-												auto-generate most target debug methods

The target debug methods are inconsistently maintained.  Most to_*
methods have some kind of targetdebug awareness, but not all of them
do.  The ones that do vary in the quantity and quality of output they
generate.

This patch changes most of the target debug methods to be
automatically generated.  All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.

For example now you'd see:

    -> multi-thread->to_terminal_ours (...)
    -> multi-thread->to_is_async_p (...)
    <- multi-thread->to_is_async_p (0x1ebb580) = 1
    <- multi-thread->to_terminal_ours (0x1ebb580)
    -> multi-thread->to_thread_address_space (...)
    <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1

In this case you can see nested calls.  The "multi-thread" on the left
hand side is the topmost target's shortname.

There are some oddities with this patch.  I'm on the fence about it
all, I really just wrote it on a whim.

It's not simple to convert every possible method, since a few don't
participate in target delegation.

Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.

On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack.  The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier.  (That said there are some gotchas
lurking in this idea due to target stack introspection.)

Regtested on x86-64 Fedora 20.

-												btrace: add struct btrace_data

Add a structure to hold the branch trace data and an enum to describe
the format of that data.  So far, only BTS is supported.  Also added
a NONE format to indicate that no branch trace data is available.

This will make it easier to support different branch trace formats in
the future.

-												record btrace: add configuration struct

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.

-												auto-generate most target debug methods

The target debug methods are inconsistently maintained.  Most to_*
methods have some kind of targetdebug awareness, but not all of them
do.  The ones that do vary in the quantity and quality of output they
generate.

This patch changes most of the target debug methods to be
automatically generated.  All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.

For example now you'd see:

    -> multi-thread->to_terminal_ours (...)
    -> multi-thread->to_is_async_p (...)
    <- multi-thread->to_is_async_p (0x1ebb580) = 1
    <- multi-thread->to_terminal_ours (0x1ebb580)
    -> multi-thread->to_thread_address_space (...)
    <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1

In this case you can see nested calls.  The "multi-thread" on the left
hand side is the topmost target's shortname.

There are some oddities with this patch.  I'm on the fence about it
all, I really just wrote it on a whim.

It's not simple to convert every possible method, since a few don't
participate in target delegation.

Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.

On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack.  The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier.  (That said there are some gotchas
lurking in this idea due to target stack introspection.)

Regtested on x86-64 Fedora 20.
