aeaca988c3 target: Use new target_addr type consistently in external interface. 
Flash routines still use uint32_t internally.

c9d3cf71dd gdb_main.c: fix buffer overflow on large reads 
When gdb issues a `m xx,200` command, the probe should respond with a
packet of size 2*0x200=1024 which is the size of the packet buffer.

However, the `hexify()` procedures writes 1025 bytes in the buffer.

During my tests, it caused the probe to hang when issuing a `dump`
command. Presumably by overwritting the `cur_target` variable.

ee3af96a73 Consolidate target_mem_read* and target_mem_write* methods. 
There are now only mem_read and mem_write, that must
handle all alignments.  These methods return void, errors must be
checked with target_check_error.

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.

5020d1f05d Move semihosting support to cortexm.c.

aca421d0bb Basic semihosting support 
Implement bare minimum necessary to support console IO.

This works with standard newlib builds and is based on the reference
documentation:
http://infocenter.arm.com/help/topic/com.arm.doc.dui0471c/CHDJHHDI.html

Tested using gcc-arm-none-eabi-4_7-2013q1-20130313 for both
stm32f1-based BMP and stm32f0 target.

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.

ffda30f393 Add support for a more comprehensive target description, including the additional v7m registers. 
This doesn't work with vanilla gdb, as for reasons unknown said vanilla gdb doesn't support XML target descriptions queried from the remote.

Add code to the fault unwinder to deal with the stack alignment fixup and FP registers.  Avoid saving/restoring registers that don't get trashed.

adabaa7592 Halt and detach target if host releases DTR. 
Port reads 0x04 (EOF) when DTR is released.  GDB loop detaches from
target if EOF is read.
