ethersubr: Make the mac address generation more robust

If we create two (vnet) jails and create a bridge interface in each we end up

with the same mac address on both bridge interfaces.

These very often conflicts, resulting in same mac address in both jails.

Mitigate this problem by including the jail name in the mac address.

| kern_jail: missing \0 termination check on osrelease parameter | | If a user spplies a non-\0 terminated osrelease parameter reading it back | may disclose kernel memory. | This is a problem in case of nested jails (children.max > 0, which is not | the default). Otherwise root outside the jail has access to kernel memory | by other means and root inside a jail cannot create a child jail. | | Add the proper \0 check at the end of a supplied osrelease parameter and | make sure any copies of the field will be \0-terminated.

Refine the "nojail" rc keyword, adding "nojailvnet" for files that don't apply to most jails but do apply to vnet jails. This includes adding a new sysctl "security.jail.vnet" to identify vnet jails.

Fix jail name checking that disallowed anything that starts with '0'. The intention was to just limit leading zeros on numeric names. That check is now imporved to allow catching the leading spaces and + that strtoul can pass through.
