devices/rtdmnet.c : fixed indentation and error handling.

devices/rtdmnet.c : abuse RTDM api to allow sendmsg and recvmsg to be called indirectly from userland cobalt process ioctl, while rtdm_socket is created from a kernel thread.

Set --enable-sii-assign by default.

Do not call watchdog function while frames are received.

RTDM : dropped wrong size check in mmap

RTDM: More IOCTL requests to be handled in primary mode

Xenomai 2 to 3 migration says "RTDM drivers implementing differentiated ioctl() support for both domains should serve all real-time only requests from ioctl_rt(), returning -ENOSYS for any unrecognized request, which will cause the adaptive switch to take place automatically to the ioctl_nrt() handler. The ioctl_nrt() should then implement all requests which may be valid from the regular Linux domain exclusively."

Cosmetic change : rtdm_in_rt_context instead of ipipe_root_p.

Xenomai won't merge .nrt ops delegation to rtdm task through rtpc. Moved it to rtdmnet.c.

Fixed wrong xeno_lib_ldflags, missing --posix --auto-init-solib

More hgignore

This fix a segfault in xenomai_posix example when calling pthread_setschedparam(cyclic_thread, ...) from main thread. As a side effect EL2004 becomes EL2088 - that's what IU have for testing.

More check in rtdm mmap, also use kernel memory instead of virtual memory.
