env: Add option to only ever append environment

2020-07-31T14:13:00+00:00

Add configuration option which prevents the environment hash table to be
ever cleared and reloaded with different content. This is useful in case
the first environment loaded into the hash table contains e.g. sensitive
content which must not be dropped or reloaded.

env: correctly handle env_load_prio

2020-07-31T14:13:00+00:00

Only update gd->env_load_prio in generic function env_load()
and no more in the weak function env_get_location() which is
called in many place (for example in env_driver_lookup, even
for ENVOP_SAVE operation).

This patch is a preliminary step to use env_driver_lookup()/
env_get_location() in new function env_select() without
updating gd->env_load_prio.

env: correct overflow check of env_has_init size

2020-07-26T18:35:30+00:00

Correct the overflow check of the bit-field env_has_init with
the max value of env_location= ENVL_COUNT and no more with the
size of env_locations.

This bit-field is indexed by this enumerate and not by the position in
the env_locations (only used in env_get_location) and the
2 values are different, depending of thea ctivated CONFIG_ENV_IS_ options.
