. Most printers are macros,
|
||
for brevity, but a few are static functions where more complicated
|
||
behavior is needed.
|
||
|
||
References to these printers are automatically generated by
|
||
make-target-delegates. See the generated file target-delegates.c.
|
||
|
||
In a couple cases, a special printing function is defined and then
|
||
used via the TARGET_DEBUG_PRINTER macro. See target.h.
|
||
|
||
A few methods still have some explicit targetdebug code in
|
||
target.c. In most cases this is because target delegation hasn't
|
||
been done for the method; but individual cases vary. For instance,
|
||
target_store_registers does some special register printing that is
|
||
more simply done there, and target_xfer_partial additionally
|
||
bypasses the debug target. */
