Default values for .first_bank_size_kb and .has_dual_banks fields

Basing on:
STM32L0x1 RM0377
STM32L0x2 RM0376
STM32L0x3 RM0367
STM32Lxxxx RM0038

correct values for memory layouts were selected:
id = 0x447 STM32L0xx (Cat.5) <- dual bank flash
for size 192 or 128 KBytes, single bank for 64 KBytes
id = 0x436 STM32L1xx (Cat.4 / Cat.3 - Medium + /
High Density) <- only one size of the bank,
default values are correct
id = 0x437 STM32L1xx (Cat.5 / Cat.6) <- always dual bank,
but size of the bank can be different

For that reason .part_info field in struct stm32lx_flash_bank
is a dynamic field with fields copied from stm32lx_parts[]
and overwriten to correct values
for specific chips and memory sizes.

Increasing the trace buffer size on the st-link itself gives openocd a greater
chance of avoiding trace data overflowing within the st-link between polls
when there is a large amount of data being sent over the trace port

The st-link appears to split the given buffer size in half
while one half is awaiting transfer over USB, the other half is being
filled by DMA transfer.  If you do not poll frequently enough, the DMA
transfer will overflow back to the start of its current buffer, resulting in
corrupted output

Buffer size of 4096 bytes is the maximum allowed by the st-link v2

This patch contains a major overhaul of the target run control,
mainly for the sake of satisfying gdbs ideas of how a target
should respond to various control requests for the debugger.

The changes allow gdb a slightly better control on how cores
are stepped: a core can be single-stepped while 
other cores remain halted or continue normal execution 
until the single-stepped core halts again.

Also, on any halting event (user command or breakpoint) the
system is brought into a stable state with all cores halted
before the halt is signaled to the debugger.

This patch also transitions the target code to make use of the
new CTI abstraction instead of accessing CTI registers directly.
