When coverage is enabled fprintd test won't generate any .gcda file and so
apparently no data, this happens because gcov doesn't handle properly the
process termination when SIGTERM is used, and so when in fprintd.py we
terminate the process no coverage data is reported.
To avoid this, quit the main loop cleanly on SIGTERM, so that we will exit
from the main function cleanly, making libc to perform a gcov flush when we
exit the program.
Given that finger_name is set by GOptionEntry, make sure it's always
using allocated memory.
../utils/enroll.c:38:28: error: initialization discards ‘const’ qualifier

There's no need to declare it as extern in the header as it is already
declared in the source files where it's used.
Fixes:

With the stronger warnings enabled when building with meson, we get a
warning for all the fingers definitions:
../src/device.c:38:24: warning: initialization discards ‘const’ qualifier
from pointer target type [-Wdiscarded-qualifiers]
38 | [FP_FINGER_UNKNOWN] = "unknown",
As the `fingers` array name was shadowed in another file:
../src/device.c:1000:11: warning: declaration of ‘fingers’ shadows a
global declaration [-Wshadow]
1000 | GSList *fingers, *finger;
Like for the fprintd test, run the tests under valgrind if the `VALGRIND`
environment variable is set, and use the contents of the variable as the
path to the suppression file.
Use the device session data to store all the informations we care about
while a device is claimed, and make its cleanup easier.
Keep just one instance of the current context, given we use it only during
claim and release, and those are mutually exclusive operations.
Allocate SessionData using g_malloc(). There are no benefits to using
GSlice for a seldom used structure. This also allows use to use
g_clear_pointer() to free the struct.
We need to make sure that the max_tries variable isn't decremented
further when we have success in the verification loop. Add missing break
to do that.
