Fix serious bug in LPC2xxx/LPC17xx flash algorithm.
Flash algorithm for LPC17xx/LPC2xxx was trying to "reuse" previously
allocated working area on next flashing which is not possible -
working areas are freed automatically on reset. This caused all but
first flashing attempts to fail. As there is no point in storing pointer
to working area, it was converted to local variable.
This patch adds ChibiOS/RT support. This patch requires at least
ChibiOS/RT development version starting from SVN revision 4734.
Note, that the Thread structures depend not only on the target
but also on the ChibiOS configuration at build time.
To correct this ChibiOS includes a new "memory signature" which
specifies the offsets.
Special thanks go to Peter Stuge and Spencer Oliver for their
continous input and feedback to this patch.
rtos: Don't crash on qSymbol GDB packet when no RTOS is configured
Commit 43902905bbc8fdc9d764f3843d697161d9b5fd92 fixed a bug but also
introduced a regression. The RTOS GDB packet handler is always called,
not only when an RTOS is actually configured, so it is important to
check if an RTOS has been configured or not before actually processing
the qSymbol packet.

rlink: Fix DTC command timeout
With the current timeout setting i = 10 in drtc_run_timeout()
I get "Error: too many retries waiting for DTC status" when
loading a program into the FLASH of an STM32F1.
By experimentation a value of i = 22 was found to be the minimum
on my system. Therefore the value has been increased to i = 50.

The erase time for the option byte page is not directly specified but is
assumed to be the same as the other pages (or mass erase) which is 20 to
40 ms. The current timeout value is 10 which means 10 ms plus the time to
poll the status flag that many times.
With faster interfaces or drivers (such as when using the ftdi driver
instead of the ft2232 driver) the adapter delay is not enough in some
cases, unless the jtag freq is reduced as a workaround. The result is a
"timed out waiting for flash" error when trying to write the options.
Increase the timeout to a minimum of 100 ms, which is in line with the
other erase timeouts. Also make defines of both the erase and the program
timeouts.

rtos: Rewrite rtos_try_next() for readability
The new code is almost functionally equivalent to the old.
The function now returns 0 instead of -1 if target->rtos has not yet
been allocated. All call sites only test for success, and in practise
that is also the only thing that matters; if the function successfully
iterated to the next RTOS or not.
Other than that the only difference is that the code is now readable.
Many thanks to Matthias Blaicher for the fix to the iteration error!
In FLASHD_ErasePages AT91C_EFC_FCMD_EPA is used to erase sectors.
According to the datasheet FARG[15:2] defines the page from which
the erase will start.This page must be modulo 4, 8, 16 or 32
according to the number of pages to erase. FARG[1:0] defines the
number of pages to be erased. Previously (firstpage << 2) was used
to conform to this, seems it should not be shifted... Changed it
to (firstPage) | erasePages.

SPI nor drivers refactor
Moved common SPI flash driver code (device table,
common commands) into flash/nor/spi.c and spi.h.
Updated flash/nor/stmsmi.c to reflect this refactor.
In at91sam3.c for Atmel SAM3 flash support, there are arithmetic errors in the functions sam3_page_read() and sam3_page_write().
Address locations are computed incorrectly due to an extra addition operation. This leads to memory locations being skipped during
flash writes and reads.
Smaller programs are written successfully into flash, with memory gaps, while larger programs of legitimate size fail because the
skipped memory is not utilized and therefore unavailable.
The changes address this condition, and have been tested with an Atmel SAM3X-EK evaluation board.
