Compiling the code from examples "code-block:: c" along with public
includes and a bsp exposed a few issues amongst a lot of false
positives. Address some of these:
* Terminate struct declarations with ';'. Mainly for pedantic
correctness.
* Show ptrdiff_t instead of size_t for the sbrk() prototype, matching
the current argument type in rtems.
* Replace some occurrences of unsigned16 with uint16_t.
* Fix odd type declaration, "uint8_t char*" -> "char*".
* Use appropriate helper to get chain head instead of invalid access to
nonexistent struct member.
* Remove several excess '\' escapes.
* Use RTEMS_SELF instead of undefined SELF.
* Use rtems_task instead of void for task functions.
* Add missing stack size parameter in task creation.
* Use rtems_interrupt_level instead of undefined rtems_interrupt.
* Correct return value format for rtems_object_id_get_api()
rtems_object_id_get_index() (enum and uint16_t) and also fix
corresponding print formatting.
* Correct return value documentation for rtems_object_id_get_class(),
rtems_object_id_get_node() and rtems_object_id_get_index()
int -> uint32_t.
* Use RTEMS_SUCCESSFUL instead of undefined RTEMS_STATUS_SUCCESSFUL and
fix return value variable name in rate monotonic examples.
* Use RTEMS_TIMEOUT instead of undefined TIMEOUT and RTEMS_PERIOD_STATUS
instead of undefined STATUS.
* Add missing fields to ftpd configuration.
* Correct parameter types in ftpd hook prototype,
unsigned char * -> void *.
* Fix various code-block:: attributes, c -> makefile and c -> shell.
* Add missing parenthesis in socket buffer memory calculation example.
* Remove typedef in declaration of mq_attr since it is defiend without
typedef in reality.
* Update siginfo_t declaration to match current reality.
* Update shell user command definition example to include mode, uid and
gid.
