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.

Use new RTDM's mmap, not anymore a special case compared to normal linux mmap.

Fixed rtdmnet.c PFX and removed useless commented code.

rtdmnet module should follow same (un)loading rules as generic module

Added devices/rtdmnet.c, heavily based on devices/generic.c, and with similar purpose. It uses Xenomai's RTNet/RTDM socket instead of Linux socket.

Fix C/C++ linking problem in tool/ethercat

Continued update of master's rtdm part to xenomai 3 : ioctl context now obtained from rtdm_fd

Continued update of master's rtdm part to xenomai 3 : rtdm_user_info_t now replaced by rtdm_fd

migrate posix xenomai example to Xenomai3

migrate native xenomai example to Xenomai3

rt_dev_* has been abandonned in Xenomai3, on user side we use the regular POSIX I/O calls exposed by libcobalt

rtdm skin is equivalent to posix in Xenomai3's xeno-config. Replace XENOMAI_RTDM_*FLAGS by XENOMAI_LIB_*FLAGS to distinguish lib/example flags.

Add module installation path to configure options

Intermediate state while updating master's RTDM part to Xenomai 3

Added --with-xenomai-config to override xenomai config command, also allowing special environment variables to be passed.

Example : --with-xenomai-config="DESTDIR=/path/to/staging /path/to/xeno-config"

Fixed scheduler settings in dc_user example; use CLOCK_MONOTONIC.

Use sched_setscheduler() to set priority in user example.

Applied 0002-use-setup_timer-for-v4.15.patch from Beckhoff.

Applied CCAT patch 0001-fix-ccat-netdev-for-v4.11.patch from Beckhoff.

Ignore missing SDO entries in output.

Improved buffer overflow messages.

Support scheduler parameters in kernels >= 4.11.

Added missing configure options to documentation.

Respect bashisms.

Fixed statistics filter initialisation.

Doc.

EtherCAT functionality of igb driver.

Added clean igb driver from kernel 3.18 (no EtherCAT yet).

Do not build GPIO part of CCAT if GPIO is not configured in kernel.

Forgot Makefile.orig.
