target memory allocation can be implemented not to show
bogus error messages.
E.g. when trying a big allocation first and then a
smaller one if that fails.

Fixing one bug can easily uncover another .... in this case,
making sure that we properly invalidate some cached NOR state when
resuming arbitrary target code turned up an issue when the code
wasn't quite arbitrary (and we couldn't know that, but some parts
of OpenOCD assumed the cache would not be invalidated.
Specifically: some flash drivers (like CFI) update that state in loops
with downloaded algorithms, thus invalidating the state as it's probed.
+ Add a new target state flag, to record whether the target is
running downloaded algorithm code.
+ Use that flag to add a special case: "trust" downloaded algorithms
not to corrupt that cached state, bypassing cache invalidation.
Also update some of the documentation to stipulate that this flavor of
trustworthiness is now *required* ... not just a fortuitous acident.

Allow targets to run checks post reset. Used to check

Don't include <helper/jim.h> from target.h ... not everything
which touches targets needs to be able to talk to Jim. Plus,
most files include this header by another path.
Also, switch the affected files to use the classic sequence
for #included files: all <framework/headers.h> first, then
the "local_headers.h". This helps prevent growth of problematic
layering, by minimizing entanglement.

Most of these happened to be in the target.h file.
Some of those are associated with symbols that could be
removed at some point ... e.g. NVP_ASSERT/true and its
sibling NVP_DEASSERT/false.

Provide and use debug_reason_name() instead of expecting targets
to call Jim_Nvp_value2name_simple(). Less dependency on Jim, and
the code becomes more clear too.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "types.h"
the following form should be used.
#include <helper/types.h>
The exception is from .c files in the same directory.

This defines a "reset-assert" event and a supporting utility
routine, and documents both how targets should implement it
and how config scripts should use it. Core-specific updates
are needed to make this work.

Several of the sites now using target_type_name() really
ought to be using an instance-specific name. Create a
function called target_name(), accessing the instance's
own (command) name.
Use it in several places that really should be displaying
instance-specific names. Also in several places which
were already doing so, but which had no wrapper to call.

There are two names that may matter on a per-target basis.
One is a per-instance name (for example, "at91sam7s.cpu").
The other is the name of its type (for example, "arm7tdmi"),
which is shared among multiple targets.
Currently target_get_name() returns the type name, which is
misleading and is rarely appropriate for target diagnostics.
Rename that as target_type_name().

The container_of macro is useful as a general solution. It belongs
in types.h, rather than target.h where it was introduced. Requires
the offsetof macro, which comes from <stddef.h> (moved as well).

Lots of files still include it, often through needless
duplicate inclusion of "log.h"; sigh.
This cleans up the inclusion graph a bunch, so there are
fewer inclusion paths, but it doesn't change much otherwise.

Most files in the tree seem to have ended up including this,
and *quite* needlessly ... only code implementing or using
downloadable algorithms actually needs these declarations.
So take it out of the header files which included it, and put
it in files which use it ... reduce needless interdependencies.
Also: "algorithm.h" doesn't need to include "types.h" again;
it already comes from a different header.

Previously this flag was stored in "target_type", so that for example
if there were two ARM7TDMI targets in a scan chain, both would claim
to have been examined although only the first one actually had its
examine() method called.
Move this state to where it should have been in the first place, and
hide a method that didn't need exposure ... the flag is write-once.
Provide some doxygen. The examine() method is confusing, since it
isn't separating one-time setup from the after-each-reset stuff. And
the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug
state alone after reset ... probably more of an issue for trace setup
than for watchpoints and breakpoints.

Provide a cleaner way to handle single inheritance of targets
in C, using the same model Linux does: structs containing other
structs, un-nested via calls to a "container_of()" macro that
are packaged in typesafe inline functions.
Targets already use this containment idiom, but make it much
more complicated because they un-nest using embedded "void *"
pointers ... in chains of up to five per target, which is all
pure needless complication. (Example: arm92x core, arm9tdmi,
arm7_9, armv4_5 ... on top of the base "target" class.)
Applying this scheme consistently simplifies things, and gets
rid of many error-prone untyped pointers. It won't change any
part of the type model though -- it just simplifies things.
(And facilitates more cleanup later on.)
Rule of thumb: where there's an X->arch_info void* pointer,
access to that pointer can and should be removed. It may be
convenient to set up pointers to some of the embedded structs;
and shrink their current "*_common" names (annoyingly long).

Fixed bug: if virtual address for working memory was not specified
and MMU was enabled, then address 0 would be used.
Require working address to be specified for both MMU enabled
and disabled case.
For some completely inexplicable reason this fixes the regression
in svn 2646 for flash write in arm926ejs target. The logs showed
that MMU was disabled in the case below:
