The patch improves flash erase for STR9x in case of a full bank erase.
Then the chip erase command is used instead which improves speed significantly.
Also I think it might help if e.g. STR912 enters some state where flash banks are locked, and a chip erase command is the key for unlocking the flash.
ocd_ prefix is used internally in OpenOCD as a kludge more
or less to deal with the two kinds of commands that OpenOCD
has.

if polling is off, then "reset run + halt" would fail
since halt incorrectly assumed the target was in the
reset state as it is the internal poll implementation
that moves the sw tracking of the target state out
of the reset state.
To reproduce:
> reset run; halt

This adds the guts of a transport framework with initialization,
which should work with current JTAG-only configurations (tested
with FT2232).
Each debug adapter can declare the transports it supports, and
exactly one transport is initialized. (with its commands) in
any given OpenOCD session.
* Define a new "struct transport with init hooks and a few
"transport" subcommands to support it:
"list" ... list the transports configured (just "jtag" for now)
"select" ... makes the debug session use that transport
"init" ... initializes the selected transport (internal)
* "interface_transports" ... declares transports the current interface
can support. (Some will do this from C code instead, when there are
no hardware versioning (or other) issues to prevent it.
Plus some FT2232 tweaks, including a few to streamline upcoming
support for an SWD transport (initially for Luminary adapters).
Eventually src/jtag should probably become src/transport, moving
jtag-specific stuff to transport/jtag.

When an interactive command fails, the Jim stack trace prints references to
the line in "command.c" where the interpreter was invoked. Since that
location has no relation to the actual command that failed, the information
serves only to add confusion.
By not adding the useless source info to Jim the noise can be reduced,
while still printing a useful trace for nested commands.
