AW: Some refactoring proposals

...

Here's a few refactoring proposal that I'd like to get done. But before I invest too much time in them I'd like to be sure there are

no

...

objections ... (I hate implementing stuff for nothing).

• Split layer23/src into
  • common: what makes liblayer23, purely generic stuff that needs

binding together to define an app

• mobile: The real complete mobile application
• misc: The test applications and their support code layer23 (which

I'd rename bcch_dump since that's what it does), echo_test,

bcch_scan)

Sounds fine with me. If Andreas doesn't mind, I'm happy to merge a

branch

containing this split

i don't mind!
