Use posix keys for current shell environment instead of task variables. With
this patch the shell needs one posix-key and one posix-key-value-pair
configured.
Update documentation for the shell.
Adapt samples/fileio:
- Add necessary objects.
- Add login function and custom device name for better testing of the shell.
* cdtest/main.cc, fileio/init.c, fileio/system.h, pppd/pppdapp.c,
ticker/system.h, ticker/tasks.c: Eliminate test routines
TICKS_PER_SECOND and get_ticks_per_second() in favor of new
rtems_clock_get_ticks_per_second().
* fileio/init.c, fileio/system.h, iostream/init.cc,
loopback/init.c, pppd/init.c, pppd/pppdapp.c: Do not build if
BSP_SMALL_MEMORY is defined. Remove this code once a better way is
supported by the build system.
* fileio/system.h, ticker/system.h: Add new Object Services collection.
This changed the name of a few previously public but undocumented
services and added a some new services.
