* Fixup #318 serial print in stlink probe with trailing zeros
* Refactor stlink-usb.h with some doxygen-style comments
* Refactor some pieces of stlink_open_usb
Add some better sanity checking when using libusb_open and cleanup accordingly.
Fixes hang (debian 8, amd64, libusb 1.0.19):
libusb: warning [add_to_flying_list] failed to arm first timerfd (errno 9)
libusb: warning [libusb_close] internal signalling write failed, closing anyway
* Fixup README to render HTML from Markdown
* Fixup CMakeLists.txt to have a lower working minimum version
* Add .travis.yml and .travis.sh for autobuild
The stm32l4 loader expects a count of 32 bits words while its granularity is
really 64 bits.
This patch fixes this to simplify count calculation in run_flash_loader().

All the loaders returns remaining work count in r2, except stm32l0/1.
Make these loaders behaving as the others to simplify run_flash_loader() code.

This patch invert source and destination registers in the stm32l0 and stm32l1
loaders, so that it follows the same ABI as other stm32 loaders.
Doing that, the run_flash_loader() function can be simplified a little.

This patch simplifies run_flash_loader() function in preparation for error
propagation from backends.
Doing this, we have less call sites for stlink API.

Having a type of flash information has some advantages:
- Make the code easier to read
- Make adding family derivatives easier (only add a new entry in header file)
- Make the backends error propagation easier to implement (less places to fix)

As the libusb returns errors, make the backends propagates them so that
callers can decide to continue or stop task execution.

_stlink_usb_target_voltage already returns an error value.
If value return is positive, this is a voltage, if negative this is an error.
Check the return on callers side to inform there is an error in reading the
voltage, instead of notifying of a too low voltage.
