Use correct prototype of benchmark_timer_read()

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.

4 * @brief Configuration Table Template that will be Instantiated
5 * by an Application
6 *
7 * This include file contains the configuration table template that will
8 * be instantiated by an application based on the setting of a number
9 * of macros.  The macros are documented in the Configuring a System
10 * chapter of the Classic API User's Guide
11 *
12 * The model is to estimate the memory required for each configured item
13 * and sum those estimates.  The estimate can be too high or too low for
14 * a variety of reasons:
15 *
16 * Reasons estimate is too high:
17 *   + FP contexts (not all tasks are FP)
18 *
19 * Reasons estimate is too low:
20 *   + stacks greater than minimum size
21 *   + messages
22 *   + application must account for device driver resources
23 *   + application must account for add-on library resource requirements
24 *
25 * NOTE:  Eventually this may be able to take into account some of
26 *        the above.  This procedure has evolved from just enough to
27 *        support the RTEMS Test Suites into something that can be
28 *        used remarkably reliably by most applications.

629 *
630 * By reducing the number of priorities in a system,
631 * the amount of RAM required by RTEMS can be significantly
632 * reduced.  RTEMS allocates a Chain_Control structure per
633 * priority and this structure contains 3 pointers.  So
634 * the default is (256 * 12) = 3K on 32-bit architectures.
635 *
636 * This must be one less than a power of 2 between
637 * 4 and 256.  Valid values along with the application
638 * priority levels and memory saved when pointers are
639 * 32-bits in size are:
640 *
641 *   + 3,  2 application priorities, 3024 bytes saved
642 *   + 7, 5 application priorities, 2976 bytes saved
643 *   + 15, 13 application priorities, 2880 bytes saved
644 *   + 31, 29 application priorities, 2688 bytes saved
645 *   + 63, 61 application priorities, 2304 bytes saved
646 *   + 127, 125 application priorities, 1536 bytes saved
647 *   + 255, 253 application priorities, 0 bytes saved
