  Log:
  Rework the kernel environment subsystem.  We now convert the static
  environment needed at boot time to a dynamic subsystem when VM is
  up.  The dynamic kernel environment is protected by an sx lock.
  
  This adds some new functions to manipulate the kernel environment :
  freeenv(), setenv(), unsetenv() and testenv().  freeenv() has to be
  called after every getenv() when you have finished using the string.
  testenv() only tests if an environment variable is present, and
  doesn't require a freeenv() call. setenv() and unsetenv() are self
  explanatory.
  
  The kenv(2) syscall exports these new functionalities to userland,
  mainly for kenv(1).
