0c9d5d8166 Add dfu bootloader update application and use absolute delay for stlink
Hello,

appended 3 patches
- adds a dfu-bootloader appliaction
- uses absolute delays when waiting for pull-up delays on the STLINK
(hopefully fixes issue #30)

Updating the dfu-bootloader by additional application is helpfull for the
STLINK, as for flashing the bootloader by SWDb otherwise jumpers need to be
soldered or external SWD is not possible.
Use like:
- dfu-util -s 0x08002000:leave -D dfu_upgrade.bin
- dfu-util -s 0x08000000:leave -D blackmagic_dfu.bin
- Push reset buttom and reconnect to enter new dfu bootloader
- dfu-util -s 0x08002000:leave -D blackmagic.bin
