We note that:
0 <= BpfMap<K,V>.getMap()
is equivalent to
BpfMap<K,V>.isValid()
but the latter is far more kosher.
Unfortunately there is more non-kosher stuff happening in this
file, so we still need to define BPF_MAP_MAKE_VISIBLE_FOR_TESTING anyway.

In the BPF code, per-UID network access (e.g., for doze mode,
standby, etc.) is stored in UidOwnerValue structures. Each of
these stores that UID's rules in a 32-bit bitmask of
UidOwnerMatchType values, so the code can support ~31 match
types.
However, which match types are enabled is stored in
configuration_map at index UID_RULES_CONFIGURATION_KEY, and
configuration_map only stores 8-bit values. So it's not
possible to define more than 7 match types.
Widen configuration_map to from 8 to 32 bits to match the width
of UidOwnerValue.rule. This doesn't impact memory because
configuration_map only has 2 entries.

In order to get counted by mts code coverage, these native tests need to
be run as part of mts.

Configuration map index 1(CURRENT_STATS_MAP_CONFIGURATION_KEY) can only
have value 0(SELECT_MAP_A) or 1(SELECT_MAP_B). Return error if it is any
other values. Otherwise, read out of array boundary can cause memory
corruption or security issues.

Add new symbols to libservice-connectivity loaded on T only, and the

If libraries are moved from the platform to a module, the test
will fail with:
CANNOT LINK EXECUTABLE "/data/local/tmp/libnetworkstats_test/arm64/libnetworkstats_test": library "libnetworkstats.so" not found: needed by main executable
This may be because it can't find libnetworkstats.so because that
is in platform.
In any case, since this is the test for libnetworkstats,
dynamically linking libnetworkstats is incorrect, because it
means if the same CL modifies both libnetworkstats and its test,
that CL will run the modified test against the unmodified
libnetworkstats.so on the device, when running updating tests
without reflashing the device.
Also remove libutils because it does not seem to be needed.
Test: atest libnetworkstats_test passes with libraries moved

Two reason for renaming:
1. Avoid module name collision in sc-mainline-prod branch.
2. The libnetdbpf was misnamed before.
