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().

9c95f039cf Make code compatible with newlib-nano and use it for stlink 
With gcc-arm-none-eabi-4_7-2013q1-20130313 and -O2 I get
   text    data     bss     dec     hex filename
  45744     304    2376   48424    bd28 blackmagic

With -Os the results are even more impressive:
   text    data     bss     dec     hex filename
  37900     304    2376   40580    9e84 blackmagic

Since -Os might lower the debugging speed, do not enable it yet in the
absence of real measurements.

e8f9d52d2f gdb_if: Fix USB flow control. 
The introduction of the double buffering broke USB flow control, causing
loss of data when a new packet arrived with the previous still present in
the double buffer.

With this patch the endpoint is kept in NAK until the double buffer is empty.

04624af4e5 f4discovery: Adapt from the "native" file and add or change code where needed 
- stm32_mem.py has problems with erasing the big pages, but dfu-util works
- serial GDB remote server doesn't work. It neither works for the STM32F107,
  so maybe there is a problem with the usbd_f107_driver.
