Currently, this does nothing. It just sets a flag that nothing looks at.
Don't get all wound up - we haven't abandoned our principles. This will
eventually be used to allow enterprise-enrolled customers to prevent
unauthorized use of developer mode in the Chrome OS devices that THEY OWN.
This is not Google deciding to turn a feature off, it's allowing the OWNER
to control the use of the feature. In some situations, the owner can be held
liable for what others do with the owner's equipment. This will help the
owner avoid those situations while their device is out of their immediate
control.

Set the flag with:
crossystem block_devmode=1
Clear it with:
crossystem block_devmode=0
Retrieve the value ("0" or "1") like so:
val=$(crossystem block_devmode)
echo "the flag is $val"
or just test it directly like so:
if crossystem 'block_devmode?1' ; then
echo "devmode is blocked"
else
echo "devmode is allowed"
fi
It should be persistent across reboots.

This adds a VB_MAX_STRING_PROPERTY for callers that don't
want to guess at how big to make their buffers.
Additionally, it changes the size parameter to VbGetPropertyString()
from int to size_t.

Querying "debug_build" allows the caller to determine whether the
image has requested debug, independent of the setting of the
dev_mode switch.
