All ChronoVu LA8 files (*.kdt extension usually) are exactly 8388613
bytes in size (8MB + 5 bytes). Check this, when trying to autodetect the
file format, to reduce the likelihood of 'chronovu-la8' being
autodetected on all binary files (instead of 'binary').
Avoid plain malloc()/free() in sr/srd, especially in the API calls.
Also avoid g_malloc*() in favor of g_try_malloc*().
Use g_strdup() instead of strdup() so that we can use g_free()
consistently everywhere.
Exceptions: Stuff that is allocated via other libs (not using glib),
should also be properly free'd using the respective free-ing function
(instead of g_free()). Examples: Stuff allocated by libusb, libftdi, etc.
Also, use sr_err() instead of sr_warn() for actual errors. sr_warn() is
meant for non-fatal/uncritical warnings.
This will come back in some form or another later, but for now
don't clutter the API with non-working stuff. Removing stuff from APIs
is not possible without breaking the API, adding stuff later is simpler.
