***************************************************************************
* System activity data files
*
* The rule is: "strict writing, read any", meaning that sar/sadc can
* only append data to a datafile whose format is strictly the same as that
* of current version (checking FORMAT_MAGIC is not enough), but sar/sadf
* can read data from different versions, providing that FORMAT_MAGIC value
* has not changed (note that we are talking here of data read from a file,
* not data that sar reads from sadc, in which case the "strict" rule applies).
*
* Format of system activity data files:
* __
* |
* | file_magic structure
* |
* |--
* |
* | file_header structure
* |
* |-- --|
* | |
* | file_activity structure | * sa_act_nr
* | |
* |-- --|
* | |
* | record_header structure |
* | |

* | |
* |-- |
* |(__nr_t) |
* |-- |
* | |
* | Statistics structure(s)... |
* | |
* |-- --|
*
* Note: For activities with varying number of items, a __nr_t value, giving
* the number of items, arrives before the statistics structures so that
* we know how many of them have to be read.
* NB: This value exists for all the activities even if they share the same
* count function (e.g. A_NET_DEV and A_NET_EDEV). Indeed, statistics are not
* read atomically and the number of items (e.g. network interfaces) may have
* varied in between.
*
* If the record header's type is R_COMMENT then we find only a comment
* following the record_header structure.
* If the record_header's type is R_RESTART then we find only the number of CPU
* (of type __nr_t) of the machine following the record_header structure.
