This changes "hs20-osu-client browser <URL>" behavior to validate the
HTTPS server certificate against the system trust roots. The new command
line argument -T can be used to disable this validation.
This does not change behavior for SPP/OMA-DM triggered OSU operation,
i.e., they continue to not mandate server certificate validation for now
to avoid breaking existing test cases.

hs20_web_browser() was previously hardcoded to not perform strict TLS
server validation. Add an argument to this function to allow that
behavior to be configured. The hs20-osu-client users are still using the
old behavior, i.e., not validating server certificates, to be usable for
testing purposes.

This updates SP/<FQDN> directory with following permissions on Android

There is no need to allow symlink dereferencing in these cases where a
file (including directories and sockets) are created by the same
process, so use the safer lchown() variant to avoid leaving potential
windows for something external to replace the file before the chown()
call. The particular locations used here should not have write
permissions enabled for processes with less privileges, so this may not
be needed, but anyway, it is better to make these more restrictive
should there be cases where directory permissions are not as expected
for a good deployment.

hs20-osu-client refused to do anything if it could not find devinfo.xml
from the current working directory. This is a bit excessive since that
file was used in init_ctx() only to fill in ctx->devid which is used
when constructing OMA DM messages.
Move the check for ctx->devid into OMA DM specific code so that other
hs20-osu-client functionality can be used without the devinfo.xml file.

Previously, this was done only for the subscription remediation/update
trust root. The other downloaded files were also verified, but the OSU
server was not notified if the files were found to be invalid.
Modify hs20-osu-client behavior to explicitly notify the OSU server if
any of the three trust root types cannot be successfully downloaded.

When OSEN is used in the BSS that is shared both for production data and

This commit allows any process running with group id of AID_WIFI to
read/write files to osu-info directory. Also, it allows other users to
read and search the osu-info directory.

write there on Android where the wpa_supplicant process does not run as

As part of OSU, the AAA TrustRoot cert is downloaded into SP/<fqdn>
