Added trace statements through LFS_YES_TRACE
To use, compile and run with LFS_YES_TRACE defined:
make CFLAGS+=-DLFS_YES_TRACE=1 test_format
The name LFS_YES_TRACE was chosen to match the LFS_NO_DEBUG and
LFS_NO_WARN defines for the similar levels of output. The YES is
necessary to avoid a conflict with the actual LFS_TRACE macro that
gets emitting. LFS_TRACE can also be defined directly to provide
a custom trace formatter.
Hopefully having trace statements at the littlefs C API helps
debugging and reproducing issues.
