Server ids in /vice/db/servers

All servers in a coda cell need to have a unique number to identify them. The servername to identifier mappings have to be defined by the administrator in the file /vice/db/servers on the SCM. The format of this file is as follows:

servernameX.domain.name    1
  servernameY.domain.name    2
  ...

There are currently several limitations to which identifiers are actually usable.

• all numbers must fit in a single byte.
• 0 and -1 (255) are used in error conditions.
• 127 is used to identify `replicated volumes'.

This leaves us with a usable range of 1-126 and 128-245 for server identifiers.
