Adjust build support files to new directory layout.
This patch is a part of the BSP source reorganization.

Use only one timer driver variant based on the standard PowerPC time
base.

The only consumer of this variable was the ppc403 clock driver used by
the
* haleakala,
* virtex, and
* virtex4
BSPs which set bsp_timer_internal_clock unconditionally to true.
Update #3285.

BSPs can use the bsp_fatal_extension() to provide BSP-specific fatal
error handling. There is no need for a _BSP_Fatal_error().
Close #3246.

Due to a new rtems_panic() implementation, it is possible to replace the
PowerPC-specific BSP_panic() with rtems_panic(). Remove BSP_panic()
implementations.

The BSP_output_char should output a char and not mingle with high level
processing, e.g. '\n' to '\r\n' translation. Move this translation to
rtems_putc(). Remove it from all the BSP_output_char implementations.
Close #3122.

Instead of SPRG0 (= special purpose register 272) use the new global
symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask.
The benefit is that it is now possible to disable interrupts without
further run-time initialization in boot_card().
At least on Freescale e500 cores this leads also to a faster execution
since the mfmsr and mfspr instruction require four cycles to complete.
The instructions to load the mask value can execute while the mfmsr is
in progress.

Add a CPU counter interface to allow access to a free-running counter.
It is useful to measure short time intervals. This can be used for
example to enable profiling of critical low-level functions.
Add two busy wait functions rtems_counter_delay_ticks() and
rtems_counter_delay_nanoseconds() implemented via the CPU counter.

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.
