[GIT] Rename frontend functions to be unique

[GIT] Rename frontend functions to be unique

[Ian Campbell]

All Xen frontend drivers have a couple of identically named functions
which makes figuring out which device went wrong from a stacktrace
harder than it needs to be. Rename them to something specificto the
device type.

The following changes since commit 167bafd71a448f50dba5db362b813029838d04c9:
  Jeremy Fitzhardinge (1):
        Merge branch 'xen/dom0/apic' into xen/master

are available in the git repository at:

  git://xenbits.xensource.com/people/ianc/linux-2.6.git for-jeremy/rollup

or individually from 
  git://xenbits.xensource.com/people/ianc/linux-2.6.git for-jeremy/netfront
  git://xenbits.xensource.com/people/ianc/linux-2.6.git for-jeremy/blkfront
  git://xenbits.xensource.com/people/ianc/linux-2.6.git for-jeremy/netchannel2

Ian Campbell (3):
      xen: use less generic names in netfront driver.
      xen: use less generic names in blkfront driver.
      xen: use less generic names in netfront2 driver.

Doh, this hunk was obviously accidental. I've updated the git branch.

BTW, I have a single xen/frontend branch for netfront and blkfront, on 
the assumption that changes to them are going to be minor bugfix type 
stuff.  I cherry-picked your patches over to it.
