* posix/Makefile.am, posix/include/rtems/posix/psignal.h: Add stubs for
gettimer() and setitimer().
* posix/src/getitimer.c, posix/src/setitimer.c: New files.
* libcsupport/Makefile.am, posix/Makefile.am: Comment out including
files which contain routines which are now provided by the newlib
posix subdirectory. Document a few which come from the unix directory.
* score/include/rtems/score/heap.h,
score/include/rtems/score/protectedheap.h,
score/include/rtems/score/wkspace.h, score/src/heap.c,
score/src/heapallocate.c, score/src/heapallocatealigned.c,
score/src/heapextend.c, score/src/heapresizeblock.c,
score/src/heapsizeofuserarea.c, score/src/pheapgetblocksize.c,
score/src/wkspace.c: Revert use of ssize_t. This type is not
guaranteed to be able to represent a positive number greater than the
size of a single allocatable object. We needed a type that is able to
represent the size of a pool of multiple allocatable objects or
potentially nearly all memory.
* libcsupport/src/newlibc_exit.c, score/src/threadhandler.c: Do not
think about running init/fini on AVR. We do not know what mechanism
it uses but this is not it.
* Makefile.am, preinstall.am, rtems/score/cpu.h: Now performs context
switches and many tests run.
* context_init.c, context_switch.S, cpu.c, cpu_asm.c: New files.
PR 1331/networking
* libmisc/shell/shell.c, telnetd/check_passwd.c, telnetd/telnetd.c,
telnetd/telnetd.h: Improve comments and explanation of options to
rtems_telnetd_initialize. Add extra newline to login sequence from
shell.
* context_switch.S, cpu_asm.c, rtems/score/cpu.h: Add support for
restarting the currently executing thread. Fine tune alignment factor
as two-byte aligned and use this for critical structures.
* libcsupport/src/printk.c: Addresses can be larger than integers
so use long for %p formats.
* score/inline/rtems/score/address.inl: Offsets can be positive or
negative, so use int32_t. Also do math with intptr_t since there
are cases where the number of bits in an address do not equal the
number of bits in an integer.
* score/inline/rtems/score/heap.inl: Offsets can be positive or
negative, so use int32_t.
* libmisc/monitor/mon-monitor.c, rtems/include/rtems/rtems/types.h: Do
not have fp context type when no hardware or software floating point
is available.
* libcsupport/src/malloc_statistics_helpers.c,
libcsupport/src/realloc.c, rtems/include/rtems/rtems/region.h,

score/src/heapsizeofuserarea.c, score/src/pheapgetblocksize.c,
score/src/wkspace.c: Change size_t to ssize_t on all Heap, Workspace
and Region calls. On 16-bit architectures, size_t can be 16-bits
which would limit sizes to 64K.
* libmisc/shell/main_cp.c, libmisc/shell/main_ls.c,
libmisc/shell/main_mv.c, libmisc/shell/main_netstats.c,
libmisc/shell/main_rm.c, libmisc/shell/shell_script.c: Newlib >
1.16.0 requires __need_getopt_newlib to be defined to get visibility
on the reentrancy extensions.
* Makefile.am: Move duplicated context switch code to score/cpu. This
has been used to run tests on the simulator BSP as SH1, SH2, and SH4.
* context.c: New file.
