the wrong index of argv. argv[0] is the command itself,
argv[1] the the transport to select.

LOG_DEBUG() arguments are only evaluated when DEBUG logging
is enabled, do not use arguments that have side effects
like foo++.

Do not propagate error number to user. This is for internal
programming purposes only. Error messages to the user is
reported as text via LOG_ERROR().

Make it scriptable, so code can be conditionalized based on
what transport is in use for the session.

* Bugfix and simplify legacy jtag-only defaulting
* Make "dummy" declare its jtag-only nature
* likewise update ft2232
* warn if selection is _required_ (multi-transport adapters),
fixes the "only ft2232 works" bug for at least dummy, with
other drivers going the "legacy" path (submit patches).

String compare against addresses in range 0 or so due
to not checking if there was an active session first.

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.
