The network_config was not being copied to network_info when
updated. This caused any new settings to be lost if the network
configuration file was updated during runtime.

This happens if hostapd is killed ungracefully which is done in
some tests.

When logging is enabled TLS debugging is turned on which creates
a PEM file during runtime. There is no way for IWD itself to clean
this up since its meant to be there for debugging.

This was added for logging but --monitor suffers the same warning
without setting msize as well.

Occationally python will fatally terminate trying to load a test
using importlib with an out of memory exception. Increasing RAM
allows reliable exection of all tests.

Doing this is redundant since the dbus object is initialized
anyways when a new test starts.

testScan was creating 10 separate hidden networks which
sometimes bogged down hostapd to the point that it would
not start up in time before test-runner's timeouts fired.
This appeared to be due to hostapd needing to create 10
separate interfaces which would sometimes fail with -ENFILE.

The test itself only needed two separate networks, so instead
the additional 8 can be completely removed.

After some code changes the FT-FILS AKM was no longer selectable
inside network_can_connect_bss. This normally shouldn't matter
since station ends up selecting the AKM explicitly, including
passing the fils_hint, but since the autotests only included
FT-FILS AKMs this caused the transition to fail with no available
BSS's.

To fix this the standard 8021x AKM was added to the hostapd
configs. This allows these BSS's to be selected when attempting
to roam, but since FT-FILS is the only other AKM it will be used
for the actual transition.

The Process class requires the ability to write out any processes
output to stdout, logging, or an explicit file, as well as store
it inside python for processing by test utilities. To accomplish
this each process was given a temporary file to write to, and that
file had an IO watch set on it. Any data that was written was then
read, and re-written out to where it needed to go. This ended up
being very buggy and quite complex due to needing to mess with
read/write pointers inside the file.

Popen already creates pipes to stdout if told, and they are accessable
via the p.stdout. Its then as simple as setting an IO watch on that
pipe and keeping the same code for reading out new data and writing
it to any files we want. This greatly reduces the complexity.
