Removed two return warnings, was to triggerhappy on release

Changes: Added existing namecheck when creating files Lots of static analysis bugs #6 Added rename func Fix SPIFFS_read length when reading beyond file size Added reading beyond file length testcase Made build a bit more configurable Changed name in spiffs from "errno" to "err_code" due to conflicts compiling in mingw Improved GC checks, fixed an append bug, more robust truncate for very special case GC checks preempts GC, truncate even less picky Struct alignment needed for some targets, define in spiffs config #10 Spiffs filesystem magic, definable in config
