doc/Host-tools-overview: tiffs-mkfs description updated
The first version of tiffs-mkfs did not include a journal file in the created
FFS, expecting the firmware to create it on first boot. All historical
firmwares prior to a recent FC fix (2020-05) contain a bug in that code path,
thus images made with the first version of tiffs-mkfs were only acceptable to
very recent FC firmwares. tiffs-mkfs has now been extended to include an empty
journal in the created FFS, thus the restriction of working with recent fw only
has been lifted.

The library built in this directory is a host side library, not for the target. This library implements some functions for handling packet exchanges with GPF, and it will be linked by some of the programs in the rvinterf suite. It needs to be noted that the RVTMUX channel belonging to GPF was named RVT_L23_HEADER by TI, and as a result, I thought that these packets related specifically to the higher layers of the protocol stack. But now we know that hierarchically speaking, GPF sits *below* L1, not above, and GPF packets should not be automatically associated with G23. This realization was made fairly late, thus "g23" appears in a bunch of function names, and in the name of this library.
