  commit 0897514b4b376a167f968f79c6ea0dee1061458e

      tools/oxenstored: Avoid allocating invalid transaction ids
      
      The transaction id of 0 is reserved, meaning "not in a transaction".  It 
is up
      to the xenstored server to allocate transaction ids.  While oxenstored 
starts
      its ids at 1, but insufficient care is taken with truncation cases.
      
      A 32bit oxenstored has an int with 31 bits of width, meaning that the
      transaction id will wrap around to 0 after 2 billion transactions.
      
      A 64bit oxenstored has an int with 63 bits of width, meaning that once 4
      billion transactions are used, the allocated id will be truncated when 
written
      into the uin32_t field in the ring.  This causes the client to reply with 
the
      truncated id, breaking any further attempt to use any transactions.
      
      Limit all transaction ids to the range between 1 and 0x7ffffffe.  This is 
the
      best which can be done without making oxenstored depend on Stdint or 
Cstruct,
      yet still work for 32bit builds.
      
      Also check that the proposed new transaction id isn't currently in use.  
For
      the first 2 billion transactions there is no chance of a collision, and 
after
      that, the chance is at most 20 (the default open transaction quota) in 2
      billion.

      tools/oxenstored: Avoid allocating invalid transaction ids
      
      The transaction id of 0 is reserved, meaning "not in a transaction".  It 
is up
      to the xenstored server to allocate transaction ids.  While oxenstored 
starts
      its ids at 1, but insufficient care is taken with truncation cases.
      
      A 32bit oxenstored has an int with 31 bits of width, meaning that the
      transaction id will wrap around to 0 after 2 billion transactions.
      
      A 64bit oxenstored has an int with 63 bits of width, meaning that once 4
      billion transactions are used, the allocated id will be truncated when 
written
      into the uin32_t field in the ring.  This causes the client to reply with 
the
      truncated id, breaking any further attempt to use any transactions.
      
      Limit all transaction ids to the range between 1 and 0x7ffffffe.  This is 
the
      best which can be done without making oxenstored depend on Stdint or 
Cstruct,
      yet still work for 32bit builds.
      
      Also check that the proposed new transaction id isn't currently in use.  
For
      the first 2 billion transactions there is no chance of a collision, and 
after
      that, the chance is at most 20 (the default open transaction quota) in 2
      billion.
