lib/embed/abort_: Implementation of abort_() function raising uPy exception.

pfalcon · pfalcon · commit c8b80e4740ba · 2016-07-30T00:35:50.000+03:00
Helpful when porting existing C libraries to MicroPython. abort()ing in
embedded environment isn't a good idea, so when compiling such library,
-Dabort=abort_ option can be given to redirect standard abort() to this
"safe" version.
