45328ea124 Add buffering support for flash drivers. 
Some devices can get a significant boost in performance by writing to
flash memories one page at a time.  Generic function to do this are
provided at the target layer and may be used by flash drivers.

e0a8ce5a88 STM32L0x target support. 
Target support for stm32l0's and stm32l1's including option bytes and
data EEPROM.  This module will superceed the previous stm32l1 driver.

o Program flash write and erase.
o Options modification and interpretive status.
o Stubs for program flash writes and erases.  Stubs are modestly
  faster than non-stub version.   The stm32l0 will not execute stubs
  when the MCU has crashed.  A monitor option may be used to force
  non-stub flash writes.
o Stubs generated from C++ code and converted to arrays of half-words.
o Writes to data EEPROM supoprted when loading segments.
o EEPROM data monitor command to write words.
o Stubs supported on stm32l1.

4d4813de87 Clean up includes everywhere. 
All source files include general.h first and before anything else.
This inlcludes platform.h and platform_support.h
No header file needs to include to include any of these, but should include
any others needed for it's own declarations.

e0fc21a2a7 adiv5_swdp: allow to connect to a sleeping target by pulling SRST 
This patch introduces a new command, "connect_srst [enable|disable]"
which allows to enable special mode in which SRST would be pulled low
before the SWD scan till attaching to a target.

Since on Cortex-Mx the SRST signal doesn't gate JTAG and SWD, it's
possible to connect to a target while holding reset, ask it to stop at
reset vector and only then deassert reset, thus allowing to attach to
the kind of firmware that goes immediately to sleep or disables
debugging by other means early on start.

Tested on an STM32VLDiscovery board with STM32F100 configured to go to
STOP mode and executing WFI in the very beginning of main().
