Move interrupt lock to device context and expose only this structure to
the read, write and set attributes device handler. This makes these
device handler independent of the general Termios infrastructure
suitable for direct use in printk() support.
This change starts with removing the effectively empty file
timerdrv.h. The prototypes for benchmark_timer_XXX() were in
btimer.h which was not universally used. Thus every use of
timerdrv.h had to be changed to btimer.h. Then the prototypes
for benchmark_timer_read() had to be adjusted to return
benchmark_timer_t rather than int or uint32_t.
I took this opportunity to also correct the file headers to
separate the copyright from the file description comments which
is needed to ensure the copyright isn't propagated into Doxygen
output.
Do not return from rtems_initialize_start_multitasking() and call
rtems_fatal() instead with a fatal source of RTEMS_FATAL_SOURCE_EXIT and
a fatal code with the exit status.
Remove all bsp_cleanup() functions. The boot_card() is now a no return
function.
The work areas (RTEMS work space and C program heap) will be initialized
now in a separate step and are no longer part of
rtems_initialize_data_structures(). Initialization is performed with
tables of Heap_Area entries. This allows usage of scattered memory
areas present on various small scale micro-controllers.
The sbrk() support API changes also. The bsp_sbrk_init() must now deal
with a minimum size for the first memory chunk to take the configured
work space size into account.
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.

special IOCTL in Clock_control. This was a hack which has existed
since before the Classic API Timer Manager was implemented. All
