Changeset 2e711f2 in rtems-docs

Address several issues from compiling examples

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.
