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.

This adds a virtual flash bank driver that allows virtual banks to
be defined that refer to an existing flash bank.
For example the real address for bank0 on the pic32 is 0x1fc00000
but the user program will either be in kseg0 (0xbfc00000) or
kseg1 (0x9fc00000).
This also means that gdb will be aware of all the read only flash
addresses.

There are a million reasons why cached protection state might
be stale: power cycling of target, reset, code executing on
the target, etc.
The "flash protect_check" command is now gone. This is *always*
executed when running a "flash info".
As a bonus for more a more robust approach, lots of code could
be deleted.

Clean up the jtag/tcl.c file, which was one of the biggest and
messiest ones in that directory. Do it by splitting out all the
generic adapter commands to a separate "adapter.c" file (leaving
the "tcl.c" file holding only JTAG utilities).
Also rename the little-used "jtag interface" to "adapter_name", which
should have been at least re-categorized earlier (it's not jtag-only).

We'll need to be able to work with debug adapter interfaces (drivers)
even when they're not used for JTAG ... for example, while there are
multi-transport drivers which support JTAG *and* several other
transports (or just one more, like SWD) there are also adapters
with more limited goals (and no JTAG support at all).
Start decoupling the two concepts ("debug adapter driver", "jtag")
by having two command groups, which initialize separately.
This will help us support OpenOCD sessions using only non-JTAG
transports, in which JTAG commands should not be registered.
Update docs to mention that the JTAG, SVF, and XSVF commands
won't work without a JTAG transport.
Note that at least commands working with SRST are still inappropriately
coupled to JTAG ... inappropriate because (a) SRST is not part of the
JTAG standard, for all that many platforms (like ARM) expect it; and also
(b) because they're used with non-JTAG debug and programming interfaces,
too. They should perhaps become generic "interface" operations at some
point. (Similarly with the clock rate to be used by a given adapter.)

Talk more about "debug adapters" instead of only "dongles". Not all
adapters are discrete widgets; some are integrated onto boards. If
we only talk about "dongles" we rule out many valid setups, and help
confuse some users (who may be using Dongle-free environments).
Also start bringing out the point that JTAG isn't the only transport
protocol, even though OpenOCD historically presumes "all is JTAG".
(Not all debug adapters are JTAG adapters, or JTAG-only adapters.)
Plus a few minor fixes (spelling etc) in the vicinity of those changes,
and updates about FT2232H clocking issues (they can go faster than the
older chips, and can support adaptive clocking).

Stellaris chips have a procedure for restoring the chip to
what's effectively the "as-manufactured" state, with all the
non-volatile memory erased. That includes all flash memory,
plus things like the flash protection bits and various control
words which can for example disable debugger access. clearly,
this can be useful during development.
Luminary/TI provides an MS-Windows utility to perform this
procedure along with its Stellaris developer kits. Now OpenOCD
users will no longer need to use that MS-Windows utility.

Remove long-obsolete text about "erase_check" affecting "flash info" output.
Move parts of that text to "protect_check", where it's still relevant; and
update the "flash info" description to mention the issue.
(This is still awkward. It might be best to make "protect_check" mirror
"erase_check" by dumping what it finds, so "flash info" doesn't dump any
potentially-stale cache info.)

The "-f" is a shortcut for "-c" ... and providing any "-c" options
means the "openocd.cfg" file isn't implicitly used. Both the User's
Guide and the manual page were weak on these points, which has led
to some confusion.
Also update the manual page to include highlights of the search path
mechanism, including the facts that it exists and that "-s" adds to it.
Stop saying only the current directory is involved; the OpenOCD
script library is quite significant.
(Missing: complete manpage coverage of the search path, including a
FILES section listing all components and saying where the script
library is found.)

This addresses what would otherwise be something of a functional
regression. An earlier version of the interface had a dangerous
problem: it would silently erase data outside the range it was
told to erase. Fixing that bug turned up some folk who relied on
that unsafe behavior. (The classic problem with interface bugs!)
Now they can get that behavior again. If they really need it,
just specify "pad".

The "parport_port" commands generally don't *require* a port_number;
they're of the "apply any parameter, then print result" variety. Update

Some of those commands are intended to be write-once: parport_port,

Parport address 0xc8b8 is evidently mutant. Say so in the "parport.cfg"
