[Xenomai-core] [announce] Xenomai v2.5.3

[Gilles Chanteperdrix <gilles.chanteperdrix@xenomai.org>]

Hi,

here comes Xenomai v2.5.3, codenamed "Hordes Of Locusts" available from 
Xenomai download area:
http://download.gna.org/xenomai/stable/xenomai-2.5.3.tar.bz2

It contains several fixes for annoying bugs in v2.5.2:
- fix compilation issues with uclibc
- fix a stack overflow due to the stack faulting code on powerpc
- fix of a regression in the RPI code introduced by a clueless RPI 
newbie.

Upgrade of several components:
- ARM I-pipe patchs for more recent kernel versions, with support for 
new platforms, ARM imx51 based Babbage board and OMAP3 based IGEPv2 
board, and some fixes in ARM VFP code;
- RTDM, reverted using the "conforming" mode bit for RTDM syscalls to
the "current" mode bit, adding an rtdm_is_rt_capable service for 
driver such as analogy which need the "current" mode behaviour, as 
well as fixes in analogy to use that new service;
deprecated the rt handlers for open and close, dropped them in 
the in-tree drivers, reworked the close code to be more friendly;
- Debian packaging, upgrade to the level of Debian package version 
2.5.2-2.
