the unlocking procedure erases the flash mem (even if it wasn't locked), so it should be marked as erased after unlocking.

Don't call a variable num_pages if it holds the flash size. Also rearrange
flash size to num_pages calculation to avoid divide-by-zero if there will
be a device with < 1024 byte pages someday.

Before this commit, openocd used to segfault when probing flash
of an at91sam7x512 (which contains 2 banks of flash). This was due
to the way it systematically insert a new flash bank without setting
its name.
Then, when get_flash_bank_by_name_noprobe() is called, it is doing
a strcmp() on the non-initialized bank->name.
This commit prevents allocation of second probed bank if it is already
allocated (for example, if it is set in a target config file). If a
new bank really needs to be allocated, it ensures that a default name
is set.

Let the target algorithm be running in the background and buffer data
continuously through a FIFO. This reduces or removes the effect of latency
because only a very small number of queue executions needs to be done per
buffer fill. Previously, the many repeated target state changes, register
accesses (really inefficient) and algorithm uploads caused the flash
programming to be latency bound in many cases. Now it should scale better
with increased throughput.

Access the different flash banks' registers using a bank specific register
base and a register specific offset. This is equivalent but feels more
natural.
Some accesses were discovered that maybe should not be hard coded to bank0
registers. Add a note about that.

crc check was always performed on newly flashed data, now it is optional
flash mem can be locked by writing a specific word to a specific address in flash.
to verify flash, target must be halted, and this will (when the new halt sequence is implemented) require reseting the chip. if the target is reset after writing the lock words, then it will lock, hence the CRC will fail because it is not possible to read stuff from the target.
also added a function that resets the jtag state machine.
this is not used yet, but will be soon.
it is implemented to allow strict control over JTAG state machine, necessary to implement to halt and unlocking sequences.
