The driver vtables are read-only structures. This patch declares them as
'const' allowing the compiler to (optionally) put them in the RELRO
section. RELRO pages may be marked as read-only by the linker after
the relocations have been done ensuring that they aren't inadvertently
or maliciously altered at runtime.
Added the explicit support for auth NONE.
It needs to be added in all drivers/*/gprs-context.c atoms.
This method is already supported by all atoms that support
authentication (ie, all but Sierra' swmodem driver).
The behavior is left unchanged in case of inconsistent parameters:
if username is empty, then fallback to auth NONE.
Add support for automatic context activation by adding read_settings.
It also adds detach_shutdown to make sure context is cleaned up when
network registration is lost.
Previously, these drivers would check /sys/devices/virtual/misc/tun to
see if TUN is supported, and bail out otherwise. However, the tun module
can sometimes be autoloaded by opening the /dev/net/tun file. In this
case the /dev file already exists, but the /sys file only gets created
after the modul is loaded.
Additionally, the ppp code does not use the /sys file, but only the
/dev file, so checking for the existence of the latter seems a better
indicator of expected success.

This patch adds support for setting up a GPRS context and then switching
it into M-RAW_IP mode. The handling of the M-RAW_IP data stream is not
yet implemented.
