This change adds rtems_printf and related functions and wraps the
RTEMS print plugin support into a user API. All references to the
plugin are removed and replaced with the rtems_printer interface.
Printk and related functions are made to return a valid number of
characters formatted and output.
The function attribute to check printf functions has been added
to rtems_printf and printk. No changes to remove warrnings are part
of this patch set.
The testsuite has been moved over to the rtems_printer. The testsuite
has a mix of rtems_printer access and direct print control via the
tmacros.h header file. The support for begink/endk has been removed
as it served no purpose and only confused the code base. The testsuite
has not been refactored to use rtems_printf. This is future work.
Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
* libmisc/stackchk/check.c: If this port does not allocate the
interrupt stack, then it must always be a thread stack. Do not
include code to print the interrupt stack information.

* libmisc/stackchk/check.c: Rewrote loop to avoid possible buffer
overruns when the pattern area size is not a multiple of 16. There
were no current ports impacted by this but better to be safe.

Simplified block resize. Improved heap walk. Changed heap layout to
avoid a special case for _Heap_Is_used() and _Heap_Is_free().
* libmisc/stackchk/check.c: Update for heap API changes.

simple type to a union of an unsigned 32 bit integer and a pointer.
This should help eliminate weird casts between u32 and pointers in
various places. The APIs now have to explicitly call _u32 or _string
versions of helper routines. This should also simplify things and
eliminate the need for ugly casts in some cases.

Always print a blown message using the same routine. Now works with
GNAT RTS -fstack-checking if you have patch for the RTEMS specific
support in your GCC version.

+ rtems_cpu_usage_report
As demonstration, the http netdemo can now print out stack

monotonic period statistics and CPU usage statistics. This capability
is enabled by default although may be conditionally disabled by the
user. It could be too much overhead on small targets but it does not
appear to be bad in early testing. Its impact on code size has not
been evaluated either. It is possible that both forms of statistics
gathering could be disabled with further tweaking of the conditional
compilation.
