    Phone: Set MSISDN on boot from saved setting if SIM returned empty "My Phone Number"

    Some carriers don't set the MSISDN (My Phone Number) and CM remedied
    that by adding a setting in "Additional settings" in Call Settings
    which saves a new MSISDN to the SIM. However, some phones fails to
    save the MSISDN to the SIM and another remedy was added to set it
    every boot from the stored value. However, the current implementation
    only sets it if the framework returns a null value. This patch also
    sets it if the framework returns an empty string.

    Patch Set 3:
    - Fixed simstate checking as the intent extra is a string not an
      integer
    - Removed airplane mode checking as simstate will be triggered anyway

    Phone: Fix race condition in BOOT_COMPLETED intent

    BOOT_COMPLETED was triggering a read (and write) of SIM extra
    fields, regardless of whether the SIM was actually ready for it
    or not.
    If the boot happened to complete before the radio layer
    was ready, we were trying to do iccIO before we were allowed to.
    This resulted in errors for most phones, but on at least one it caused
    the whole iccIO interface to lock up until the next reboot (where the
    same would probably happen again)

    So... trigger the write with the SIM_READY intent itself instead of
    using BOOT_COMPLETED

    phone: Fix case where MSISDN alpha tag is not set

    The new "My phone number" option was not being saved to the SIM because
    the alpha tag was not previously set. This change externalizes the
    preference code and defaults the alpha tag to "Voice Line 1".
