[Openais] [PATCH 1/2] flight recorder: switch from int to bytes for requested allocation

[Fabio M. Di Nitto]

The flight recoder buffer size as specified in LOGSYS_DECLARE_SYSTEM
or _logsys_rec_init was expressed in number of ints. A developer asking
to allocate 512K would get a 2M allocation on a machine with sizeof(int) = 4.

This is confusing and the patch addresses it:

- rename rec_size to fltsize for external API (no type change),
  because rec_size is used many times internally for other reasons
  and it can be confusing.

- rename size to fltsize in _logsys_rec_init.

- document what we allocate and why.

- swap comments around to match the code.

- introduce a simple macro to perform rounding (stolen from linux-2.6.git).
